PS: Why did the seatwarmers in Canberra ever agree to Australia giving away A----- for Y??? We don't live in Yustralia?? North America would never give away N, likewise Great Britain G, France F, Germany D, Italy I, Canada C??
A bit confused there old boy! The aerodrome location indicator prefix changed from A to Y in the early 90's. Fort Fumble had a reason for it, but it was full of hot air as usual (have a look in the AOPA magazine in the early 1990's for the story). The N, G, F, D etc aircraft registration prefix is totally different. Australia started at G-AUxx and when it changed to VH-xxx the aircraft that were already on the register then became VH-Uxx hence a lot of old aircraft carried a reg starting with U. Do a Google for the full story.
