FAA Airline Transport Pilot (ATM)Aircraft Performance and Weight and BalanceMedium
A dispatcher is checking whether the landing climb requirement limits the maximum landing weight at the destination airport. Per 14 CFR Part 25, the landing climb gradient is demonstrated in which configuration and engine condition?
- AOne engine inoperative, gear up, approach flaps, at go-around thrust
- BAll engines operating, takeoff flaps, gear retracted, at takeoff thrust
- CAll engines operating, landing flaps extended, gear down, at go-around thrust
- DOne engine inoperative, clean configuration, at maximum continuous thrust
Show answer & explanationAnswer & explanation
Correct answer: C. All engines operating, landing flaps extended, gear down, at go-around thrust
14 CFR 25.119 requires the landing climb gradient be demonstrated with all engines operating, landing gear and flaps in the landing configuration, and engines at go-around thrust, representing a balked landing with all engines available. The minimum required gradient is 3.2%.
Why the other options are wrong
- A. This describes the separate approach climb (OEI) requirement, not the landing climb.
- B. Takeoff flaps and takeoff thrust describe the takeoff phase, not the landing climb requirement.
- D. Clean configuration with OEI does not match the landing-configuration landing climb test.
Landing Climb Gradient
A Part 25 requirement (25.119) demonstrating a minimum climb gradient with all engines operating, gear down, and landing flaps extended, at go-around thrust.
- All engines operating (unlike approach climb which is OEI)
- Landing gear down, landing flaps extended
- Minimum required gradient is 3.2%
Memory trick: Landing climb = 'Landed config, all engines Lively.'
