It won’t be long before you’ll hear the advice that “It is better to be on the ground wishing you were in the air, then to be in the air wishing you were on the ground”.
These videos demonstrate all of the considerations prior to commencing flight (Courtesy of United States Hang Gliding and Paragliding Association).
For Tandem Pilots:
HPAC has developed a Critical Preflight Checklist (CPC). It represents the final opportunity to check your gear, yourself and your student/passenger before launch. Use it to confirm that you and your passenger are truly ready for take-off and to make last minute adjustments that are better done on the ground than in the air.
