Abstract : An evaluation of the F-14A departure/flat spin environment, as simulated by the Dynamic Flight simulator (DFS), was conducted to determine the capability of F-14 pilots to complete NATOPS spin recovery procedures. The evaluation was performed in both fixed and moving base (dynamic) modes using standard qualitative and quantitative flight test techniques. Nineteen F-14A U.S. Navy fleet aviators participated in this study and experienced departures and fully-front; -Gx). The objectives of the experiment were to (1) Determine the effects of Roll Stability Augmentation System (Roll SAS) ON/OFF, aircraft loading, and asymmetric thrust on the severity of simulated F-14A aircraft departure/spin entry; and (2) Determine the effect of increased throttle friction, Roll SAS, harness lock, and -Gx on the pilot's capability to recover the simulated F-14A aircraft from a departure/flat spin. The time/altitude loss data, and pilot questionnaire data, indicate that the optimal recovery aid is the locking of the harness, with Roll SAS activation and throttle friction remaining as secondary recovery aids. In addition, the most severe spin and departure entries occurred under asymmetric thrust conditions. Entries with aircraft loading and/or the Roll SAS activated followed asymmetric thrust closely in contributing to entry severity.
