Nope, of course not, the AI is just another unreliable instrument like all the others.danerazz wrote:Dave Krall CFII SEL SES wrote:Yeah right, then I could wonder if the efing AoA indicator was working and reporting properly instead.
I've actually had an audio/visual one installed in the FC from the beginning, just never use it and can't imagine relying on it for stalls or landings, but some of the other things, maybe....
...because the airspeed indicator is infallible? at all weights? in all configurations?
The certified aircraft with stall warning indicators are essentially AOA sensors on the leading edge. That little tab that moves is just calibrated to move at a given AOA, which happens to be at a given airspeed in a given configuration/weight. Same with the Cessna "sucker" horns. People have been relying on those for decades. The new AOA systems work exactly the same way, they just present the information in different ways.
Yep, people have been relying on them for decades, and that unfounded reliance continues to be a substantial factor in a good chunk of accidents. Instruments should just be a cautionary reinforcement and backup to the main "instrument" operating the aircraft.
