A quick check of some stuff that I have shows that use of the airbrake on the Lightning F3 and F6 airbrake was limited to 650/1.3 and on the T5 to 650/1.2. The Meteor T7, F8 and F9 had no limit.
The Meteor T7 Pilot's Notes say:
If the aircraft is yawed at speeds below 170 knots with the airbrakes out, the nose may drop suddenly and the elevators become ineffective until the yaw is removed or the airbrakes retracted The tendency is aggrevated if a ventral tank is fitted. Airbrakes should not be used at airspeeds below 170 knots at circuit height and should be in before the undercarriage is lowered.
There is no such warning in the F8 F9 book.
