I have a very simple question and I've reviewed virtually all of the posts in both threads and not found an answer.
Of the pilots' flight instrument displays, what do they lose if all 3 pitot sources fail? Do they lose everything including bank, turn and vertical airspeed or do they just lose the airspeed display?
Grumpyoldgeek:
Airspeed.
Bank & Turn rely on IRU ATT data, basically gyros.
Vertical Speed & Altitude readouts come from the Static port data via the Air Data computers.
In my opinion, the pitot would be the most likely lost sensor set. The static ports are not facing the airstream and would not collect ice particles.
