CAA Flight Test
The CAA has done a sterling job of retaining a credible flight test team in recent years. Until last week it had 3 - 4 Flight Test Engineers including a FW Performance and handling qualities specialist, an Avionics expert and a very experienced Rotary Wing FTE graduate of ETPS. Its 2 ETPS trained test pilots covered every thing from single seat autogyros to A380s ...and did it safely and professionally as hopefully anyone who has flown with them will testify.
Since EASA came into being some 10 yrs ago the CAA has supported the aims of the agency. Four CAA FTEs started up EASA's Flight Test Department and all of the CAA flight test team have continued to certify and validate mainstream aircraft under contract to EASA; sometimes in multinational teams.
Additionally the CAA has retained the necessary capability for national certification of Annex II (non EASA) aircraft including the Police aircraft, non standard experimental aircraft (Met Flight etc) + Section S Microlights and Section T gyros.
The CAA has restructured SRG and merged it with Airspace to become SARG.
Genghis has it about right, but contact the CAA for more info.
