Extract

Based on a survey of its members in Europe and the Middle East, IATA expects that by 1985 almost half their aircraft will be equipped with Flight Management Systems (FMSs) incorporating 2-D, 3-D or 4-D navigational capabilities. The prime aim of this very significant investment is to increase airline operating efficiency, in particular through fuel saving. Flight Management Systems can perform a wide range of tasks, including flight planning and performance management, for which inputs of meteorological data are required. The more sophisticated systems can accept a number of wind and temperature inputs for the climb and descent profiles plus a wind input at each way-point of the cruise phase. Any estimate of flight progress and fuel requirements based on the use of the most economical aircraft speeds, whether made by the pilot or by an FMS, can only be as good as the knowledge of the wind-vector data pertinent to the flight. Whereas FMS-equipped aircraft in level cruise can often ‘update’ or correct the forecast data relating to the next flight leg, this is not feasible when major changes of altitude are necessary, e.g. during the descent phase. Accurate meteorological data are essential to ensure the optimum results from the FMS.

During the early 1970s, before the fuel crisis began, some thought was being given to the problem of handling the rapidly increasing number of aircraft movements in Europe.
