I have held an SIC type for a turbojet for about five months and have not had a chance to use it since it was issued. Without any experience in the aircraft I went back to training to upgrade to PIC.
You’ve given your interview answer here.
This was a judgement call and you shouldn’t have done it. Lacking experience in the actual airplane is what caused you to fail the PIC ride.
You were eager to advance and did not want to turn down the opportunity from an employer you really liked yadayadayada.
Don’t blame the seat support or the Examiner.
Was this a professional seat support as in provided by the Training organization?
