Garmin G600 manual System Power Up

1.2System Power Up

NOTE: See the Aircraft Flight Manual (AFM) for specific procedures concerning avionics power application and emergency power supply operation.

NOTE: Refer to Section 6 for system-specific annunciations and alerts.

The G600 System is integrated with the aircraft electrical system and receives power directly from electrical busses. The GDU 620 and supporting sub-systems include both power-on and continuous built-in test features that exercise the processor, memory, external inputs, and outputs to ensure safe operation.

During system initialization, test annunciations are displayed. All system annunciations should disappear typically within the first 30 seconds after power- up. Upon power-up, bezel key backlights also become momentarily illuminated on the GDU 620 display bezel.

On the PFD, the AHRS begins to initialize and “AHRS ALIGN: Keep Wings Level” is displayed. The AHRS should display valid attitude and heading fields typically within the first minute after power-up. The AHRS can align itself both while taxiing and during level flight.

NOTE: Fastest AHRS alignment is achieved with the aircraft stationary and with all AHRS inputs valid (3-D GPS position, magnetometer, and air data). During initial power up on the ground, no GPS position and/or magnetic anomalies are common. If the aircraft is taxied prior to AHRS alignment, alignment may be delayed until after a valid 3-D GPS position is available.

NOTE: During in-flight alignment of the AHRS, minimize aircraft maneuvering. The AHRS will align with shallow banking and pitch angles (less than 20 degrees of roll or 5 degrees of pitch). AHRS alignment may not be possible during more aggressive maneuvers.
