Transponder requirements
Hi,
I'm sure its been asked elsewhere, and I did find a CAA leaflet about it, but can someone confirm, what airspace is a 3 axis microlight permitted to fly in, if it has a radio fitted, but no transponder?
When is it permissible by default? When does ATC approval need to be sought? When is it not permitted?
Just interested. I am learning to fly a 3axis, and the airfield I am flying from is sandwiched right between the London TMA, Luton, Stansted and Heathrow!
Thanks a load. IPZ
