Expanded Abnormal; Altitude Miscompare; Airspeed Miscompare; Dual Gps Failure - Cessna Grand Caravan 208B G1000 Manual

SECTION 3 CESSNA
ABNORMAL PROCEDURES MODEL 208B G1000

EXPANDED ABNORMAL

ELEVATOR MISTRIM
Indicates a mistrim of the elevator while the autopilot is engaged. The
autopilot will normally trim automatically as required. However, during
rapid acceleration, deceleration, or configuration changes, momentary
illumination of this message may occur accompanied by minor
fluctuations in the flight path. If the autopilot is disconnected while this
message is displayed, high elevator control forces are possible. In the
event of a sustained illumination, the following procedure should be
followed:

ALTITUDE MISCOMPARE

This message is displayed when the G1000 detects a difference of 200
feet or greater between the pilot's and copilot's altitude information
(displayed in the upper right of the PFD). Refer to GARMIN G1000
Cockpit Reference Guide for additional information.

AIRSPEED MISCOMPARE

This message is displayed when the G1000 detects a difference of 7
KIAS or greater between the pilot's and copilot's airspeed information
(10 KIAS difference during takeoff or landing roll). Refer to GARMIN
G1000 Cockpit Reference Guide for additional information.

DUAL GPS FAILURE

When both GPS receivers are inoperative, the G1000 system will enter
one of two modes: Dead Reckoning mode (DR) or Loss Of Integrity
mode (LOI). The mode is indicated on the HSI by an amber "DR" or
"LOI". Which mode is active depends on the distance from the
destination airport in the active flight plan.

TRANSPONDER FAILURE

Transponder failure may be indicated by a red "X" across the
transponder display or failure of the transponder to accept codes or
mode changes from the PFD.
