7.8.3. One of the more common errors made by students is to use the reciprocal of the computed

wind when making compensations. Examples are crabbing left for a wind coming from the right

or slowing down for a head wind component. These simple errors have the effect of doubling the

effect of the wind component. Prevent these errors by estimating the wind and its compensation

prior to working the math.

course errors.

7.9.1.1.1. Standard Corrections: Standard corrections are the most common and only

require the aircraft be a known distance off course. The table in Figure 7-6 illustrates the

standard corrections used for an aircraft traveling at 300 kts ground speed. In Figure 7-6

note the correction for one mile is 10 for 1 minute and is a basis for the other correction
