Boeing Studies

After their own in-house study of an OFW transport, the Boeing Company, under contract from NASA, developed an OFW design that would fit current airport designs and mccl current FAA requirements. To satisfy the FAA requirement that the passengers face no more than 18 degrees away from the flight direction on takeoff and landing (or have head restraints), the aircraft was designed to take off without sweep, which required folding wing lips. The landing gear track w as set at 60 feet

The FAA requirement on passenger orientation is. of course, met by. and may agree with, the upper deck seat angles on Boeing 747 aircraft One may argue that if passengers were seated facing rearward in a seat with side head cushions, a much larger angle might be permissi­ble.

Passenger entry and emergency egress, engine and landing gear integration, as well as airport compatibility and terminal utilization were studied (428). Four engines are placed under the passenger compartment. This configuration, because it is designed to take off without sweep, could not become the New Large Aircraft. Nevertheless it could accommodate 440 to 460 passengers and demonstrated an OFW could be designed with existing regulatory con­straints.
