Which value should be used if the DME divergence falls between two values?

When determining the appropriate value to use for DME divergence when it falls between two values, using the greater value is significant for several reasons. DME divergence refers to the difference in distance measured by Distance Measuring Equipment (DME) as an aircraft approaches a navigation aid.

Choosing the greater value when dealing with divergence ensures a more conservative approach to navigation, which is crucial in air traffic management. It helps in maintaining safe separation standards between aircraft and ensures that any navigational uncertainties are minimized. This approach reflects a commitment to safety, particularly in environments where precision is vital, such as in controlled airspace.

Utilizing the lower value or an average may not provide adequate safety margins, especially in busy air traffic zones. Likewise, opting for any of the two values without consideration of the specific situation could lead to inconsistent navigation practices and potential operational risks. Therefore, adopting the greater value is aligned with best practices for ensuring safety and accuracy in aviation operations.
