especially on a/c with an FPA type flight director,
A pox on flight directors of any kind. They not only cause tunnel vision but any instrument flying scan skiils you may have once had, are shot to hell because all the concentration is on a tiny square to keep the needles centred.
Automation dependency includes flight director dependency and has been a factor in numerous IMC approach accidents as well as failure to recover from an unusual attitude. Blind faith in the following of FD needles is a serious issue that needs to be addressed in simulator training. When you have big operators such as those in in the Middle East castigating pilots for a few minutes of manual flying raw data on a sunny day, you have seen FD dependency at its worst. Big brother QAR read-outs gets you every time.
