For the continued development and updating of the operational usage spectrum of Army helicopters, a UH-1H helicopter assigned to nap-of-the-earth NOE training missions at Fort Rucker, Alabama, was instrumented with an oscillograph and a photopanel recording system. Two oscillographs collectively recorded 20 different flight parameters, and a photopanel assembly monitored 9 other flight parameters 14.9 hours of valid data over the NOE course were recorded. For the optimum representation and interpretation of the helicopters performance, the data were processed by the Flight Condition Recognition FCR method. In this program, the FCR technique was used to identify 29 flight conditions including maneuvers and operational categories. These included turns and steady-state flight according to the occurrence and duration of a single flight parameter or combinations of them, each in a specific range. The data presentation includes the operational usage spectrum expressed as the percentage of time in the flight condition categories and various graphic depictions of typical NOE mission profiles.
