I have sat all my ground exams in the last 9 months ( and passed!) using no devilish electronic devices as I was told that I could not use any form of electronic calculator at all for my exams.
When I did my QXC etc I asked the CFI ,tongue in cheek, if I could use any of the electronics as the aircraft had all the usual stuff plus GPS.
He told me that the equipment was in the aircraft and who would know?
Any way I didn't use any of it but did ask for QDM's at both airports,so whats the difference?
