When marking a no-drop symbol, how many VS-17 panels are used?

The correct number of VS-17 panels used to mark a no-drop symbol is eight. This practice is standardized to ensure visibility and clarity for aircrews, particularly in situations where it is crucial to communicate that a drop should not occur in the designated area.

Using eight panels allows for a more prominent and easily recognizable symbol from a distance, which is essential during operations where safety and coordination are paramount. The configuration of the panels must create a clear visual signal that can be understood under varying conditions, including variable weather or within complex operational environments.

The specific number has been determined through training and operational feedback to balance visibility with resource management. Having eight panels effectively communicates the no-drop message while maintaining a standard that jumpers and pilots are trained to recognize and respond to.
