King Air C90GTi, Pilot Training Manual

FOR TRAINING PURPOSES ONLY
16-24
When selecting reversionary modes, all flight
director and autopilot functions should re-
main normal and unaffected.
ADC Reversion
The Air Data Computer (ADC) switch on the
reversionary control panel provides reversion
capabilities for the ADCs. If a single ADC
fails, the red IAS, ALT, and VS failure flags
will appear on the affected PFD and a white
xADC flag will appear on the cross-side PFD
(Figure 16-48). The ADC switch should be
moved to the operating ADC (e.g., if ADC1 is
still working, choose ADC1).
Miscompare indications also require the use of
ADC reversion. This occurs when the pilot
and copilot systems are still functional but
have different values displayed on the PFD’s.
