Abstract

Flying qualities and performance flight testing of the Navy A-7E airplane for the carrier based, sea strike mission were conducted during a 3.0 hour flight simulation phase, a 20 minute taxi test, and four test flights for a total of 5.7 flight hours. Test loading consisted of full internal fuel and wing pylons on stations 1,2,3,6,7 and 8, for a maximum takeoff gross weight of 31,155 pounds. Deficiencies identified during flight testing of the 1960's vintage airplane were evaluated to determine what specific improvements would be required to meet current and projected operational requirements.

The delayed engine response during waveoff will result in fouled deck landings and ramp strikes and is a Part I deficiency which should be corrected prior to further testing. The low specific excess power, low sustained load factor, and low instantaneous turn performance severly limit the capabilty for effective air combat maneuvering increasing the vulnerability to hostile fire and are also Part I deficiencies which should be corrected prior to further testing. A total of seven Part I, seven Part II and two Part III deficiencies were discovered relating to the flying qualities and performance of the current A-7E.

Within the scope of this evaluation, the A-7E airplane demonstrated limited potential for the sea strike mission. The A-7E will be satisfactory upon correction of the Part I deficiencies.
