VL - hopefully common sense has prevailed!
With reference to the Fire Service - not only does it create reluctance with aircrew to declare something, but it can make the controller reluctant to make a call out (particularly if you have been berated on the RT by a pilot for their presence).
So a few months ago I had some discussions with them and the local operators to tone down the response, i.e. following the aircraft when not essential. As a result we now have a procedure in place where the vehicles will still turn out to their standby point but unless considered necessary by the Officer in charge, ATC or the pilot, will not follow the aircraft. As this has only been in place since October there probably hasn't been much time to establish the effectiveness but I hope this is a step in the right direction to prevent problems being mis-called.
