Abstract:

During the upgrade of the F-14 to the F-14D, pilots have expressed their concerns regarding the obscuration of the forward field-of-view due to the new Head-up Display HUD supports in conjunction with preexisting windscreen bows. An additional issue involves the proposed use of the HUD as the primary flight reference instrument. The HUD pitch ladder has been criticized for not providing enough information to enhance recovery from unusual attitudes. The purpose of the present study was, therefore, twofold 1 to measure the levels of target detection with and without windscreen bows, and 2 to measure unusual attitude recovery performance using two different HUD pitch ladder formats - Standard versus Enhanced. During simulated flight, twelve subjects were required to make visual detections of enemy aircraft with and without the windscreen bow. Additionally, subjects were required to recover from various pitchroll combinations.
