How does radio altimeter work?
The purpose of the Radio Altimeter (RA) is to measure the absolute height of the aircraft above the terrain. This is accomplished by transmitting a signal to the ground, see Fig 5AI 3.1, and processing the received signal into analog voltage proportional to the height.
What does SRS mean on takeoff?
SRS- Speed Reference system. It means that the Flight director pitch guidance will be based on speed, usually V2+10 knots. It is useful as a guide for your pitch on initial climbout. RWY- this is your lateral guidance during takeoff.
What does the flight augmentation part of the FMGC do?
The flight augmentation part provides flight envelope computation, maneuvring speed computation, windshear detection, α-floor protection and various yaw functions. The FMGCs normally receive information from “on-side” sensors, and communicate between themselves to validate data.
What happens to the autothrust after a FCU failure?
A single failure will have very little effect. A double FCU failure will lead to the loss of both autopilots, both flight directors and the autothrust. The autothrust will revert to thrust locked until the thrust levers are manually moved. All targets are lost on the PFD.
What is the name of the flight management computer?
Main processing is carried out by two identical Flight Management Guidance Computers (FMGC) which normally work in tandem. Together they are known as the flight management guidance system (FMGS).
What does FMA lateral mode Annunciation look like?
FMA lateral mode annunciation are HDG and TRACK respectively. The FCU displays HDG and V/S legends when in attitude mode and TRK and FPA legends when in flight path mode. The altitude window contains the next applicable clearance altitude selected by the crew with the target altitude knob and is never dashed.
