CRM is a nice idea.
However in the reality of life, CRM only works if both pilots are open to participate.
Many senior pilots consider the FO redundant and this attitude blocks their acceptance of opinions and suggestions.
EG. One suggestion I made to a senior captain (15yrs+) regarding a decision to divert while offshore to collect pax (who had been bypassed by another aircraft due their fuel limitations),was made 3 times using all the lovey dovey CRM insistance that I could muster. Short of taking the controls I had made my objections clear.
We had IFR conditions onshore and fog offshore and my fuel usage calculations delivered us onshore (assuming VFR) with below minimum reserve if we did the diversion. We collected the pax and then proceeded inshore to find the field socked in and the ILS U/S (Not that we had the fuel to perform the proceedure)
A decent was initiated through cloud into the fog and we emerged 200agl, 1 mile from a 300ft mast. Both low fuel lights were on and when we refueled I noted we had total 180lb remaining. Not a lot for the S76.
It was a pathetic display of leadership and management and had the makings of a great CRM course example for poor command decisions.
