Apart from technical issues, let's deal with the psychology and procedures:
- Should the captain have leave his seat to an adolescent yet he had a bad feeling ("Do you "really" have your licence ?"), furthermore in front of his girl friend ?
- Does it exists a procedure that the Capt. didn't followed that would have prevented him from leaving his seat to an adolescent ?
- Does it exists a procedure that could have allowed the PNF to take control by strengh after the PF has re-taken control without annoucement yet the PF had admitted having lost the plane ?
- Is there a procedure that would have allowed the Captain, when entering the cockpit, to understand that the problem was dealing with the PF mental attitude ?
- Is there a procedure that would have imposed him to discharged the PF and take control or give control to the PF ?
Thank you
