Are you curious about the new glass cockpits available in general aviation aircraft? There have only been a few major changes in general aviation in the last 50 years, and this is one of them. In 2003 both Garmin and Avidyne came on board with their versions of the glass cockpit. Cessna, Cirrus, and many other aircraft now come equipped with the glass cockpit as standard equipment.
The G1000 offers increased safety through multiple backups for critical components, and a standby battery with standby instruments similar to the level of safety the airlines incorporate.
To gain a thorough understaning of the G1000, I highly recommend Max Trescott's "G1000 Glass Cockpit Handbook" on his blog at "Trends Aloft".
