Under what condition is the right-of-way determined between two same-category aircraft?

The determination of right-of-way between two same-category aircraft is primarily based on altitude. When two aircraft are on a collision course or are approaching each other, the aircraft at the lower altitude has the right-of-way. This rule helps to ensure safe separation and prevents accidents during flight, especially in uncontrolled airspace where there may not be air traffic control to assist with guidance.

When operating under these conditions, it's critical for pilots to maintain situational awareness and to adhere to this regulation to manage their flight paths effectively. By ensuring that the aircraft at a lower altitude yields to the one at a higher altitude, the chances of mid-air collisions are significantly reduced, which is essential for maintaining safety in aviation operations.

While factors such as fuel or air traffic regulations may have other influences on flight operations, they do not take precedence over the established altitude-based right-of-way rules when considering two aircraft in the same category.
