According to aviation rules, what right is given to an aircraft being overtaken?

The aircraft being overtaken has the right of way under aviation rules, which is consistent with general practices across various types of vehicles. This rule is designed to ensure safety and predictability in the airspace. When one aircraft is overtaking another, the intention is generally clear that the overtaken aircraft is unaware of the maneuver and must have the right of way. This allows the overtaken aircraft to maintain its course and speed, minimizing the risk of collision and facilitating a smooth flow of air traffic.

In this context, the overtaking aircraft must exercise caution and ensure it has enough altitude and lateral separation to safely pass without interfering with the flight path of the aircraft being overtaken. This principle is vital in maintaining operational safety and preventing accidents in crowded airspace.
