PROBES HEAT - DESCRIPTION
A330/A340 FLEET DSC-30-50-10 P 1/2
FCOM 19 AUG 10
DESCRIPTION
Applicable to: ,
Electrical heating protects :
‐ pitots.
‐ static ports.
‐ Angle-Of-Attack (AOA) probes.
‐ Total Air Temperature (TAT) probes.
Three independent Probe Heat Computers (PHC) automatically control and monitor :
‐ Captain probes
‐ F/O probes
‐ STBY probes
They protect against overheating and indicate fault.
The probes are heated :
‐ automatically when at least one engine is running, or in flight
‐ manually, when the flight crew switches ON the PROBE/WINDOW HEAT pushbutton switch.
On the ground, the TAT probes are not heated and pitot heating operates at low level (the
changeover to normal power in flight is automatic).
