A Portable Mission Performance and Planning Computer System for Military Helicopter Operations

This paper describes the methodology and technical approach used to develop a portable mission performance and planning computer for military helicopter operations. Advanced development in microprocessor technology, software language, and mathematical techniques are combined to offer a highly sophisticated system which is pilot friendly, lightweight (one pound), compact in size, high speed, and has communication interfaces for ground-based or on-board mission processors. The Computerized Handheld Integrated Mission Performance (CHIMP) system has been developed for a variety of USMC and USA helicopters. CHIMP’S flight management system functionality integrates comprehensive helicopter performance, operating limitations, navigation, and weight and balance capabilities.
