Figure 5-14 Wind Component Breakdown

In each quadrant, to simplify the analysis of wind direction, we assume there are only 5 options

per quadrant (see Figure 5-14). They are all head/tail, 30 off aspect, 45 off aspect, 60 off

aspect, and all crosswind. By limiting our choices to these 5 bearings, determining the wind

direction is a very quick process, and should always be within acceptable standards for this stage

of training.

In this example, lets assume the wind is out of the front right quadrant. After determining the

magnitudes of the components from the 6 minute rule, simply pick the aspect angle that best fits

and assign a magnitude.

Components

Wind direction

All headwind

Nose

30 off aspect

More headwind than crosswind

45 off aspect

Headwind and crosswind are equal

60 off aspect

More crosswind than headwind

90 off aspect

All crosswind
