Chilli Monster,
Hope this isn't taking us too far off topic - but I wasn't aware that ATC dealt with retractable aircraft any differently to fixed gear.
My Europa is retractable. Other Europas aren't. Whatever the gear configuration, the ICAO code is the same - EUPA. When I give my type to ATC, I always say "Europa". It would never occur to me to say "Europa monowheel", nor, I suspect, would most controllers realise that because I have a monowheel, it's retractable. Is this an issue? I hadn't thought of it as an issue before.
(Interestingly, I think it was at Duxford but I'm not sure, I once had a controller - or it must have been an AFISO if it was Duxford - ask me to confirm that my gear was down. I checked, and it was... and I realised that the unusual gear arrangement would probably confuse anyone who was looking at the aircraft and didn't know what they were looking for - they would probably not see enough wheels, and even if they knew how many wheels to look for, the top of the main wheel remains inside the wheel well when the gear is extended, so it probably looks like it's up when it's not if you're not close to it.)
