It happens all the time, with everything we do now. However it isn't necessarily the crews fault its the company pushing and pushing them.
I am fed up of having to justify my actions to crews when all im trying to do is set up the safest most expeditious pattern of traffic I can.
yes they have TCAS but they dont see what i see , they dont have the info that I have on what is also planned to happen , so please let me carry on trying to do the best I can.
Ask if you must but if you are refused accept it, we have often already asked for you before you have even come on frequency we think that far ahead.
