I'm in a club with a Cherokee 140 now - flown it a bit, filing IFR in VMC to get acquainted with ATC and local area here. . .I got recurrent in a Cirrus w/Avidyne, then time in a steam 172 with 430 and 530, and the 140 with Aspen EFD - and the sort of "cartoon" like Garmin 355 . . . Gonna take a safety pilot and do some approaches Thursday. Spent today using the Garmin simulator, watching Aspen YT videos, and RTFMs. . .thing is, I'm not seeing there is a big difference - glass is basically pictures of steam gauges; handy, but kinda "busy" displays. GPS boxes are all much alike, as are the EFDs. I'm not complacent - I hope. I know the bold face and systems, V speeds, etc. Just feel like I'm not thinking of something. . .
