ATC Airport Operations 1 — Questions and Answers
Question 1: What is a Land and Hold Short Operation (LAHSO)?
- An operation where an aircraft lands and holds short of an intersecting runway or taxiway (Correct answer)
- An operation where an aircraft holds short of the runway before landing
- A procedure where aircraft taxi to the runway hold short position
- A clearance for an aircraft to land and immediately depart again
Correct answer: An operation where an aircraft lands and holds short of an intersecting runway or taxiway
LAHSO allows an aircraft to land and stop before reaching an intersecting runway or taxiway, enabling simultaneous use of intersecting runways.
Question 2: What does a flashing white light signal from the control tower mean to an aircraft on the ground?
- Return to starting point on the airport (Correct answer)
- Cleared to taxi
- Stop immediately
- Exercise extreme caution
Correct answer: Return to starting point on the airport
A flashing white light signal from the tower to an aircraft on the ground means return to starting point on the airport.
Question 3: What is a displaced threshold?
- A threshold that is not at the beginning of the runway pavement but is marked further down the runway (Correct answer)
- A temporary runway threshold used during construction
- The threshold of a secondary runway displaced from the primary
- A threshold that is offset to one side due to obstacles
Correct answer: A threshold that is not at the beginning of the runway pavement but is marked further down the runway
A displaced threshold is located at a point on the runway pavement other than the beginning, with the area before it available for takeoff but not landing.
Question 4: What is the purpose of Runway End Identifier Lights (REIL)?
- To provide rapid and positive identification of the approach end of a runway (Correct answer)
- To illuminate the entire runway surface for night operations
- To mark the touchdown zone for precision approaches
- To indicate the runway is closed for maintenance
Correct answer: To provide rapid and positive identification of the approach end of a runway
REILs consist of a pair of synchronized flashing lights at the runway threshold to help pilots quickly identify the runway approach end.
Question 5: What does a 'cleared for the option' clearance allow a pilot to do?
- Make a touch-and-go, stop-and-go, full stop landing, or missed approach (Correct answer)
- Choose any runway for landing
- Land on any available taxiway if the runway is occupied
- Conduct a practice ILS approach without actually landing
Correct answer: Make a touch-and-go, stop-and-go, full stop landing, or missed approach
A 'cleared for the option' clearance permits a pilot to make a touch-and-go, stop-and-go, full stop landing, or a missed approach at the pilot's discretion.
Question 6: What color are airport taxiway edge lights?
- Blue (Correct answer)
- Green
- White
- Yellow
Correct answer: Blue
Taxiway edge lights are blue and define the edges of the taxiway during night operations or low visibility conditions.
Question 7: What is the standard traffic pattern altitude for propeller-driven aircraft at an airport without a control tower?
- 1,000 feet AGL (Correct answer)
- 500 feet AGL
- 1,500 feet AGL
- 2,000 feet AGL
Correct answer: 1,000 feet AGL
The standard traffic pattern altitude for propeller-driven aircraft is 1,000 feet above ground level (AGL) unless otherwise specified.
