G- reg's
I believe that is the maximum number that can be issued (25 x 25 x 25 x 25 = 390,625 - all letters except Q). I was interested in how many are left to be issued.
With micro-lights, balloons, duplicate registrations, aircraft deliveries (not many now - unfortunately) and now gliders, I wonder how many aircraft registrations have actually been used to date.
Anyone work in CAA Registrations Department??
