I bought one of the McMurdo units last year with a healthy discount at Aeroexpo expecting it to comply with KK(1), but I'm still not sure if it complies.
According to the man from the CAA that I spoke to yesterday there are no personal ELT's that conform to the CAA/EASA specification.
Anyway, I did the Normandy/ Channel Islands route last week. They don't seem to have changed the bottom of the flight plan form (does this qualify as UHF emergency radio?)
I flew back from Deauville last week and filed my flightplan via OLIVIA and that now comes with the ELT box pre-checked.
I agree entirely with bose-x. On a sunny summers day you are going to end up with large amounts of aircraft all trying to cross the Channel Dover to Calais causing potential conflicts.
