2. Checking/Training, whatever. During line training, a student shows clear deficiency on hand flying and they are dangerous. Call it remedial training/failure, doesn't matter. The 1 stripers are always sent back to sim after nearly killing 300 Indians when the TRI takes over the landing.
Not only the 1 stripers... Anyone having 1 or 2 in handling goes back to the SIM. No landing training on a commercial flight.
3. Another student can fly the airplane well, but has trouble with the radio or SOP through unfamiliar environment. Don't anyone dare "FAIL" that poor guy and send him back to the sim. What is he going to learn in the sim? TEACH him, watch for improvement on the return sector. Do they teach TRI's "fundamentals of instruction?" The definition of learning is a change of behavior.
That is what is being done... No one goes back into the SIM for SOP or radio and the like. But if it is the flows, IPT might help. If it is energy management, an additional SIM helps more than a talked down approach.
