What you are saying is that an employee is not allowed access to the FD, even though they are an 'authorised person'. I was with some airlines that did not allow FD visits, but if an employee was ticketed they could occupy an FD jump seat with capt's discretion. That same employee would not be allowed to visit during the flight????? The ops manual even seemed to say that a pax friend of an employee, travelling on a staff ticket on a full a/c, could occupy an FD jump-seat even though they were not flight safety trained. How daft is all this?
