the best use of GPS Altitude so far: B.U.S.S
I forgot what the achronym means!
but it is a new gadget available in the airbus family.
When switching off all three ADRs, the PDFs speed tape and altitude tape are substituted by an angle of attack tape (similar to a fast slow indication) and a GPS altitude indication.
With this BUSS you are not afraid of unreliable speed anymore. You will not break the airplane into pieces, you can keep it within the envelope.
But I still have a question: In the unreliable speed procedure for airbus we have to level off. However we cannot trust the altimeter, since static probes could be the source of the unreliable speed indication. So GPS altimeter comes in very handy, then, but żIs it reliable to fly V/S zero?
and what if you don't have a GPS at all? but that is for another thread
ATCAst thanks for the likns and info!
