Chaps - can anyone recommend a good WWW site that explains more of how GPS systems work for aviation?
I'm wanting to buy one (love gadgets), but I'm not sure whether to go for an EnglishAl kind of setup (prob an iPaq plus some sort of receiver) or to go for the all in one incl. database kind of thing (Skymap, Pilot III etc.)
For what it's worth on the "why not buy a cheaper civvie GPS unit" question, I have a Garmin GPS II (use it on the m/bike and have all local GATSOs prog'd in as waypoints) this unit actually shuts off at 103mph. Thi is going to make it useless even in a C152! (and on a Fireblade

)
Cheers
