| NOTE WELL: |
|
The FAA Glider Flying Handbook, as it was originally published has an incorrect diagram for the signals for telling the tow plane to turn left, and turn right. This error is corrected in the errata sheet published by the FAA for the Glider Flying Handbook. Figure 7-2 on page 7-3 of the Glider Flying Handbook, FAA-H-8083-13A is incorrect. Please refer to the errata sheet published by the FAA: glider_flying_handbook_errata_13a.pdf |
Completion Standards
When complete, the student will know and be able to demonstrate all of the signals listed above.
