The AoA system is part of the ADHARS system and is powered by the backup battery. The question here is whether I get aural tones if the radio is not powered.
All this leads to this potential conclusion: If you are expecting to use the AoA system or stall warning tone to assist you in a minimum energy forced landing, you may not have them if you secure the master prior to touch down.
No, it wont. But that doesn't mean you don't have AOA info.
The AOA depiction on the screen will still be active. The visual stall warning indicator will as well. You just wont have aural info.
Practically speaking, I don't think I would be hawking anything but the airspeed. Head out of the cockpit mostly. Cant see myself even glancing at the "micro" AoA display.
Your scan must be more comprehensive than mine Scott. It is easier for me to see it when I'm full screen and don't have the map up. And by see it, I mean "process" it. I've gotten used to flying the tones. Last time I see the airspeed is just prior to crossing the threshold. At solo weights, that's usually about 50 kts, AoA tones kick in at 47 kts the way I have it set up. Thanks to the Dynon data down load capability, I can see my touch downs have been consistently 44-42 kts about the time the stall warning starts whining. By the time I pass the 1000 ft marker, I've been in taxi mode for a while. I think the aural tones have spoiled me.
