Calibration instructions for ASPEN AOA

[Oscar Avalle]

I am looking for the calibration instructions for my ASPEN AOA. The dealer provided them to me, but unfortunately I misplaced them. So if anybody can help me... thank you

From personal experience go on a calm smooth day. It is very hard to keep the required speeds, heading and altitude required to complete the calibration. I also seems to work best if you are close to max weight. Also bring someone along to keep an eye out for traffic you will be spending several minutes watching instruments.

Do you calibrate it with flaps up or flaps down?. The question I have is if it’s calibrated with the flaps up how do you know what the real stall speed is with flaps down?

The procedure calls for calibration both clean and flaps/gear down. There are two pointers, one for each calibration setting.

Mine (installed by a defunct avionics shop for the previous owner) is way out of calibration; normal approach is way into the cross-hatch stall warning area. Sooner or later I will try to correct it, but the display on a single display EFD1000 is so small that it doesn't really seem that useful to me.

Thanks for sharing the instructions with me. The procedure is easy and well explained. I calibrated the indicator today. However, I have to admit the indicator in a PFD is rather small. So it is not very user-friendly and easy to read. But it is useful once you get used to it.

What speeds did you use for the AOA calibration? 

 

AOA Calibration

Min Vis AOA 1.5 x VSO (100 KIAS)

Stall Warning AOA  at Stall

Caution Alert AOA 1.1 x VSO (Stall + 5 KIAS)

Approach Target AOA 1.3 x VSO (500FPM Short Final Speed 75 KIAS)
