− CPCS - Both ADCs provide pressure altitude, barometric
correction, and altitude rate of change data for the
pressurization Digital Controller.
− ICE PROTECTION - Both ADCs provide altitude trip point for the
ice protection system.
− RUDDER SYSTEM - Both ADCs supply the rudder system with
the calibrated airspeed trip point.
− AWU - Both ADCs supply the AWU with the overspeed warning
output.
The ADCs functional test mode is entered when the momentary ADC
Test Switch, located on the Maintenance Panel, is commanded to test,
provided the airplane speed is below 50 kt and the airplane is on the
ground.
The barometric pressure data discrete inputs to the ADCs are set on
the PFD Bezel (barometric pressure selection and correction).
