This study evaluates symbols and formats for the F/A-18 Hornet head- up display (HUD) and Attitude Directional Indicator (ADI) for use by pilots in recovering from unusual aircraft attitudes. Two surveys were conducted to collect pilot opinions on various symbols and formats, based on past experimental research and current recommendations. For the HUD symbols according to the amount of information these symbols provide for the pilot while he is in an unusual attitude. In some cases, the pilots also were asked to choose their preferred symbols. The second survey was based on the results of the first and was administered to 56 F/A-18 pilots. These pilots selected their preferred HUD or ADI display formats, choosing one from two to five possibilities in each case. The specific symbols and formats that were evaluated are described in detail. Survey results are provided, and recommendations are made for display implementation and for further research and testing of symbols and formats. Keywords: Jet fighters, Attack bombers, These
