Standby Instruments ADIRS A320
Folks,
after reading all the stuff im totally confused. Cann somebody explain me in easy words, how the ADIRS System (ADR, IR, STBY) works in the A320? I always thought that we have 3 ADRs and 3 IRs. One Fails, we can Switch them to the side where it is lost. Do the ADR3 or IR3 give Inputs to the STBY ISIS? I thought it is a stand alone platform but the Manual obviously says that it gets Input from ADIRS 1 and 3?
Some easy Explanation would help and thanks so much!
