Strafer, I'll have you know that not all RAC members are old duffers! Some are even under the age of 30 do you know..... They even allow sprog's in now for "family" days.
Anyway back to GPS.... Surely it is not beyond the realms of possibility that a totally integrated planning/mapping system that can be downloaded directly to a GPS can be developed?
The ability to plan a route and get all current NOTAMS, Wx, airspace as well as topographical data in one place and then shove it into one box in the cockpit (via USB "dongle" or whatever) would make life an awful lot simpler and less prone to mistakes.
I suppose it just requires all the different agencies to get together and communicate.
