TBAS Exam — Questions and Answers
Question 1: Which instrument is used to determine the rate of altitude change rather than the actual current altitude?
- Attitude indicator
- Vertical speed indicator (VSI) (Correct answer)
- Altimeter
- Airspeed indicator
Correct answer: Vertical speed indicator (VSI)
The vertical speed indicator (VSI) shows the rate of altitude change in feet per minute, while the altimeter shows the current altitude.
Question 2: An instrument scan shows decreasing airspeed, a nose-high attitude on the attitude indicator, and a positive climb rate on the VSI. This combination most likely indicates:
- Level accelerated flight
- Normal cruise flight
- A spiral dive is developing
- The aircraft is approaching a stall (Correct answer)
Correct answer: The aircraft is approaching a stall
Decreasing airspeed combined with a nose-high attitude and a climbing VSI reading are classic indicators of an aircraft approaching a power-off stall.
Question 3: The auditory processing speed sections of the TBAS often involve responding to specific numbers while ignoring letters and other numbers. This format is designed to assess the candidate's ability to:
- Filter relevant from irrelevant stimuli and react decisively. (Correct answer)
- Perform complex mental calculations under pressure.
- Recall detailed information from a long passage that was read aloud.
- Follow a lengthy and complicated sequence of commands.
Correct answer: Filter relevant from irrelevant stimuli and react decisively.
This task is a direct measure of a candidate's ability to filter out irrelevant auditory information (the non-target letters and numbers) and focus only on the relevant stimuli (the target numbers), then execute a quick response. This simulates a pilot's need to pick out a critical radio call from background chatter.
Question 4: Which of the following is a common mistake pilots make during the Horizontal Tracking Test?
- Maintaining too low an airspeed
- Using the rudder instead of the ailerons for horizontal adjustments (Correct answer)
- Focusing too much on the vertical position of the target
- Ignoring altitude changes
Correct answer: Using the rudder instead of the ailerons for horizontal adjustments
A common mistake in the Horizontal Tracking Test is incorrectly using rudder pedals for horizontal adjustments instead of ailerons. While rudder pedals control yaw, ailerons are designed for roll, which directly affects lateral movement. Misusing controls demonstrates a lack of understanding of aircraft dynamics and hinders accurate horizontal tracking.
Question 5: Within the TBAS multitasking environment, what is the specific and primary role of 'working memory' regarding the auditory challenge?
- Improving the physical reaction speed to the auditory cue.
- Actively holding the set of target numbers for ongoing comparison. (Correct answer)
- Filtering out distracting non-target auditory stimuli.
- Reducing the cognitive load of the simultaneous tracking tasks.
Correct answer: Actively holding the set of target numbers for ongoing comparison.
Working memory acts as the brain's 'mental workspace' for temporarily holding and manipulating information. Its primary role in this context is to keep the pre-briefed target numbers (e.g., 3, 6, 9) actively available for immediate comparison against the incoming stream of auditory information.
Question 6: A candidate is engaged in a complex TBAS multitasking scenario that includes two-dimensional tracking with a joystick and horizontal tracking with rudder pedals. What is the most effective visual scanning strategy for managing both tasks simultaneously?
- Stare at a fixed point between the two targets and react to movement in either area.
- Concentrate exclusively on the horizontal target, making quick glances at the two-dimensional target.
- Focus primarily on the two-dimensional target, using peripheral vision for the horizontal target. (Correct answer)
- Alternate focus between the two targets every 1-2 seconds, regardless of their movement.
Correct answer: Focus primarily on the two-dimensional target, using peripheral vision for the horizontal target.
When performing both the airplane (2D) tracking and horizontal tracking tasks, a common and effective strategy is to maintain primary visual focus on the more complex, two-dimensional target while using peripheral vision to monitor and control the simpler, one-dimensional horizontal target, making occasional quick glances as needed.
Question 7: An aircraft climbs from 6,500 feet to 8,200 feet. How many feet did the aircraft ascend?
- 2,200 feet
- 1,500 feet
- 1,300 feet
- 1,700 feet (Correct answer)
Correct answer: 1,700 feet
8,200 minus 6,500 equals 1,700 feet of altitude gained.
Question 8: During the Combined Tracking Coordination test, a candidate consistently responds correctly to the auditory cues and keeps the vertical target centered, but their horizontal tracking score is poor. This specific pattern of performance most likely indicates a difficulty with:
- Auditory processing speed.
