Q

What actions occur in flight when the WINGSTAB switch is moved to the on position

A

1) Air Management System Controller commands the Wing Stabilizer Anti-Ice valves to regulate system pressure, provided the temp and altitude are within the operational envelope

2) FADEC reschedules engine N1 idle setting to maintain sufficient pneumatic supply.

3)Avionics System reschedules stall warning and airspeed protection.

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.
