What I heard is different. I understand that the check pilot candidates were given a flying exercise that consisted of a none published holding over a fix followed by a full procedure NDB approach manually flown with birds off /FMGCs off /Auto trust off. The company checks airman demonstrated the task himself before the ride and then asked the candidate to do the same.
Almost none were able to complete the task within the reasonable tolerance required by the Flt.Ops. I hear the same exercise is followed on the Sim. Ride with Gulf Air.
