In Figure 2, you would not want to turn at 14.1 DME. You might wait and turn at 14.3 to

14.5 nm to offset the effects of your headwind. The opposite would be true when experiencing a

tailwind. That is, instead of turning at 14.1 you might turn at 13.7 to 13.9 DME. (Figure 3)

Figure 2

Another alternative to the situation would be to turn at 14.1 DME, but use a shallower or

steeper angle of bank as necessary to offset any wind. With a headwind, you would require a

shallower angle of bank than normal. With a tailwind, a steeper angle would be necessary.

Tailwind increases turn radius. Start your turn earlier. Lead point will be earlier.
