What is the least notification the FAA requires before any jump or series of jumps may be made?

The FAA requires that a minimum of one hour's notification is provided before any jump or series of jumps may take place. This regulation is in place to ensure that all jump operations are conducted safely and to allow enough time for the necessary pre-jump checks and preparations to be completed. Pilots, jumpers, and ground crew need this time to properly plan and execute a safe jump, considering factors such as weather conditions, aircraft readiness, and any airspace restrictions that may be in effect.

Having at least one hour's notice helps facilitate communication and coordination among all involved parties, significantly contributing to the overall safety of the skydiving operation. Each jump requires careful consideration of many variable elements, and the allotted time is crucial for ensuring these were thoroughly addressed prior to jumping.
