Niggilb....and I suppose TCAS is fitted as well!!!!!! most of the sevice fleet did not comply with TCAS when I was flying the routes!!!!!And what else do not only the Nimrod have not fitted but the rest of the Multi engine fleet. This is not a new problem and is one that will be completed only when aircraft are re routed many times and end up unable to complete tasks. Boy am I glad to be out of it now.