- Foot-eye coordination using the rudder pedals. (Correct answer)
- Hand-eye coordination using the joystick.
- Multitasking and cognitive load management.
Correct answer: Foot-eye coordination using the rudder pedals.
The candidate is successfully managing the auditory task (ears/trigger finger) and the vertical tracking task (hand/joystick). The isolated failure is in the horizontal tracking task, which is controlled by the rudder pedals. This points directly to a weakness in foot-eye coordination or control with that specific input device.
Question 9: During a multi-tasking portion of the TBAS, a candidate is simultaneously tracking two targets and listening for auditory cues. A target number is announced amidst distracting auditory letters and numbers. What is the most critical skill being assessed in this specific auditory task?
- Sound localization
- Selective attention (Correct answer)
- Pitch discrimination
- Auditory memory recall
Correct answer: Selective attention
This task specifically measures a candidate's selective attention, which is the ability to focus on a particular auditory stimulus (the target number) while filtering out other distracting, irrelevant sounds (other letters and numbers). While memory is involved, the primary challenge is first selecting the correct information to attend to.
Question 10: What is the primary cognitive challenge introduced in the Combined Tracking Coordination subtest that is not present when its component tasks are performed individually?
- Spatial orientation
- Fine motor precision
- Auditory acuity
- Divided attention (Correct answer)
Correct answer: Divided attention
While the individual tasks measure motor skills and auditory processing, the core purpose of combining them is to assess a candidate's ability to divide their attention and effectively manage multiple, unrelated stimuli and tasks at once—a critical skill for pilots.
Question 11: During the Airplane Tracking Test, what is the primary objective?
- To maintain a specific altitude
- To monitor engine performance
- To keep the aircraft symbol centered on the moving target (Correct answer)
- To perform navigation calculations
Correct answer: To keep the aircraft symbol centered on the moving target
In the Airplane Tracking Test, the primary objective is to continuously align the aircraft symbol with a moving target on the display. This task assesses a pilot's ability to maintain precise control and coordination. It simulates the demands of tracking an object or maintaining a specific flight path.
Question 12: Setting an altimeter to 29.92 inHg causes it to read which type of altitude?
- Density altitude
- Pressure altitude (Correct answer)
- True altitude
- Absolute altitude
Correct answer: Pressure altitude
Setting the altimeter to 29.92 inHg (the standard sea-level pressure) causes it to indicate pressure altitude, which is height above the standard pressure datum.
Question 13: A candidate is performing the Combined Tracking Coordination task. The horizontal target is drifting left, the vertical target is centered, and their pre-briefed target number "7" is announced. What is the most appropriate immediate sequence of actions?
- Move the joystick to re-center the vertical target before making other inputs.
- Ignore the auditory cue to maintain focus on the drifting horizontal target.
- Apply right rudder pedal to correct the horizontal target, then press the trigger.
- Press the trigger to respond to the auditory cue, then apply right rudder pedal. (Correct answer)
Correct answer: Press the trigger to respond to the auditory cue, then apply right rudder pedal.
The auditory cues are fleeting, time-sensitive events that must be responded to immediately, or the opportunity is lost. The tracking tasks are continuous and allow for a momentary delay in correction without an immediate failure. Therefore, the highest priority is to respond to the auditory number first, then correct the tracking error.
Question 14: What role does hand-eye coordination play in the Horizontal Tracking Test?
- It helps maintain vertical stability
- It reduces fuel consumption
- It assists in tracking the target accurately (Correct answer)
- It increases overall airspeed
Correct answer: It assists in tracking the target accurately
Hand-eye coordination is critical in the Horizontal Tracking Test as it allows the pilot to accurately perceive the target's position and translate that visual information into precise control inputs. This skill enables quick and correct adjustments to keep the target centered, reflecting real-world piloting demands for precise aircraft control.
Question 15: If a pilot makes a 45° turn to the left from a heading of 180°, what is the new heading?
- 270°
- 225°
- 135° (Correct answer)
- 90°
Correct answer: 135°
A pilot flying on a heading of 180° (South) makes a 45° turn to the left. A left turn means decreasing the heading value. Therefore, 180° - 45° = 135°. This calculation gives the new heading after the left turn.
Question 16: What is the opposite heading of 120°?
