ABSTRACT:
An electronic computer having a limited stored program capability and adapted to perform a plurality of problems particularly useful to aircraft pilots. The unit includes an electronic calculator and a stored program controller for instructing the calculator. The programs stored in the controller cause sequential operation, including the demand for manual entry of necessary data, to calculate a desired result. The calculator includes a plurality of program selector keys operative upon the program controller for selecting the program associated with the desired result. The operating panel further includes a plurality of data entry indicators adapted to be illuminated by the controller for indicating to the operator the nature of each data entry required. The calculator is programmed to solve at least each of the following navigational and performance problems: effects of winds aloft on aircraft progress and maintenance of course, and effect of nonstandard atmospheric conditions on aircraft performance. Additionally, the calculator is adapted to perform program controlled functions involving time related problems characterized by two entry multiplication or division functions. Accordingly, the calculator may be efficiently used in preflight planning to establish a flight plan, and in flight to check progress against the flight plan, the simplified operation requiring minimal operator attention, thereby leaving the pilot free to fly the aircraft.
