Don’t confuse good CRM with a p!ssing contest. One of the most irritating F/Os I flew with was so keen to impress me with how far ahead of the aeroplane he was, he would flip over the takeoff card and enter all the landing data before we passed 10000 feet in the climb on a three hour sector. He would be into that FMS to enter a visual circuit before he even knew what approach I intended. During taxy in he would set up the cockpit for the next crew or even the next morning after an overnight. Too bad if the schedule changed!
The old sailing ship masters had it easy. No one else could navigate, so the crew had to toe the line. There was little insubordination or challenging of decisions if the reward was the cat o’ nine tails. Very little mutiny, considering how harsh it was then. Probably because this usually resulted in being keel hauled or strung up from the yardarm.
If only CRM could somehow embrace this ethos....
