Airbus A320 - Automatic Flight
Regarding metric altitudes, which of the following statements is true?
On ground the flight crew arms A/THR by pushing the A/THR pb on the FCU when the engines are not running, or by setting the thrust levers at the FLX or TOGA detent when the engines are running.
The A/THR is active when it controls thrust or speed. The position of the thrust lever determines the maximum thrust that the A/THR system can command (except in alpha floor condition).
When the flaps are extended, the FACs automatically set the rudder deflection limit at the low-speed setting (maximum authorized deflection).
When the SLATS are extended, the FACs automatically set the rudder deflection limit at the low-speed setting (maximum authorized deflection).
How long does a normal IR alignment take?
Fast alignment is used to refine a position when time is limited. A fast alignment takes approximately 30 seconds.
The SRS mode engages automatically when the thrust levers are set to the TOGA or FLX/MCT detent, providing:
With the A/THR engaged, it is possible to achieve more thrust than MAX CLB thrust.
If hand flown to VLS or VMAX with the autothrust engaged, which mode will it automatically revert to?
When alpha floor protection is triggered it automatically commands TOGA thrust on both engines, regardless of the position of the thrust levers.
Alpha Floor Protection is available from lift-off until the aircraft reaches 100 feet RA on the approach to landing.
