During a turning rejoin, how is the line spacing for number 2 designated?

During a turning rejoin, the line spacing for the number 2 position is designated as 3 Aircraft Annotations (AA), commonly referred to as “SA” or “star in the saddle.” This terminology helps pilots maintain appropriate separation between the lead and wingman during maneuvers.

The reason this specific distance is crucial is that it allows for adequate separation while still keeping the aircraft close enough for effective visual and formation reference. The 3 AA distance is an intermediate spacing that balances safety and the ability to respond to the lead's actions during the rejoin.

Other spacing options such as nose-to-tail distances or varying ship widths do not provide the same defined and actionable visual cues needed for a safe and effective turning rejoin. The use of 3 AA is standardized within formation flying protocols, ensuring consistency across different flight crews and enhancing operational safety.
