For those airplanes that have less than 2" of clearance in the wing inside the inspection cover and want a heated probe, this is an option for you (i.e. Bonanza, etc). The heated probe has a built in heater that minimizes the potential for ice build up on the leading edge of the probe.
Built in heater of 12VDC or 24VDC
Requires a dedicated 10 amp breaker or fuse, switched, due to 7.167 Amp draw
It is a drop in replacement and can be used or upgraded in the existing Alpha Systems AOA mounting plate
