What is the recommended length for a pigtail in safety wiring?

The recommended length for a pigtail in safety wiring is between 1/2 and 5/8 inches long. This length ensures that there is enough wire available for a secure loop that can accommodate the necessary twists while maintaining effective tension. A pigtail that is too short can lead to insufficient gripping and may not hold the components securely in place. Conversely, a pigtail that is too long may become prone to being snagged or damaged, leading to potential safety hazards. Therefore, the 1/2 to 5/8 inch length strikes a balance between effective fastening and practicality in various aviation applications.
