So what responsibilties does an in instructor have, even on a "lapsed ticket?"
I know at the end of the day P1 has the final decision, but as part of the crew at which point can/should you say enough is enough and take control.
I'd do it as soon as I felt that the actions of P1 weren't safe.
I know it was only a PPL flight, but it di have more than a one pilot crew.
Was there any CRM/MCC?
The last thing I want to do is bring up a whole new argument, but IMHO CRM was seriously lacking here.
Opinions?