- 60°
- 210°
- 240°
- 300° (Correct answer)
Correct answer: 300°
To find the opposite heading, you add or subtract 180° from the given heading. If the heading is 120°, adding 180° gives 120° + 180° = 300°. This is the direct opposite direction on the compass rose.
Question 17: In the Northern Hemisphere, a magnetic compass will do which of the following when turning toward north?
- Oscillate rapidly back and forth
- Show the correct heading instantly
- Lead the actual heading
- Lag behind the actual heading (Correct answer)
Correct answer: Lag behind the actual heading
Due to magnetic dip in the Northern Hemisphere, the compass lags when turning toward north, requiring the pilot to stop the turn before the compass reaches the north indication.
Question 18: Which of the following best describes the primary purpose of the auditory processing speed components within the Test of Basic Aviation Skills (TBAS)?
- To evaluate a candidate's ability to quickly and accurately react to critical auditory information under cognitive load and amidst distractions. (Correct answer)
- To measure a candidate's musical aptitude and ability to discern different tones.
- To test long-term memory of aviation-related terminology presented verbally.
- To assess a candidate's ability to understand complex spoken instructions in a quiet environment.
Correct answer: To evaluate a candidate's ability to quickly and accurately react to critical auditory information under cognitive load and amidst distractions.
The auditory sections of the TBAS are designed to simulate a high-workload environment. They test a candidate's ability to process and respond to specific, critical auditory cues (like call signs or warnings) while simultaneously performing other tasks, which is a crucial skill for pilots.
Question 19: What is the most important control input when performing the Horizontal Tracking Test?
- Throttle adjustment
- Aileron deflection (Correct answer)
- Elevator trim
- Rudder pedal movement
Correct answer: Aileron deflection
In an aircraft, ailerons are the primary control surfaces used to induce roll, which in turn controls the horizontal (lateral) movement of the aircraft. Therefore, during the Horizontal Tracking Test, aileron deflection is the most important control input for keeping the target centered horizontally. Rudder pedals primarily control yaw, and elevator trim controls pitch.
Question 20: A pilot in IMC notices the altimeter, VSI, and airspeed indicator all appear frozen at their last values simultaneously. The most likely cause is:
- Gyroscopic precession in the gyro instruments
- A blocked static port (Correct answer)
- A total electrical system failure
- A blocked pitot tube
Correct answer: A blocked static port
All three instruments use static port pressure as a reference; a completely blocked static port would cause all three to freeze at their last indicated values.
Question 21: If the airspeed indicator fails to register any increase during a takeoff roll despite full engine power, the most likely cause is:
- A faulty altimeter
- An inoperative VSI
- A blocked pitot tube (Correct answer)
- A blocked static port
Correct answer: A blocked pitot tube
The pitot tube provides ram (dynamic) pressure to the airspeed indicator, so a blockage prevents the indicator from registering increasing airspeed.
Question 22: Your UAV is flying on a heading of 090° (East). From the UAV's perspective, which direction corresponds to the target located directly behind you?
- South
- West (Correct answer)
- East
- North
Correct answer: West
With a heading of 090° (East), the front of the UAV points East. The direction directly behind the UAV (180° opposite its heading) would be West (090° + 180° = 270°). Therefore, the target directly behind you is to the West.
Question 23: Which of the following is the most effective mental strategy for succeeding in the TBAS multitasking section?
- Mute the audio to eliminate distractions and maximize tracking scores.
- Prioritize the auditory task above all else, even if tracking performance suffers.
- Develop a scan or rhythm, continuously cycling attention between all required tasks. (Correct answer)
- Focus entirely on the joystick tracking, as it is the most complex task.
Correct answer: Develop a scan or rhythm, continuously cycling attention between all required tasks.
The key to the multitasking section is not to perfectly perform a single task at the expense of others, but to manage them all concurrently. An effective strategy is to develop a continuous, rhythmic scan, allocating brief moments of focused attention to each task in a cycle to ensure none are neglected.
Question 24: In a complex TBAS scenario, a candidate finds there is a direct trade-off in their performance: when they focus intently on the auditory channel to catch every target number, their tracking accuracy suffers, and vice-versa. This performance trade-off primarily demonstrates the:
- dynamic allocation of limited cognitive resources between competing tasks. (Correct answer)
- existence of separate, non-competing cognitive resources.
- inability to develop motor automaticity.
