The reason people stopped reporting the RIMCAS faults was because when we did we were told either its being worked on/its the new airbuses they dont have the right transponders/its virgin's equipment that is at fault.
When you are constantly reporting something and nothing gets done to fix it people tend to just say sod it and put up with it. Thats part of the problem with UK ATC, we just get on with it despite sub standard equipment, lack of staff, low morale. Our own worst enemies yes, but experience has taught us that in the end no-one really listens in NATS. And if they are listening the tend to tell you off for speaking out.
