Q

How is pressure regulated within the Wing Stabilizer Anti-Ice system with the WINGSTAB switch in the ON position?

A

The Air Management System Controller (AMSC) senses temperature and pressure of the pneumatic supply and pressure downstream of the Wing Stabilizer Anti-Ice valve, then modulates the Anti-Ice valve position to maintain system pressure within limits.

Q

What actions occur when the ENG1 or ENG2 switch is moved to the ON position?

A

-Air Management System Controller commands the respective Engine Anti-Ice valve open.

-Respective TT0 electric probe heat is turned on regardless of temperature, weight on wheels, or engine status.