- static and unchangeable nature of an individual's cognitive capacity.
Correct answer: dynamic allocation of limited cognitive resources between competing tasks.
This scenario illustrates the dynamic allocation of attention. As the candidate shifts more cognitive resources to one task (listening), fewer are available for the other (tracking), leading to a performance trade-off. This shows that cognitive task management involves a constant, fluid balancing of a limited pool of resources.
Question 25: Your UAV is on a heading of 045° (Northeast). From your perspective in the UAV, the Southern target would be located generally...
- Ahead and to the right
- Ahead and to the left
- Behind and to the left
- Behind and to the right (Correct answer)
Correct answer: Behind and to the right
Your heading is Northeast (045°). South is at 180°. The relative direction is 180° - 045° = 135° to your right. This places the Southern target behind you and to your right.
Question 26: A pilot is recovering from an aerodynamic stall that has progressed into the initial phase of a spin. Correct recovery requires simultaneous and coordinated, but independent, inputs on the rudder and the control stick. This specific type of multi-limb coordination is most directly evaluated in which TBAS subtest?
- The Auditory Processing Speed subtest
- The standalone Two-Dimensional Tracking test
- The Spatial Orientation subtest
- The Combined Tracking Coordination subtest (Correct answer)
Correct answer: The Combined Tracking Coordination subtest
The Combined Tracking Coordination subtest requires the candidate to use their feet (rudder pedals) and their hand (joystick) to manage two separate tracking tasks at the same time. [6, 7] This directly mirrors the complex psychomotor skills needed for maneuvers like spin recovery, which require coordinated but distinct inputs from feet and hands to regain control.
Question 27: A candidate performing the TBAS multitasking subtest demonstrates near-perfect accuracy on the horizontal (pedal) and 2D (stick) tracking tasks but fails to respond to two of the three auditory target numbers. This performance most likely indicates a weakness in which area?
- A malfunction of the auditory response button.
- Poor understanding of the tracking tasks' instructions.
- Divided attention, with cognitive resources overallocated to the psychomotor tasks. (Correct answer)
- A fundamental hearing impairment.
Correct answer: Divided attention, with cognitive resources overallocated to the psychomotor tasks.
The candidate's success in the complex tracking tasks shows they understand them and have the necessary motor skills. However, their failure on the simpler auditory task when performed concurrently points to an inability to effectively divide their attention and manage the cognitive load of all tasks at once, a core skill the TBAS measures.
Question 28: A candidate is performing the Horizontal Tracking Control test and notices the target airplane, which was moving at a steady pace, suddenly speeds up. What is the most likely cause for this increase in difficulty?
- The test is approaching its time limit.
- It is a random event to test reaction time.
- The candidate has successfully kept the box over the target for a period of time. (Correct answer)
- The candidate has failed to track the target accurately.
Correct answer: The candidate has successfully kept the box over the target for a period of time.
The TBAS Horizontal Tracking subtest is adaptive; the difficulty, including the target's speed, increases as the test-taker demonstrates proficiency by successfully tracking the airplane.
Question 29: Which piece of equipment is used to provide control inputs for the Two-Dimensional (Airplane) Tracking subtest of the TBAS?
- Keyboard
- Rudder Pedals
- Joystick (Correct answer)
- Mouse
Correct answer: Joystick
The Test of Basic Aviation Skills utilizes specific hardware for its subtests. The Two-Dimensional Tracking task, also referred to as the Airplane Tracking test, requires the candidate to use a joystick to control the gunsight.
Question 30: In the more complex, combined-task portions of the TBAS, the Horizontal Tracking Control task is performed simultaneously with another activity. Which of the following tasks is most likely to be paired with it?
- Tracking a second target moving in two dimensions with a joystick. (Correct answer)
- Identifying aircraft silhouettes from a list.
- Solving complex mathematical equations.
- Answering true/false questions via keyboard.
Correct answer: Tracking a second target moving in two dimensions with a joystick.
A key feature of the TBAS is its assessment of multitasking. The Horizontal Tracking task (using rudder pedals) is combined with the Airplane Tracking Test, which requires using a joystick to follow a target moving across the entire screen.
Question 31: An aircraft is flying on a heading of 270° (West) and makes a 180° turn. What is the new heading?
