I do like the PFD on the G1000 the synthetic vision is awesome. However that doesn't out weigh the short comings of the "FMS".


Things the G1000 can't do:

• Draw a hold. You can only hold at an IAF or missed approach holding point.
• No predictive fuel planning: It will take your instantaneous fuel flow and ground speed to calculate your landing fuel, however during a power idle descent you can fly to the moon, and during climb you'll crash in about 45 minutes. So if you are holding (using heading bug on the outbound and NAV on the in unbound leg. Don't forget your wind correction, especially fun in a 125kt crosswind) on the way to LGA and get a reroute that adds 200nm to your route the only want to figure out if you are going to make it is it do math by hand. Unless you want to dump your entire flight plan.
• No "Fix" page functions like on a Collins FMS. (You don't realize how useful they are until you don't have them)
• VNAV doesn't understand "or above" and "or below" on arrivals.
• No DME holding function
• No route overlay on radar
• No way to generate FMS glideslope to a runway w/o an IAP

The list goes on but those are the ones on the top of my head.


To be clear I'm not saying you can't fly a jet without these features. I'd be more than happy to fly a DC9 w/ DAL. What I am saying is an advance avionics system that is very new should have these functions.

The G1000 was designed for piston singles it doesn't have the brains to be in a jet. But it looks pretty so people buy it.

If you have any other questions let me know.
