Setting Aoa Upper Limit - uAvionix AV-30-E Pilot's Manual

The figure below shows how the configured upper and lower limits are
mapped onto the color coded AoA indication.

11.3 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 the aircrafts stall warning occurs.
To set the upper limit, the following procedure is recommended:
• At a safe altitude suitable for stalls, configure the aircraft for the
normal base-to-final turn (typically gear and partial flaps
extended).
• Slowly reduce speed and maintain a constant altitude,
monitoring the display 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
