After loss of pitot input the IAS "red-x'd" on my dual GI 275 installation. I had the opportunity to test various failure considerations I had been thinking about to evaluate how the AHRS (attitude indicator) would perform. Would it "red-x", tumble or drift?
The failures were equivalent of having lost alternator and battery and therefore shutting down the panel as well as causing the pitot tube to freeze in IMC. Would the GI 275 AI survive?
