What is the difference between a 'hard landing' and a normal landing from a systems perspective?
Answer: Hard landings may impose loads exceeding design limits, requiring mandatory structural inspection
A hard landing may impose vertical loads exceeding the aircraft's design limits, requiring engineering inspection before further flight per the maintenance manual.
What is the primary reason for conducting a weight and balance check before flight?
Answer: To ensure the center of gravity remains within approved limits for safe flight
Weight and balance ensures the aircraft's center of gravity is within the approved envelope, which is essential for maintaining stable and controllable flight.
What does 'pressurization differential' refer to in aircraft operations?
Answer: Difference in air pressure between the cabin interior and the outside atmosphere
Cabin pressurization differential is the difference between the internal cabin pressure and the external ambient pressure, measured in PSI.
What operational limitation typically applies when an aircraft's engine anti-ice system is inoperative?
Answer: Flight into known or forecast icing conditions is prohibited
An inoperative engine anti-ice system prohibits flight into known or forecast icing conditions per MEL requirements and airworthiness limitations.
What does the 'autobrake' system on a large jet aircraft automatically adjust during the landing rollout?
Answer: Brake hydraulic pressure to maintain a selected deceleration rate
The autobrake system continuously adjusts hydraulic brake pressure to maintain the pilot-selected deceleration rate throughout the landing rollout.
What is the purpose of an aircraft's flight data recorder (FDR)?
Answer: Record flight parameters to aid in accident and incident investigation
The FDR records hundreds of aircraft parameters such as altitude, airspeed, and control inputs, and is used to reconstruct events during accident investigations.
Which type of aircraft engine oil system component removes heat from the oil before it re-enters the engine?
Answer: Fuel-cooled oil cooler (FCOC)
The fuel-cooled oil cooler uses cool fuel as the heat exchange medium to reduce oil temperature before the oil is recirculated through the engine.
