ANGLE OF ATTACK PROBE HEAT - DESCRIPTION AND OPERATION
______________________________________________________
General
_______
A. Two angle of attack (AOA) probes (one on each side) are electrically heated to prevent erroneous readings due to ice conditions. AOA probe heat system components include: AOA probes, the auxiliary annunciator panel, and the miscellaneous test panel.
B. System electrical power comes from the 28v dc buses, and the 115v ac buses. Circuit breakers are on overhead circuit breaker panel P11, and main power distribution panel P6.
