Setting Aoa Upper Limit - uAvionix AV-30-C Manual

11.4 Setting AoA Upper Limit

The objective is to set the upper AoA limit such that the first red bar
illuminates at roughly the same time as the on-set of the aircraft's stall
warning system.
To find the upper limit, the following procedure is recommended:
• Ensure the AV-30-C is in INSTALLATION MODE (see Section 0).
• Select a safe altitude suitable for stalls, minimum 1,500 feet AGL.
• Aircraft Configuration:
o Airspeed V
o Flaps 20
o Power as required
o Stable flight conditions
• Slowly reduce speed at a rate of 1 knot per second and maintain a constant
altitude.
• Monitor the displayed AoA as the aircrafts angle of attack increases.
• If the aircrafts stall-warning occurs prior to the indicator reaching the first red
bar, the upper AoA limit needs to be numerically lowered to coincide with the
aircrafts stall-warning point.
• If the aircrafts stall-warning occurs after the indicator has reached the first red
bar, the upper AoA limit needs to be numerically raised to coincide with the
aircrafts stall-warning point.
•
Utilize the Setup Menu section and associated procedure in this manual to
adjust the upper limit as required.
•
Repeat the above procedure as needed and to ensure consistency.
