Just spotted this on the Flyer forum
FLYER Forums • View topic - Airfields with wi-fi access
Surely any airfield worth it's salt would at least have a phone line, and surely they have a broadband connection. All they need to do is allow those pesky pilots access to the signal.
As the technology ramps up and gets cleverer (NATS satnav) then you will surely be looking at much heavier penalties for airspace infringements, and probably rightly. If GA embraces the technology, then it may even be possible to limit the growth of controlled airspace (Norwich?).
I have just started using Skydemon and am running it on an Archos 9 tablet with a bluetooth GPS. Fantastic! Do your preflight planning on it as a regular PC and then one click starts the GPS and it transforms into a moving chart.
