Just to clarify for those not in the know, QRA has three states. NORMAL does exactly what it says on the tin. RESTRICTED meant there was an issue that could cause a risk to normal, safe operations. That could be weather, engineering or diversion problems. So being restricted meant that we would only get launched for an actual intruder - no practice scrambles or the like. MANDATORY meant that something was badly wrong - again, weather or a serious engineering issue - and it was acknowledged that launching QRA may mean the loss of the aircraft or crew.
Oh, and BEags, we especially loved the spoof position checks. How we used to laugh when we were out of range of any ground station or nav aids and realised that we had just fixed the kit with the wrong present position. Ah, those chaps in their cozy tanker. We loved it!
