The protected airspace for holding patterns is considered lateral separation. In air traffic management, lateral separation refers to the horizontal distance between aircraft maintaining their defined flight paths. In the context of holding patterns, this ensures that aircraft are adequately spaced apart from one another to prevent potential collisions while they are circling in a designated area.

Lateral separation is essential in managing traffic within holding patterns to ensure that aircraft do not stray into each other's flight paths. This is particularly important as air traffic controllers direct multiple aircraft that may be holding at the same time. Holding patterns are designed with specific dimensions, allowing for safe operation within these confines, and effective lateral separation is a key aspect of maintaining the integrity of that space.

The other types of separation, such as vertical and longitudinal, relate to keeping aircraft at different altitudes or maintaining time-based separations, but in the context of holding patterns, the primary concern is ensuring that lateral distances between aircraft are maintained to avoid conflicts.
