Agree with PP Radar - which military radar? do you mean Aldergrove Approach? If so, this is most certainly civilian.
Fitter, please explain your comment about
military fast jets (unequipped with compatible transponders)
The mil either have Mode C (which
is to be switched on at al times) or Mode s on later models. Both versions will happily satisfy the plethora of devices we can fit to our aircraft. Furthermore, mil regulations
require them to talk to an ATC or ASACS agency if they enter IMC; something not required for civil aircraft.
