OK. What happens when a "student" has a question on how/which way the flows/call outs are supposed to be done properly? ie who says what first, who responds, etc...
The instructor should help in that aspect also.
This is one of my peeves with contracting out the training (per se).
My previous company would contract out Flight Safety in LGA for us. Then I would get the call to go down and "help" out students to get the procedures,flows,callout in the proper sequence. Because they are having trouble, failed due to a checkairman not satisfied by the way things "flowed", the FS instructors would add a little CommutAir stuff in to the procedures...

AND:
Another reason was that it was taking money from me, and the POI from the FAA (if it is still the same one) is a SCAB!!! (on the list).
OK, enough venting.

The other side of the coin, we have our own instructors, and things are still being taught a little different. Different opinions/techniques. BUT, they have meetings to pound these issues out.
