I flew a mission into South America with one of our "less than stellar" Navigators. At the first "In Country" stop a senior Navigator Flight Examiner from Air Mobility Command got on board for a "no notice" observation flight on our Nav. The rules of that program stated that they were to be "informational only" and the person/crew observed did not receive a grade and could not be "busted" unless an unsafe condition resulted. The crew worked well together and we thought we were pretty cagey covering for our weak sister.
After the mission, I received an "informal debrief" on my navigator's performance. It came as no surprise when the evaluator summed up the nav's contribution to the crew.
"You would have been better off with an empty chair."
