When two aircraft are at the same altitude, what determines which aircraft has the right of way?

The determination of which aircraft has the right of way when two are at the same altitude is governed by specific aviation rules and practices. The correct answer highlights the principle that when two aircraft are converging, the one that has another on its right must give way. This rule is based on the need for clear and predictable right-of-way guidelines to minimize the potential for collisions in the air.

This right-of-way rule helps maintain safe distances and avoid misunderstandings between pilots. When two aircraft are approaching each other, understanding which one should yield is crucial for flight safety, making this guideline essential. It is important that pilots are aware of these conventions and comply with them to ensure smooth and safe operations in the airspace.

In contrast, the other options do not reflect the established rules of right-of-way in aviation. Factors such as the number of passengers or the size of the aircraft do not dictate which has priority. The scenario involving final approach can also be misleading because it does not address horizontal encounters at the same altitude. Therefore, understanding the right-of-way rule concerning an aircraft that has another on its right is critical for pilots navigating aviation traffic.
