For carrier-based aircraft, the minimum ,valueto be used for A is 4, ,fieprepenting a basic condition associated with catapult launches. For ,attackand fighter aircraft, add pitch, yaw, and roll accelerations aa applicable. For helicopters, forward acceleration is unrelated to acceleration in ‘other directions. Teat levels are based on current and near future helicopter design requirements. . . When,forw~d acceleration is,not know, the high,value of the acceleration range should be used.
A is derived from the thrust curve data for maximum firing temperature- . Where is the maximum maneuver,acceleration. In some cases, the,maximum maneuver acceleration and ,themaximum longitudinal acceleration will.occur at the same time.
