Do you realise the importance of communication?
A factor that is instrumental in determining interpersonal behaviour on the Flight Deck is the “Role” of a pilot. The problem is, when the other pilot is not handling things the way they should, ideally you’d like to take control away from him but since doing so may be perceived as a lack of faith in the other’s ability, you don’t. This is where MCC plays a vital part in avoiding catastrophe.
Although there are a lot of other factors contributing to safety, I reckon good communication is the best method to avoid most mistakes.
For e.g:
A twin prop commuter aircraft was commanded by a pilot who was also a senior manager in the airline and known to be somewhat irascible. The F/O was junior in the company and still in his probation period. It was at the end of an already long day, and the captain was plainly annoyed when company Ops asked for a further flight, but he reluctantly undertook it. During the approach at the end of his leg, the First Officer went through the approach checks but received no response at all from the captain. Rather than question or challenge the Captain, the First officer sat tight and let the captain get on with it.
The aircraft flew into the ground short of the runway because the First officer did nothing to intervene. It transpired that the captain had failed to respond to the checks not because he was in a bad mood but because he had died during the approach.
