Every one has two tries on upgrade with an 18 month cooldown period in between, if both are flunked he will continue on as FO for the rest of his life in the company.
Did this actually happen?did the FO stay within the Airline?
Obviously the Fo was put forward to be checked and as such should be quite prepared to pass,it must be quite hard on the check airman to fail such a person knowing that the consequence would be a failed professional life..I would not like to be in the Check airman shoes one bit.
