Section 4 – Normal Procedures
GFC 600 Power Up
During power-up of the GFC 600 system, an initialization splash screen displays on the GMC 605 Mode
Selection Panel. The splash screen displays the following information:
• GFC 600 title
• Electronic Stability and Protection (ESP)
• Software version number
When this information has been reviewed, the pilot is prompted to continue (CONT) by pressing the HDG
key and the GFC 600 enters preflight test.
During the preflight test the GMC 605 will display PFT in the Message Window. LED fault lights on the
GMC 605 autopilot mode panel cycle through a test sequence, three amber lights followed by three red
lights, then extinguish if the preflight test successfully passes. The autopilot disconnect tone sounds at
the completion of the preflight test. If the GFC 600 passes preflight test, the display on the GMC 605 will
be blank and all LED fault lights extinguished.
If the GI 285 remote autopilot mode display is installed, it will cycle through an annunciator light test during
the GFC 600 preflight test. All lateral mode annunciations will illuminate amber, followed by AP, YD, TRIM
annunciations in amber, all vertical mode annunciations illuminated amber, and finally the AP, YD, and
TRIM annunciations in red. If the preflight test passes, all annunciations on the GI 285 will extinguish.
Flight Director / Autopilot Normal Operating Procedures
Autopilot/Flight Director mode annunciations on the GMC 605 displayed in bold fonts indicate active
autopilot/flight director modes. Armed modes are indicated in smaller fonts. Normal mode transitions will
flash inverse video for 10 seconds before becoming steady. Abnormal mode transitions will flash for 10
seconds before the default mode is annunciated as the active mode. Default autopilot/flight director modes
are Roll (ROL) and Pitch (PIT) modes.
If installed, active modes are indicated on the GI 285 Annunciator Panel in green, and armed modes in
white. Abnormal mode transitions will flash amber for 10 seconds before the default mode is annunciated
as the active mode in green.
The GMC 605 display panel is divided into three sections. From left to right the sections are, lateral
autopilot modes, vertical autopilot modes, and the message window.
