ANALYSIS OF E-2C LONG DURATION MISSIONS

CHI Systems Inc, proposes to study the E-2C mission and to determine the conditions under which its traditional 4-5 hour duration can be extended without additional detrimental effects on aircrew performance. In Phase I we will (1) identify and assess key factors in E-2C fatigue via knowledge acquisition from current aircraft domain experts using interview, survey, and literature search, (2) make preliminary assessment of methods to reduce the aircrew fatigue effects, (3) assess the feasibility of adapting the existing PERFECT (PERFormance Effectiveness of Combat Troops) model for simulating aircrew effectiveness, (4) document the analysis of key aircrew fatigue factors, design information on the PERFECT model, a preliminary assessment of extended duration mission achievement, and a Phase II plan. In Phase II, we will (1) establish the endurance limit conditions under which Hawkeye aircrews can maintain effectiveness, (2) select and validate fatigue factor effects, procedures, (3) use the adapted PERFECT model to assess candidate procedures and technologies for reducing fatigue effects on long-duration E-2C missions.
