That would be Idris.
I've also taken part in A&AEE trials in Karup in Denmark, Yuma and El Centro in Arizona and Brunei. Never having been on Rotary icing work I've missed out on the long trips to Canada and Norway. As for ranges in the UK I've also used Studland Bay and Porthkerris on the Lizard.
Also there were trials in Ottawa with the icing rig there.I also seem to remember as well trials over Greenland with XS235 comet.
The Cobham one was off Fairmile; I saw a map of Cobham once with 'RAE' in
small letters at the north east end of this road. (Something to do with 'Cobham
Armour'?). I'm also remembering a MOD(PE) place at West Byfleet but I'm not sure
if this was RAE; could have been something to do with MVEE (Military Vehicles
Evaluation Establishment) at Longcross.
MVEE is basically next(attached) to EQD and Im sure RAE members would of been there calibrating or testing aeronautical equipment to distrcution.
Also back to Cobham it might of been Wisely airfeild (after a little searching) as according to the net it was used for testing vickers aircraft and did have VOR and DME .
