5 - ICE DETECTION TEST KNOB
Permits the half-wing, horizontal stabilizer and engine air inlet anti-icing
subsystems to operate for test purposes, by simulating an icing
condition on ice detectors 1 and 2. The adequate system operation is
confirmed by the illumination of the OPEN inscriptions in the anti-icing
buttons, which indicate the current valve position.
NOTE: The ICE CONDITION, ICE DET 1 (2) FAIL and BLD 1 (2) LOW
TEMP messages are displayed during test. The CROSS BLD
OPEN message is also presented for airplanes Pre-Mod. SB
