When two aircraft of the same category approach an airport, which aircraft has the right-of-way?

The correct answer is that the aircraft at a lower altitude has the right-of-way. According to aviation regulations, when two aircraft are approaching to land or are in the same airspace, the general rule is that the aircraft at the lower altitude has priority. This rule is established to promote safety and reduce the risk of collisions, especially in scenarios where aircraft may be converging on the same landing strip or airspace.

Altitude helps maintain separation among aircraft, and the lower aircraft is often maneuvering for landing or is in a more confined space requiring particular attention to its flight path. Hence, this regulation reinforces a clear protocol that helps pilots and air traffic control manage aircraft movements effectively.
