I won't go into any specifics, but for the 737, the planes roll out of the factory and are towed over to Renton Field (RNT
) The Renton plant is on the other side of the river from RNT
, so it's a short tow. There they do engine runs and prepare the plane for B1 (first Boeing flight. Pilot, Co-pilot on board. no one else). When the functional tests are complete and everything checks, the plane is flown on its B1. This flight usually lasts about 2.5 hours and goes through numerous standard tests. The plane always lands at Boeing Field International (BFI
) at the end of B1. At BFI
any annomolies and flight squawks are worked out. More engine runs, as required. Then the B2
flight is flown. If there are no more flight squawks or any other issues, the C1 (First customer flight) flight is next. If that has no problems, delivery is next. If it does have issues, B3
and so on can be flown, if necessary, until no problems exist. After all is taken care of, DELIVERY!!! Delivery flights with a very, very, rare few are flown by the airline pilots.
