ARS Aircraft Towing and Pushback Operations 1 — Questions and Answers
Question 1: What is the primary communication method between the cockpit crew and the ground crew during pushback operations?
- Hand signals from the wing walker
- Interphone/headset communication (Correct answer)
- Radio communication on the tower frequency
- Visual flag signals from the tug driver
Correct answer: Interphone/headset communication
Interphone/headset communication provides direct, clear two-way contact between the cockpit and the ground crew lead throughout the pushback.
Question 2: Before connecting a towbar to an aircraft, what must be verified?
- Ground power is disconnected from the aircraft
- The aircraft engines are in idle
- The towbar is rated and certified for that specific aircraft type and weight (Correct answer)
- Passenger boarding is complete
Correct answer: The towbar is rated and certified for that specific aircraft type and weight
Using a towbar not rated for the aircraft type and weight risks structural failure of the towbar or nose gear during towing.
Question 3: What is the maximum towing speed typically permitted for aircraft on an airport ramp?
- 15 mph
- 10 mph
- 25 mph
- 5 mph (walking pace) (Correct answer)
Correct answer: 5 mph (walking pace)
Most airline and airport ground operations manuals limit aircraft towing to 5 mph (walking pace) to maintain control and allow for safe stopping distances.
Question 4: At what point during pushback should aircraft parking brakes be set?
- Throughout the entire pushback operation
- Only before engines are started
- After the pushback is complete and the towbar is disconnected (Correct answer)
- Before the tug connects to the nose gear
Correct answer: After the pushback is complete and the towbar is disconnected
Parking brakes are set after the pushback is complete and the towbar is disconnected, securing the aircraft in its final parked position.
Question 5: What is the purpose of a breakaway coupling on an aircraft towbar?
- To allow rapid towbar removal during routine gate turns
- To intentionally fail before the nose gear structure if excessive force is applied (Correct answer)
- To connect two towbars in tandem for heavy aircraft
- To lock the towbar permanently to the nose gear
Correct answer: To intentionally fail before the nose gear structure if excessive force is applied
A breakaway coupling is a sacrificial safety device designed to fail before the aircraft's nose gear structure in an overload situation, preventing costly structural damage.
Question 6: During a pushback operation, who has the authority to immediately stop the operation?
- The airline operations control center only
- Air traffic control only
- The ramp supervisor only
- Either the cockpit crew or the ground crew lead (Correct answer)
Correct answer: Either the cockpit crew or the ground crew lead
Both the cockpit crew and the ground crew lead have equal authority to call an immediate stop if either identifies a safety hazard during pushback.
Question 7: What must be done before towing an aircraft across an active taxiway or intersection?
- Notify the destination gate agent and wait for acknowledgment
- Obtain ATC clearance and post wing walkers as required (Correct answer)
- Sound the tug horn three times to warn other vehicles
- Stop and allow all other ground vehicles to clear first
Correct answer: Obtain ATC clearance and post wing walkers as required
ATC clearance is required before crossing active taxiways or runways, and wing walkers are typically required to guide the aircraft safely through intersections.
