I get the nuisance alarm when I do a full stall 3 point landing. When I wheel land and gradually lower the tail I never get the alarm.

Default NO Alarm

taking off or landing. I do some transition training and stalls are part of the package. The AOA alarm is set to go off at the top of the yellow, which is does and is just an instant before the stall buffet. A friend in the adjacent hangar has a 7A with a D10A. It also appeared to function the same as mine during his flight review.

Best regards,

Bill

Brian,
In my experience, most people do not get this alarm. I've ridden in plenty of Dynon AoA equipped airplanes with working audio alerts and have never experienced this. It seems to be somewhat dependent on the airplane and the calibration.

7 planes so far in this little thread alone.

I understand why it is the way it is and live with it....

The silence button is just a suggestion.

Mine does not do it every landing. Only on three pointers with a good headwind. I doubt trikes ever have this issue once the nose wheel is on the ground.

Default Dynon aoa nuisance alarm

Just installed and calibrated my new Dynon AOA system. Works great except that I cannot configure it so that the alarm stops below my "min speed" setting.
It stays on throughout the rollout which is very annoying to say the least!
I noticed a few comments regarding tailwheels, and am thinking my T/W RV8
wing never leaves the stall regime because of its aoa on the ground after a 3 point landing.
Dear Dynon...please design a kill switch for the audio alarm!

I have never heard of this issue before. I have the same configuration as Rob. Never had it occur once.

I can only assume it is a configuration issue. My AOA is configured for a deeper stall? I definitely get into the yellow but can't recall if I ever flare into the red at least not consistently.

I've never experienced the problem. Mine comes on just before touchdown and goes off when solidly on the ground. 90% of my landings are 3-point. D10A with homemade pitot/AOA. I don't see how the homemade pitot could make a difference.

Both SkyView and the D10/D100 have low speed inhibit settings. Page 4-17 of the SkyView install manual, and page 7-31 of the D10A manual.

The following is quoted from the D10 Install manual, page 7-31:

"While in the menu, press MINSPD to configure the minimum airspeed at which an AOA alarm can occur. Anytime airspeed is below the MINSPD value, AOA alarms will not occur; anytime it is above the MINSPD value, alarms can occur. If the AOA alarm is already sounding as airspeed falls below this threshold, it will continue to sound until the high AOA condition is resolved."

Unfortunately, this will not resolve the problems discussed in this thread. The software feature described in the last sentence quoted above is what causes the alarm to continue to sound when taxiing a tailwheel aircraft in a moderately strong breeze.

Dynon....we need an ACK button to silence the alarm when it becomes a nuisance. Thank you.

It is amazing to me how hard it is sometimes to get a point across of these forums. This has been discussed for years now and someone from Dynon totally missed the point.

Sam got it though!

As usual the point is buried in the details.
