Emergency Procedures
3.1.1 Loss of Primary Flight Information
If the primary GI 275 ADI fails (loss of some or all primary flight information,
display is blank, frozen, or unresponsive).
1. Use standby flight instruments for attitude, airspeed, altitude, and
heading reference.
2. If GI 275 reversionary capability is available, the standby GI 275
should automatically change to the ADI page and promptly restore
primary flight information. If manual reversion is required, move the
Reversion Backup Switch to the “ON” position.
3. Refer directly to the navigation source for navigation information (such
as GPS).
4. Seek VFR conditions or land as soon as practical.
If autopilot is engaged:
5. Verify autopilot mode selections and cross check against standby flight
and navigation data. Consider disengaging the autopilot.
