Cabin Pressure Controller Inputs
 

Hello Everyone,

The air data inertial reference units (ADIRUs) provides ambient static pressure, baro corrected altitude, non corrected altitude and calibrated airspeed to both automatic controllers. The ADIRUs receive barometric corrections from the Captain's and First Officer's BARO reference selectors.

The automatic controllers also receive throttle position from both stall management computers and signals from the air/ground sensors.

Why does it need both corrected and non corrected altitude?
Why thrust lever position from the Stall Management Computers ?
