Dick, we had a QFI on 29 who was an ex trapper, and he was somewhat annoyed to be chosen for a check ride when the trappers arrived on a routine visit.
They taxi out in a Mk7 and roll on to the runway without a word having been said since signing the authorisation book, so the trapper in the back said "how about some checks Fred" ?
Fred replied "fuel and noise" and away he went.
They failed him.
