Figure 4-4 Drift Correction
If the drift correction is sufficient, the aircraft will remain on course. If the drift correction is not
sufficient, the wind will blow the aircraft off course in the same direction as before. In this case
repeat the procedure, leaving in a larger drift correction.
If the drift correction is too great for the wind, the aircraft will fly itself off course and the
bearing pointers will drift off in the opposite direction. Turn the aircraft to intercept the desired
course. When the bearing pointer returns to course, establish a smaller drift correction.
Once the proper drift correction has been determined, maintaining the proper heading will keep
the aircraft on course. Continue scanning the bearing pointer and CDI for subsequent changes,
making corrections as necessary.
COMMON ERRORS
1.
Not establishing the aircraft on the proper radial before starting tracking procedures.
2.  Attempting to continue tracking procedures when the aircraft gets off course due to poor
heading control. If this happen, get the aircraft on the proper radial and start all over again.
3.
Forgetting to leave in a drift correction.
4.
Using excessive heading corrections close to the station.
5.  Confusing the difference between intercepting and tracking a course. Use an intercept to
get on the desired course. Tracking is a procedure, which uses a drift-corrected heading in order
to maintain a desired course. Tracking cannot be commenced until the aircraft is established on
course.
6.
Not utilizing the CDI to recognize early deviations due to wind.
