but since about a year ago I bought a little Garmin Aera 500 with a yoke mount,
Ghengis,
If I remember correctly, you busted some class A airspace in the past (I am pretty sure I remember correctly as I was surprised that someone of your calibre made such a simple mistake using DR - but if I am in error please forgive me). Did you buy the GPS as a result of that, and if so, did you start using it for primary nav?
Just curious why people dislike using GPS so much, and I am glad to see you are a convert....not wishing to start a GPS debate though
