Computer flight planning in the north atlantic

Abstract

An electronic computer and communications system, using the IBM 1620, is developed to provide rapid analysis of upper-air winds and temperatures, optimum route and altitude selection, and detailed speed, time, and fuel data for the preflight planning of jet transport operations over the North Atlantic. The computer flight planning process, program development and operation, facility requirements, meteorological data input, and program capabilities are described. Experience in application of the system to planning daily flights of B707 and DC-8 aircraft for several airlines operating the North Atlantic has demonstrated high accuracy and precision of data handling procedures with reduced exposure to manual errors. The system offers greater flexibility for multiple-plan computation and exploration of alternatives in routes and altitudes, as well as substantial improvements in operating efficiency and economy resulting from increased precision in track determination and optimum plan selection. The potential of a computer flight planning system (CFPS) for application to other areas and services is outlined. It is seen to be an important step in the desired, if not essential, automation of all operations data analysis and planning to keep pace with the advances in technology in navigation, communications, and flight equipment.
