Final answer:
When two aircraft are converging at the same altitude, the general rule dictates that the aircraft on the left must give way to the aircraft on its right, except when it involves balloons, gliders, or towing/refueling aircraft.
Step-by-step explanation:
When two aircraft are converging at approximately the same altitude, the right-of-way rules state that the aircraft that has the other on its right should give way. This is a general rule applicable worldwide to prevent collisions and ensure flight safety. However, there are exceptions to this rule. For instance, balloon aircraft, gliders, and towing or refueling aircraft have the right-of-way over powered aircraft, making it necessary for the powered aircraft to yield regardless of position.
In cases where one of the converging aircraft is a balloon, a glider, or is engaged in towing or refueling operations, the powered aircraft that has the other on its right shall yield the right-of-way. Understanding these rules is crucial for pilots to maintain safety in the skies and avoid incidents.
