Unreliable Speed A320
Hello friends,
quick one on this. We had the scenario in January which was: ADR 1 totally inop, ADR 2 speed unreliable and altitude ok, ADR3 inop. So the checklist asks for identifying the affected ADR. Ok, all three are actually unreliable. BUT ADR2 has a valid Altitude which can be used and makes it much easier. So why does Airbus say you have to switch it of? Because of the warnings related to the unreliable speed on adr2? Otherwise you could keep it running?
Thanks so much
