Garmin, are you listening? I agree that's an excellent redundancy. I have a PFD /MFD input switch between my Aspens and the autopilot. If the PFD goes bad I can switch to reversionary mode and then switch the A/P source to MFD and the autopilot carries on like nothing happened. 2 Quote

They still have a single point of AP failure, as they all do. The Sturn 55 was a great AP in "the day" and sure beats not having one. Today, the Garmin is just that much better and not subject to the electric TC spinning up/failures of the older tech. A shame Genesys doesnt make the 3100 available as a drop in replacement for the 55 I thought I trademarked "Sturn 55X" when I was transitioning from a very precise KFC150 to a very imprecise STec 55X in a new Piper Mirage in 2000. I have to admit after i finally spent a day with Stec in Mineral Wells the 55X was much better, but still not like an attitude based autopilot. Quote

Anyone know first hand of such? The challenge with the 737 Max experience... There were at least two different versions of the AP system available to the plane buyer... The lower cost version had a single AOA sensor... The higher cost version had at least two sensors, possibly a third, as a tie-breaker.... So... The question is... Ever have an AOA sensor fail... what happened next? External sensors live in a pretty harsh environment... their next failure can be right around the corner... Before getting on a Max flight... ask the pilot how many AOA sensors are on the plane... and if his training is up to date.... PP musings only, not a plane manufacturer... Best regards, -a- Quote

GeeBee Posted October 21, 2020 Report Posted October 21, 2020 It is part of the FAA directive to fix it. Quote
