Wind distributions are investigated with a view toward designing some easily applied methods to provide reliable estimates of wind aid or equivalent winds for airborne craft. The Contingency and the Standard Vector Deviation Wind Roses are used.

Wind data at Nashville, Tennessee, at the 300 millibar pressure level and during the winter season are utilized to demonstrate the use of graphical methods. The Wind Aid values obtained graphically from the Nashville data are found to be acceptable as estimates of the computed values. In addition, data at other points are tested. The results corroborate the Nashville study.

Graphical procedures which employ the Contingency or the Standard Vector Deviation Wind Roses, therefore, do provide easily applied methods for providing reliable estimates of wind aid for aircraft.
