Boys and Gurlz
It doesnt matter how many movies of CAS busts you put up on some website. I've been to two ATC units recently and it's very interesting stuff, especially the radar track videos, but it won't make anybody (including myself) fly any differently.
The only way is forward, and the only way forward is to improve navigation. And the only way to do that, in the context of a "45 hour PPL" (which the flight training industry will fight till death - overtly and covertly - to keep unchanged) is a complete revamp.
Ditch the stupid and ridiculous 19th century slide rule (which Babbage would have immediately understood) and the many hours spent (wasted) learning how to use that piece of crap (without, in nearly all cases, actually ever acquiring an understanding of how it works) and instead spend those hours using electronic aids, and a GPS.
This whole business is so old fashioned it's going to get swallowed up in its own Olde English backside if it carries on for much longer.
Today I flew from Corfu LGKR to Padova LIPU. Guess how many planes I saw or heard en route (distance about 600nm). Answer: 0 and about 3. That is what is in store for UK GA unless something is done.
It's even worse down in Greece.
