What type of aircraft must give way to airships, gliders, and balloons?

Power-driven aircraft must give way to airships, gliders, and balloons because of the regulations that prioritize the right of way based on the maneuverability and operational characteristics of the aircraft involved. Airships, gliders, and balloons are typically slower and less capable of executing evasive maneuvers compared to power-driven aircraft. This hierarchy in give-way rules is established to ensure safety in the airspace, allowing the less maneuverable aircraft to maintain their paths without the increased risk of collision caused by faster power-driven aircraft changing theirs.

In air traffic management, such distinctions are essential. For instance, power-driven aircraft, such as those with engines, usually have more options for altitude and speed adjustments. By ensuring they yield to other types of aircraft that are more limited in their ability to navigate rapidly, the regulations create a balanced and safe operating environment in shared airspace.
