A320 FPV
Can anyone help with this conundrum please?
In the context of UAS, the FCTM tells us that if altitude info is suspect not to use the FPV. My understanding has always been (wrongly perhaps) that the FPV is purely inertial. In the sim, with all ADRs switched off, it still works.
Also, it tells us that in ac without the BUSS, we have to keep at least 1 ADR ON to allow stall warning - which is AoA related. Why do we need an ADR to allow stall warning.
As usual the FCOM DSC is next to useless.
