...lost it??
tp67,
No, it's not that the Captain has 'lost it' but rather dealing with a malcontent crew member who refuses to follow the plot.
Every airline has 'em, and many reside in the RH seat, feeling that they have somehow been maligned by the system, and many times strike back with sarcastic comments to other crew members (including the Commander) as wll as ground crew.
A couple of airlines that I worked for had First Officer assessment forms that were requested to be filled out each month by the concerned Captain...the two being scheduled together for a 28-30 day period.
I showed this form one time to a 'wiseguy' co-pilot, who oddly enough was in line for an upgrade to Command...and it turned his thinking around 180 degrees.
Mister nice guy, personified, he became...and went on to be a rather well thought of Captain.
IE: some guys need a wake up call, no matter how much it hurts.
