AFOQT - Air Force Officer Qualifying Aviation Information Concepts Questions and Answers 1 — Questions and Answers
Question 1: An aircraft is in straight-and-level flight. To make the aircraft roll to the right, the pilot must manipulate the controls to...
- lower the left aileron and raise the right aileron. (Correct answer)
- lower the elevators.
- deflect the rudder to the right.
- raise both ailerons simultaneously.
Correct answer: lower the left aileron and raise the right aileron.
Ailerons control the aircraft's roll about the longitudinal axis. To roll right, the left aileron is lowered to increase lift on the left wing, and the right aileron is raised to decrease lift on the right wing, causing the aircraft to bank to the right.
Question 2: Which of the following best describes the primary function of an aircraft's empennage?
- To generate the majority of the aircraft's lift.
- To house the main landing gear and fuel tanks.
- To provide stability and control for pitch and yaw. (Correct answer)
- To mount the engines and generate thrust.
Correct answer: To provide stability and control for pitch and yaw.
The empennage, or tail assembly, consists of the vertical stabilizer (fin) with its rudder and the horizontal stabilizer with its elevator. These surfaces work together to provide aerodynamic stability and control the aircraft's pitch (up and down motion) and yaw (side-to-side motion).
Question 3: On an airport runway, a series of large white arrows pointing down the centerline leading to a wide, solid white line across the runway indicates a:
- blast pad.
- displaced threshold. (Correct answer)
- stopway.
- closed runway.
Correct answer: displaced threshold.
This marking indicates a displaced threshold. The area leading up to the solid white line (the displaced threshold) can be used for taxiing and takeoff, but not for landing. Aircraft must land beyond this line.
Question 4: In aerodynamics, what is the 'angle of attack'?
- The angle between the aircraft's nose and the horizon.
- The angle of the wings relative to the fuselage.
- The angle at which the aircraft is climbing or descending.
- The angle between the wing's chord line and the relative wind. (Correct answer)
Correct answer: The angle between the wing's chord line and the relative wind.
The angle of attack is a critical aerodynamic concept defined as the angle between the chord line of an airfoil (a straight line from the leading edge to the trailing edge) and the direction of the oncoming air, known as the relative wind. It is a primary factor in determining the amount of lift generated.
Question 5: What is the primary purpose of the tail rotor on a conventional single-rotor helicopter?
- To provide additional lift during takeoff.
- To steer the helicopter in forward flight.
- To counteract the torque produced by the main rotor. (Correct answer)
- To function as a secondary propulsion system.
Correct answer: To counteract the torque produced by the main rotor.
According to Newton's third law, as the engine turns the main rotor, an equal and opposite turning force (torque) is exerted on the helicopter's fuselage, causing it to spin in the opposite direction. The tail rotor produces thrust to the side to counteract this torque, keeping the helicopter stable.
Question 6: In the context of the four forces of flight, which force directly opposes drag?
- Lift
- Weight
- Thrust (Correct answer)
- Gravity
Correct answer: Thrust
The four fundamental forces acting on an aircraft in flight are lift, weight, thrust, and drag. Thrust is the forward-acting force generated by the power plant/propeller, which opposes or overcomes the rearward-acting force of drag.
An aircraft is in straight-and-level flight.
