AoA Probe
Normally the AoA will produce audible “beeps” as the airplane approaches a stall. If no AoA
audio alerts are heard approaching a stall, perform the following checks:
1. Verify audio is heard for other SkyView HDX system messages. If audio is heard for other
messages, then there may be a problem with the pneumatic tube from the AoA probe to
the ADAHRS module.
2. Remove AoA probe and make sure the pneumatic tube is securely attached.
3. Check for blockage of AoA probe.
4. If Steps 1-3 pass, inspect the AoA connector going into the AoA port on ADAHRS module.
