When no icing condition has been detected
When will the MP not attempt to control the anti-ice/start bleed valve?
When Ng is 94% or less
In the auto mode, when does the MP automatically activate the anti-ice subsystems?
When FAT is 5 degrees C or less and TRACE or greater is detected
When does the ice detector signal processor perform an internal BIT?

How does the FMC and Air Data Proc. determine the TAS sent to the MP when HADS is operational and airspeed is below 40 knots?
EGI inputs are the primary source
