|Abstract:||Inflight pressure pattern navigation was initiated in 1943 when readings of an aircraft’s pressure and radar altimeters were first used to determine its so-called “Bellamy Drift” and/or pressure lines of position. This led to preflight planning of single-heading flights and optimum flight planning based on the patterns of the contours of constant-pressure upper-air charts. The manually constructed “4-D” charts for such manual flight planning have since been replaced by numerical weather predictions that are used in computerized flight planning. Such flight planning is complicated by a lack of coordination among the ways vertical positions are related in aeronautical and meteorological practice that might well be alleviated by tailoring prognostic pressure pattern data for aeronautical use.|