- 90° (East) (Correct answer)
- 360° (North)
- 180° (South)
- 0° (North)
Correct answer: 90° (East)
An aircraft on a heading of 270° is flying West. A 180° turn means reversing direction. To find the new heading, you add or subtract 180° from the current heading. 270° - 180° = 90°. Therefore, the new heading will be 90°, which is East.
Question 32: In a scenario simulating a TBAS auditory test, a candidate hears the following sequence: 'Alpha... 7... Bravo... 5... Kilo...'. The target numbers are 3, 5, and 9. When should the candidate react?
- After the full sequence is complete
- Immediately after hearing '5' (Correct answer)
- Immediately after hearing 'Alpha'
- Immediately after hearing '7'
Correct answer: Immediately after hearing '5'
The instructions for this TBAS subtest require the candidate to respond as quickly as possible upon hearing a target stimulus. Since '5' is one of the designated target numbers, the correct action is to react immediately after it is announced.
Question 33: Which cognitive ability is most essential for preventing a gradual decline in performance throughout the entire duration of a long and repetitive TBAS multitasking subtest?
- Selective attention.
- Sustained attention (vigilance). (Correct answer)
- Divided attention.
- Spatial orientation.
Correct answer: Sustained attention (vigilance).
Sustained attention, also known as vigilance, is the ability to maintain concentration and focus over a prolonged period, especially on monotonous or demanding tasks. This is crucial for managing cognitive fatigue and preventing performance from degrading over the course of a lengthy test session.
Question 34: The Horizontal Tracking Control portion of the TBAS is fundamentally designed to assess a candidate's proficiency in which area?
- Psychomotor skills and foot-eye coordination. (Correct answer)
- Auditory processing and multitasking.
- Spatial orientation and map reading.
- Short-term memory recall.
Correct answer: Psychomotor skills and foot-eye coordination.
This subtest directly measures psychomotor abilities, specifically the fine motor skills required to coordinate foot movements with visual tracking tasks, which is a crucial skill for pilots.
Question 35: If the target moves up and to the left on the display, what should the pilot do?
- Apply right aileron and pull the stick back
- Apply left aileron and push the stick forward
- Apply left aileron and pull the stick back (Correct answer)
- Apply right aileron and push the stick forward
Correct answer: Apply left aileron and pull the stick back
If the target moves up and to the left, the pilot needs to move the aircraft symbol up and to the left to re-center it. To move up, the pilot pulls the stick back (elevator input). To move left, the pilot applies left aileron (roll input). Therefore, applying left aileron and pulling the stick back is the correct combined action.
Question 36: Which of the following is a common mistake pilots make during the Airplane Tracking Test?
- Maintaining too low an airspeed
- Focusing too much on altitude changes
- Ignoring the target's movement
- Using the rudder instead of the ailerons for horizontal adjustments (Correct answer)
Correct answer: Using the rudder instead of the ailerons for horizontal adjustments
A common mistake in the Airplane Tracking Test is misusing flight controls, specifically using the rudder instead of the ailerons for horizontal adjustments. Ailerons control the roll of the aircraft, which is essential for making precise lateral movements to track a target. Using the rudder, which primarily controls yaw, for horizontal tracking leads to inefficient and imprecise control, making it difficult to accurately follow the target.
Question 37: A candidate's TBAS results show high proficiency in the stand-alone listening and tracking tests, but a significantly lower score on the combined multitasking subtest where they are performed together. This specific pattern strongly suggests a deficit in:
- Motor skill coordination.
- Task comprehension.
- Cognitive load management. (Correct answer)
- Auditory processing speed.
Correct answer: Cognitive load management.
The candidate has proven they can perform each individual task well. The performance decline when the tasks are combined is a classic indicator of difficulty with managing cognitive load—the total amount of mental effort being used. The test is specifically designed to assess this ability to handle multiple concurrent demands.
Question 38: Which of the following correctly identifies the three distinct, simultaneous tasks required in the most complex version of the Combined Tracking Coordination subtest?
- Horizontal tracking with a joystick, vertical tracking with rudder pedals, and responding to visual cues.
- Horizontal tracking, vertical tracking, and solving on-screen math problems.
- Directional orientation, instrument cross-checking, and auditory memory recall.
- Horizontal tracking with rudder pedals, two-dimensional tracking with a joystick, and responding to auditory number targets. (Correct answer)
Correct answer: Horizontal tracking with rudder pedals, two-dimensional tracking with a joystick, and responding to auditory number targets.
