What is the minimum radar separation provided between aircraft established on the same localiser course, disregarding additional longitudinal separation for wake turbulence?

The minimum radar separation provided between aircraft established on the same localiser course is 2.5 nautical miles. This specific separation standard is designed to reduce the risk of collision and maintain safe operational distances when multiple aircraft are on intersecting flight paths.

In practice, 2.5 nautical miles offers a sufficient buffer to account for potential variations in aircraft performance and navigation accuracy. While 2 nautical miles might seem adequate in some circumstances, the additional half nautical mile is crucial in ensuring safety, particularly in areas of heavy traffic or where turbulence might be a factor.

Moreover, this 2.5 nautical mile separation adheres to established air traffic control protocols that prioritize safety and the orderly flow of air traffic. Therefore, using this minimum requirement supports effective airspace management and enhances overall flight safety, especially when considering the influences of wake turbulence and other operational factors that can arise in close-proximity airborne situations.
