G100 was a good bit of gear; used one to track across Oz on a couple of trips; BUT they are old and NOT IFR approved. The batteries are no longer available and once that goes, that is it. If you have one, bung it on ebay and it will be snapped up, for parts.
Didn't a Metro freighter smack into a hill near Tamworth a few years back, using one for a DGA in IMC?
In the same boat are the Trimbles; while they ARE TSO'ed for RNAV (depending on the model and installation), they will not be supported for data by Jepps after the end of 2008; so will no longer be IFR usable - although I'm sure there will be plenty still being used IFR anyway
. "Welcome to the World of Modern Navigation" - read that intro every day on a TNL in a B200, just after the computer check which reads 1994......
