re from captain87
Clandestino,
thank you very much for your answer that is what I expected to know.
In fact there aren't procedures dealing with a Triple IRS Failure in PRH.
With the loss of three IRS, are the ADIRS still capable of providing AD (Air Data Informations) without IRS ? ... Are both GPS's still using their MMR (Multi Mode Receivers) to "supply" the ADIRS ?
That was I asked in this thread. Thank you at all.
