737 pilot undergoing command training during line flying. -
The Boeing 737 FCTM makes it clear that the captain not only makes the decision to reject the take off but carries out the procedure as well.
While that applies to the normal crew complement of captain and first officer, it would be informative to know various airline policy when the check captain is operating from the RH seat and training a new captain who occupies the left seat. This assumes the new captain has completed all the required simulator training in the left seat and is now undergoing command line training in the air on revenue flights.
While the pilot in command (in this case the check captain) makes the decision to reject a take off the situation is less clear when someone is undergoing command training on line in the left seat.
Who then becomes responsible for handling the rejected take off procedure? The pilot under training for command? Or the authorised check captain occupying the RH seat? What are the legal issues, if any? All this assumes the pilot under training for his command in the left seat is certified as having a command endorsement on the type gained in the appropriate credited full flight simulator before commencing line training.
