The airport directory database contains information on landing facilities, such as
operating hours, services available, and transportation/lodging resources.
Airport directory information may be available from multiple sources and
coverage areas. This database is updated on a 56-day cycle.
7.2 Electric Standby Attitude Gyro
If an electric standby attitude gyro is installed, the gyro operates from the aircraft
electrical system with a dedicated emergency battery specific to the electric gyro.
The electric attitude gyro battery capacity may vary considerably depending on
temperature, charge status, and battery life condition. Low temperatures below
32°F will temporarily degrade battery capacity. Internal chemistry will slowly
degrade battery capacity over several years of operation even when correctly
maintained. A poorly maintained battery will suffer accelerated degradation.
Extended storage in a discharged state and over-charging will permanently
damage the battery. Complete charging is required to bring the battery up to full
capacity if it has been unused for more than four months or partially discharged.
7.3 Autopilot Interface
The G500/G600 acts as a navigation source switching hub to an interfaced
autopilot when multiple navigation sources are available. The autopilot will only
couple to the heading, navigation, altitude, and vertical speed selections on PFD
1. Some autopilots may have navigation source selection integral to their system;
this feature is overridden by the G500/G600 navigation source selection
described herein. Changing the navigation sources displayed on the HSI (by
pressing the CDI button or the 1-2 button) may result in some autopilots
disconnecting or entering a wings level mode.
