- right of way
- Refers to the responsibility of each pilot of an aircraft to take all possible measures to avoid a collision with another aircraft. Some rules regarding the right of way are universal. Generally, the order of right-of-way priority is balloons, gliders, airships, flying machines towing anything, and flying machines. Airships will give way to gliders, and gliders to the balloons, etc. When two aircraft are converging in the air at approximately the same altitude, the aircraft that has the other on its right should give way (i.e., the aircraft on the right has the right of way). If two aircraft are approaching head-on, each will turn to the right. When overtaking, the overtaking aircraft must turn to the right and keep out of the way until it has overtaken the other aircraft. Gliders may, however, turn in either direction. The aircraft in front has the right of way. An aircraft landing or on the final approach has priority over all other traffic except seaplanes on the water. If two or more flying machines are approaching at the same time, the aircraft at the lower altitude has the right of way but cannot cut in front of or overtake another that is on final approach. An aircraft in an emergency has the right of way. On the ground, if two aircraft are approaching head-on, each will alter its heading to its right. In the case of converging aircraft on the ground, the one on the right has the right of way, and the aircraft being overtaken has the right of way.
