Anti-Ice Leak Detection Controller: maintains leading edge temperatures, controls bleed air leak detection system, auto closes valves to mx temperature
2 channels, dual channels
What does a WING OVHT msg indicate?
Bleed overheating the wing, auto closes both wing anti-ice valves
What does the ICE DET TEST complete? What must be on to accomplish the test correctly?
Tests both ICE detection and air data sensor heaters
AC power MUST BE ON
Which leading edge/slat are heated? What happens when the slats are extended?
the inboard slats
Extended= heated even more to compensate
What indications are changed when the WING and or COWL A/ICE is ON?
White arcs on the N2 appear: 0-77% N2 ( just for wings)

How is the XBLEED switch operated? What position does it fail?
Last selected position

It has an independent pressure transducer in a double walled duct
Not a PRSOV
No blow out plunger
What is the windshield wiper speed limitation?
How is the speed of the wipers determined? CA or FO? Is there a delay?
Speed of both wipers is determined by the last selection, either side
5 second delay
What is the pre-takeoff contamination check? When is it conducted? Why?
Ensure critical surfaces are free of frozen contaminates prior to T/O, use flashlight or visuals to inspect the upper surfaces of FCs, may need to get pax to move to see wing
5 min before takeoff - if exceeded can repeat
HOT was exceeded or not valid due to WX change
Does + SN have a HOT? Can you T/O with +SN?
YES, in 7/9 w/ pre-contamination check completed

What bleed air is used in the 7/9?
