b. Low pressure is detected
In what position do the Wing and Engine Anti-Ice valves fail if electrical power is lost?
(FCOM-DSC-30-20-10, FCOM-DSC-30-30-10)
a. Wing – valves CLOSE
b. Engine – valves OPEN
On the ground, with the PROBE/WINDOW HEAT push button in AUTO, when are the probe and mast heaters activated?