The test explicitly combines three primary tasks: using rudder pedals to track a target horizontally, using a joystick to track another target in two dimensions (which includes the vertical axis), and responding to specific, pre-briefed numbers presented aurally.
Question 39: Which of the following real-world aviation scenarios is most accurately simulated by the specific skill set tested in the Combined Tracking Coordination subtest?
- Executing an emergency checklist from memory after an engine failure.
- Calculating fuel consumption and cross-referencing navigation charts during cruise flight.
- Maintaining a precise instrument approach path with control stick and rudder pedals while responding to Air Traffic Control instructions. (Correct answer)
- Performing a pre-flight inspection while verbally briefing a crew member.
Correct answer: Maintaining a precise instrument approach path with control stick and rudder pedals while responding to Air Traffic Control instructions.
The subtest mirrors the demands of a critical flight phase like an instrument approach, which requires continuous, fine motor inputs with both hands (joystick) and feet (rudder pedals) to maintain a flight path, while simultaneously processing and responding to critical auditory information from ATC.
Question 40: A pilot candidate is undergoing a TBAS subtest where they hear a series of letters and numbers. They are instructed to respond only when they hear one of the pre-briefed target numbers. Which of the following cognitive functions is LEAST directly measured by their speed and accuracy in this task?
- Spatial orientation (Correct answer)
- Auditory processing speed
- Reaction time
- Working memory
Correct answer: Spatial orientation
This auditory task primarily evaluates auditory processing speed, reaction time, and working memory (to remember the target numbers). Spatial orientation, which involves understanding one's position and direction relative to other objects, is not assessed in this purely auditory response test.
Question 41: If an aircraft is heading north (0°) and makes a 90° turn to the right, what will be its new heading?
- 180° (South)
- 270° (West)
- 90° (East) (Correct answer)
- 360° (North)
Correct answer: 90° (East)
In aviation, headings are measured clockwise from North (0°/360°). If an aircraft is heading North (0°) and makes a 90° turn to the right (clockwise), it will be facing East. Therefore, the new heading will be 0° + 90° = 90°.
Question 42: Which of the following scenarios accurately describes the main objective of the standalone Horizontal Tracking Control test?
- Use rudder pedals to keep a box centered over an icon that moves only left and right. (Correct answer)
- Listen for specific numbers while using a mouse to click on a moving box.
- Simultaneously use a joystick and rudder pedals to track two different targets.
- Use a joystick to keep a reticle on a target moving in all directions.
Correct answer: Use rudder pedals to keep a box centered over an icon that moves only left and right.
The core task of the Horizontal Tracking Control subtest is to use rudder pedals to control a box and keep it superimposed on a target moving strictly along a horizontal axis at the bottom of the screen.
Question 43: The requirement to use a joystick and rudder pedals for two different tracking tasks while simultaneously monitoring an auditory channel in the TBAS directly simulates which real-world pilot activity?
- Navigating using a paper chart while the co-pilot handles communications.
- Performing a pre-flight inspection while listening to a weather briefing.
- Calculating fuel consumption during a long-haul flight on autopilot.
- Manually flying an aircraft, monitoring instruments, and communicating with Air Traffic Control. (Correct answer)
Correct answer: Manually flying an aircraft, monitoring instruments, and communicating with Air Traffic Control.
This combination of multi-limb psychomotor control (flying the plane) and selective listening (communicating with ATC) is a direct parallel to the skills tested. Pilots must constantly divide their attention between controlling the aircraft's flight path and processing critical auditory information.
Question 44: A UAV is currently oriented on a heading of 270° (West). From the pilot's point of view, where is the Northern target located?
- Behind
- To the right (Correct answer)
- Directly ahead
- To the left
Correct answer: To the right
The UAV is heading West (270°). North (360°/0°) is 90 degrees clockwise, or to the right, of West. Therefore, from the pilot's perspective, the Northern target is to the right.
Question 45: In the Combined Tracking Coordination subtest of the TBAS, which controls are used to manage the two separate visual tracking tasks?
- Rudder pedals for horizontal tracking, joystick for vertical tracking. (Correct answer)
- Joystick for both horizontal and vertical tracking.
- Joystick for horizontal tracking, rudder pedals for vertical tracking.
- Rudder pedals for both horizontal and vertical tracking.
Correct answer: Rudder pedals for horizontal tracking, joystick for vertical tracking.
