Does the DME Application Table account for DME slant range error?

The DME Application Table is a crucial resource that helps pilots and air traffic controllers account for various measurement errors when using Distance Measuring Equipment (DME). In particular, it incorporates the effects of slant range error, which occurs because DME calculates distance in a straight line from the aircraft to the ground-based DME station rather than the actual horizontal distance traveled. This slant range can lead to inaccuracies, especially at higher altitudes where the vertical distance to the DME station becomes significant compared to the horizontal distance.

By factoring in these errors, the DME Application Table improves the accuracy of distance reporting, helping ensure that pilots have reliable information for navigation and approach. This consideration also assists in maintaining safe separation among aircraft, especially in crowded airspace where precise distance measurements are critical for collision avoidance and traffic management.

Thus, recognizing that the DME Application Table does account for slant range error is essential for proper navigation planning and execution. Understanding this feature allows pilots to use DME data more effectively, improving overall flight safety.
