Simplicity Is Stressed in F-15 Operations, Maintenance

Edwards AFB, Calif.—Simplicity in operations and maintenance is proving to be a built-in characteristic of the McDonnell Douglas F-15, according to USAF officials in the aircraft’s flight test program here. The new Air Force fighter, which will become fully operational in 1976, was designed from the outset to provide its oneman crew with a simplified, highly automatic air-to-air and air-to-ground weapons delivery system.

Aircraft Fuel-saving Measures Debated

Reston, Va.—Vertical, cambered winglets, developed at National Aeronautics and Space Administration’s Langley Research Center as vortex spoilers, show promise as a simple, near-term approach to saving significant amounts of aircraft fuel by reducing induced drag.
