How should you determine a distance for lateral separation if divergence is between two values in the divergence table?

To determine a distance for lateral separation when the divergence is between two values in the divergence table, using the greater distance is essential for maintaining safety and compliance with spacing standards. The divergence table is a tool that provides specific lateral separation distances based on aircraft positions and their respective trajectories. When there is a range of values presented, selecting the greater distance ensures that the aircraft maintain adequate spacing, thereby reducing the risk of potential conflicts and ensuring safe operation within controlled airspace.

This approach allows for a conservative method of ensuring separation, considering factors such as varying flight paths, airspeed differences, and potential deviations. Using the greater distance acts as a buffer that accounts for any uncertainties or deviations that may occur in flight operations. In contrast, utilizing lesser or average distances may lead to insufficient separation, compromising safety and operational effectiveness.
