Remember that you do NOT need to be in sight of the surface to fly VFR!
How do you navigate above 8/8 in VMC outside CAS? DR??
GPS is an excellent navigation aid, yet some view it as a tool of Satan. Incidentally, what qualifies a GPS to be considered 'IFR approved'? The word of Garmin?
Any GPS should certainly be approved for en-route navigation in IMC above safety altitude without the need for other navigation aids. Some of us were taught to fly with only V/UHF DF as the available 'navigation aid' under such circumstances, so having a GPS available in addition should be entirely acceptable. But not, however, for terminal approaches unless a higher degree of performance is included in the GPS.
Devices such as the Garmin aera 500 series will become more and more popular. The CAA is going to have to accept that and MUST change its view on GPS navigation outside controlled airspace......whether VMC or IMC. Yes, much as it will shock certain €uropeans, in the UK we can fly IMC outside controlled airspace if we wish and are suitably qualified.
bose-x, your response to the absurd comments made by LEVC were remarkably restrained, I thought!
