Heaven knows how many passengers would run off the airplane if they knew that their pilot today had never flown the actual airplane they were on. You might be flying with a crew member who either had a thousand landings in the airplane or NONE, ZERO, ZILCH! You have no way of knowing. But fear not, the FAA and the airlines require that the new pilot be accompanied by a designated Line Check pilot, an experienced “old head,” for their early flights on the line.
