ARMY AIRCRAFT VOICE-WARNING SYSTEM STUDY
Abstract
The report describes an analytical study that was intended to serve as a basis for the application of voice-warning systems (VWS) for the UH-1B and UH-1D (Huey), AH-1G (Cobra), CH-47 (Chinook), CH-54 (Skycrane), and OV-1 (Mohawk). The following problems of installing a VWS in these Army aircraft were studied: (1) the identification and selection of messages for maximum effectiveness; (2) the determination of priority sequences; and (3) the integration of the VWS into existing cockpits. The study involved the collection of basic data and the conduct and validation of mission analyses, operational sequence diagrams, task analyses, aircraft configuration analyses, pilot opinion surveys, and Army aircraft accident analyses. In the report, priority sequences are derived for all major emergencies for the six vehicles; further analytical effort is described which reduced the list to 20 messages for inclusion in the VWS. For each aircraft, 2 lists of 20 messages are proposed; one list assumes additional sensors, while the second assumes the current sensor system. Recommendations are made for message structure and content, priority sequences, integration of the VWS with the current visual-warning system, general sensor requirements, interlocking between VWS messages, and other related considerations.
