RA and S/O did nothing?
As a lowly rated 90 hour pilot studying for ATPL exams I think it's truly astonishing that the S/O sat there and simply ignored the RA. Comprehensive retraining is required at the least and I would suggest dismissal.
Surely it's simple enough to disengage the AP and respond to the instructions given. Most of the time they are shouted at you! Make manoeuvre, ensure threat is eliminated then get on the blower to atc to let them know what's going on. Final step is to apologise to the now very angry captain who has pissed on his trousers due to the RA and explain what you did and why.
Is that somewhere near correct?
I feel that most of this is being exasperated by MPL schemes and the bank of mum and dad paying for such courses.