This subtest is designed to assess limb coordination by splitting the control axes between different inputs. The feet manage the horizontal target via rudder pedals, while the hand manages the vertical target via the joystick.
Question 46: What role does hand-eye coordination play in the Airplane Tracking Test?
- It reduces fuel consumption
- It increases overall airspeed
- It helps maintain proper engine performance
- It assists in tracking the target accurately (Correct answer)
Correct answer: It assists in tracking the target accurately
Hand-eye coordination is crucial in the Airplane Tracking Test because it allows a pilot to precisely translate visual information from the display into accurate control inputs. This skill enables the pilot to anticipate and react to the target's movements, making fine adjustments to keep the aircraft symbol aligned. Accurate tracking is directly dependent on this ability to synchronize visual perception with motor responses.
Question 47: During an in-flight emergency with multiple cascading system alerts, such as a master caution light, an engine fire bell, and a "low hydraulic pressure" voice alert, a pilot's ability to filter out non-critical alerts and focus on the most immediate threat is analogous to which TBAS task?
- Maintaining a target within the tracking box in the Horizontal Tracking test
- Simultaneously managing joystick and rudder pedal inputs in the Combined Tracking test
- Responding to pre-briefed target numbers amidst distracting auditory information (Correct answer)
- Determining aircraft orientation from the attitude indicator in the Spatial Orientation test
Correct answer: Responding to pre-briefed target numbers amidst distracting auditory information
The auditory processing speed test directly measures selective attention—the ability to focus on relevant stimuli (target numbers) while ignoring irrelevant ones (distractor letters and numbers). This cognitive skill is crucial for managing multiple alerts during an emergency, prioritizing the most critical warning, and avoiding distraction. [19, 21]
Question 48: Without a visible natural horizon (at night or in clouds), why can a pilot not reliably sense aircraft attitude without instruments?
- Magnetic interference distorts spatial awareness
- Vision becomes the dominant and accurate sense in darkness
- Aircraft controls become less responsive in IMC
- The vestibular (inner ear) system produces false or misleading attitude cues (Correct answer)
Correct answer: The vestibular (inner ear) system produces false or misleading attitude cues
The vestibular system is easily deceived by sustained turns and accelerations, producing false sensations of level flight, which is why instrument reliance is critical in IMC.
Question 49: What feedback mechanism is essential for a pilot to perform well in the Airplane Tracking Test?
- Visual feedback from the display (Correct answer)
- Verbal instructions from the instructor
- Audio cues from the aircraft
- Tactile feedback from the control stick
Correct answer: Visual feedback from the display
Visual feedback from the display is essential for a pilot to perform well in the Airplane Tracking Test because it provides real-time information on the aircraft symbol's position relative to the target. This immediate visual input allows the pilot to assess their performance, identify any deviations, and make necessary control adjustments. Without clear visual cues, effective tracking and accurate course correction would be impossible.
Question 50: An aircraft is heading on a bearing of 330° and turns left 90°. What is the new heading?
- 0°
- 90°
- 240° (Correct answer)
- 60°
Correct answer: 240°
An aircraft on a bearing of 330° turns left 90°. A left turn means subtracting degrees from the current heading. So, 330° - 90° = 240°. This calculation provides the new heading after the specified turn.
Question 51: During the Horizontal Tracking test, the target airplane is moving steadily towards the left side of the screen. Besides hitting the screen edge, what other event will cause the target to change direction?
- A random timer expiring.
- The introduction of an auditory distraction.
- Sustained successful tracking of the target for several seconds. (Correct answer)
- The candidate pressing down on both rudder pedals at once.
Correct answer: Sustained successful tracking of the target for several seconds.
The test is programmed so that if a participant successfully keeps the tracking box over the airplane for multiple seconds, the airplane will change direction, testing the candidate's reactive abilities.
Question 52: Which control input is most commonly used to keep the aircraft symbol centered on the target?
- Aileron and elevator inputs (Correct answer)
- Rudder pedal movement
- Flap adjustment
- Throttle adjustment
Correct answer: Aileron and elevator inputs
To keep the aircraft symbol centered on a moving target, a pilot typically uses both aileron and elevator inputs. Ailerons control roll for horizontal adjustments, while elevators control pitch for vertical adjustments. Coordinated use of these controls allows for precise two-dimensional tracking of the target.
