What is the minimum DME Divergence Distance for a divergence of 15 degrees?

The minimum DME Divergence Distance helps ensure that aircraft remain safely separated when flying at an angle (or divergence) from a DME (Distance Measuring Equipment) facility. For a divergence of 15 degrees, there are standard calculations used in aviation to determine the necessary distance from the DME to maintain adequate separation.

To compute the minimum DME divergence distance, a common rule of thumb is to take the divergence angle and apply it to a certain formula involving the radius of the earth and the desired angle. For a 15-degree divergence, the minimum distance where the divergence is acceptable is generally found to be around 7 nautical miles. This is essential for maintaining consistent navigational accuracy and safety standards.

Given this, the correct answer is determined to reflect this standard of 7 nautical miles. This ensures that the aircraft flying at this angle maintains adequate separation, thereby promoting safety in the airspace. Consequently, the selected value aligns with regulatory guidance and operational procedures used by air traffic control and pilots.
