Sorry to mention it as we are all L1011 lovers, but some of our fleet of L1011 had at one time (until they visited the vet) an interesting crew awareness extra.
The number two engine would run down when the Fe pressed to transmit on his HF box two.
One day seeing the engine running down the unbriefed captain applied a fistfull of throttle and yelled (communicated) to the FE, who... let go of his press to transmit switch and the engine was over boosted.... Just like that, all at fl.350!
Aircraft landed Istanbul, number two took a week to be changed.
Commander heavily ticked off for not proceeding to destination on two engines, as his holiday with 200 plus passengers cost a bit.
Haveing pointed out the serious predicament if finding himself on one engine later, he was told this had never happened and was therefore unlikly to have been a problem.
He resigned and was upset by this incident.
Sometime later as a result of this lot, another captain spent 5 hours on two engines London Bahrain in a L1011, now this time some management were pro this, other management were horrified.
It was quite a challenge pleasing everyone in our company!
