Audible beep when accelerating

[JimD]

During the takeoff roll, above 10 knots or so, a beeping noise is heard over the headsets. It is a new installation of a single Skyview display with a PMA8000G and IDF 440 and remote Dynon com panel. I have not been able to isolate it to a specific instrument while in flight.
Has anyone had this issue and what should I be looking at to solve the issue?
I'm a first time poster and apologize for any initial missing information.

Do you have the AOA (Angle Of Attack) system active? Does the beeping continue through the rotation and then fade as you fly off the runway after a few seconds?

 

[JimD]

I do have the AOA system installed, and I believe it is always active.
the beeping will continue for about 20-25 minutes into the flight.

Have you calibrated your AoA?

 

[JimD]

The installer said that they did the calibration.
Do I need to redo the process?

 

[PaulSS]

I would in the first instance, as that will cancel one potential source of the continued beeping. It only takes a few stalls to get it done, so is an easy thing to take care of.

Calibrating the AOA is a good idea on any plane new to you so you know it was done properly but bear in mind there is a separate setting for the minimum airspeed at which the AOA alert is active. The installation instruction recommend setting that to a number 5-10 knots below actual stall so you will not get warnings on the ground as is currently your experience.

Thanks everyone. I’ll go through the calibration process and see if it takes care of the issue. And will report back.
