Abstract
Flight tests where conducted at Cambridge-Dorchester Airport (KCGE) and Easton Municipal Airport / Newnam Field (KESN) in a Cessna 402B aircraft using a head-up display (HUD) and a Kollsman Enhanced Vision System (EVS-I) infrared camera. These tests were sponsored by the MITRE Corporation's Center for Advanced Aviation System Development (CAASD) and the Federal Aviation Administration. Imagery of the EVS-I infrared camera, HUD guidance cues, and out-the-window video were each separately recorded at an engineering workstation for each approach, roll-out, and taxi operation. The EVS-I imagery was displayed on the HUD with guidance cues generated by the mission computer. Also separately recorded was the inertial flight path data. Enhanced Flight Vision System (EFVS) approaches were conducted from the final approach fix to runway flare, touchdown, roll-out and taxi using the HUD and EVS-I sensor as the only visual reference. Flight conditions included two-pilot crew, day, night, non-precision course offset approaches, ILS approach, crosswind approaches, and missed approaches. Results confirmed the feasibility for safe conduct of down-to-the-runway precision approaches in low visibility to runways with and without precision approach systems, when consideration is given to proper aircraft instrumentation, pilot training, and acceptable procedures. Operational benefits include improved runway occupancy rates, and reduced delays and diversions.
