Right-of-Way Rules and Collision Avoidance

12 chapters · glossary

Right-of-way rules only matter in the moment if a pilot has actually seen the other aircraft in time to act on them, which is exactly why this guide covers both the rules themselves and the visual scanning technique that makes seeing traffic in the first place possible. Neither half is complete without the other.

1. The Fundamental Rule: See and Avoid

Regardless of right-of-way status, every pilot operating under visual conditions bears responsibility for seeing and avoiding other traffic, right-of-way rules resolve who should yield in a given encounter, they don't excuse either party from maintaining a vigilant lookout. This distinction, right-of-way versus responsibility to see and avoid, is the single most important concept in this entire topic.

2. The Category Hierarchy

CategoryYields to
Aircraft in distressHas right-of-way over all other air traffic
BalloonRight-of-way over airship, glider, and powered aircraft
GliderRight-of-way over airship and powered aircraft
AirshipRight-of-way over powered aircraft
Aircraft towing or refueling anotherRight-of-way over other powered aircraft
Powered aircraftYields to all of the above

The underlying logic favors aircraft with less maneuverability or more constrained options, a glider can't add power to climb away from a conflict the way a powered aircraft can.

3. Head-On Approach

When two aircraft are approaching each other head-on, or nearly so, neither has right-of-way; each pilot is required to alter course to the right. This mirrors the same "keep right" convention used in many other transportation contexts, and its predictability is exactly what makes it work, both pilots turning right resolves the conflict, either pilot turning left could put them on a worse collision course.

4. Converging Aircraft

When aircraft of the same category are converging at approximately the same altitude, the aircraft to the other's right has the right-of-way; the other aircraft must give way, generally by turning to pass behind rather than attempting to cross in front. Different-category aircraft follow the hierarchy from Chapter 2 instead, regardless of relative position.

Common Trap Even when you have right-of-way, altering course to give extra clearance if the other pilot doesn't appear to be yielding is the safer choice; right-of-way describes a rule, not a guarantee the other pilot has seen you or will comply.

5. Overtaking

An aircraft overtaking another has no right-of-way and must alter course to the right to pass well clear, the aircraft being overtaken has right-of-way and should maintain its heading and altitude. This applies because an aircraft directly ahead may have no way to see one approaching from behind, which is exactly why the responsibility falls on the overtaking aircraft to maneuver, not the one ahead.

6. Landing Priority

Among aircraft approaching an airport to land, the aircraft at the lower altitude generally has right-of-way, but this doesn't authorize cutting in front of another aircraft on final approach, or overtaking it, purely by descending below it. This specific caveat exists because "lower altitude has priority" could otherwise be exploited to unfairly jump a landing sequence.

7. Right-of-Way Isn't a License to Not Look

Having right-of-way describes a legal and procedural rule for who yields in a specific encounter, it says nothing about whether the other pilot has actually seen you, is paying attention, or will comply. Flying as if right-of-way guarantees safety, rather than treating it as one input alongside continued visual vigilance, is a well-documented contributing factor in midair collisions.

Why This Matters to a Pilot "I had the right-of-way" is not a useful outcome if a collision still happens. The rules exist to make encounters predictable and resolvable, not to substitute for actually seeing and reacting to the other aircraft.

8. Effective Visual Scanning

Effective scanning uses a series of short eye movements across small sectors of sky, pausing briefly on each, rather than a continuous sweeping motion, since the eye can't focus effectively while moving and a continuous sweep effectively sees nothing in sharp focus the entire time. A systematic pattern (moving across the windscreen in blocks, then repeating) covers more sky more effectively than random, unstructured glancing.

9. Blind Spots and Aircraft Design

Every aircraft has structural blind spots, wing, fuselage, and door posts specifically, and high-wing versus low-wing designs create different blind spots relative to the ground and sky. Clearing turns (a shallow bank left and right) before maneuvers, and deliberately moving your head and body to look around structural obstructions rather than only straight ahead, compensate for blind spots a static scan pattern alone would miss.

10. Traffic Advisories and Technology

ADS-B traffic displays (see our ADS-B guide) and ATC traffic advisories are valuable supplements to visual scanning, but neither is complete, unequipped aircraft won't show up on ADS-B, and ATC workload or radar limitations can mean not every target gets called out. Both tools support, rather than replace, an active visual scan.

11. Common Mistakes and Practical Tips

MistakeTreating right-of-way as a guarantee of safety rather than one factor alongside continuous visual vigilance.
MistakeScanning with a continuous sweeping motion instead of short, paused eye movements across sectors of sky.
MistakeNot clearing turns or maneuvering the head and body to check blind spots created by the aircraft's own structure.
Practical TipPractice a systematic scan pattern deliberately, rather than relying on habit, since an unstructured scan tends to skip sectors without the pilot noticing.
Practical TipAlways alter course for additional clearance when in doubt about whether another pilot has seen you, even when the rules say you have right-of-way.

Glossary

See and avoid
The fundamental responsibility of every pilot in visual conditions to see and avoid other traffic, regardless of right-of-way.
Converging
Two aircraft approaching each other's flight path at an angle, at approximately the same altitude.
Overtaking
An aircraft approaching another from behind and to one side, at a faster speed.
Clearing turn
A shallow bank left and right before a maneuver, used to visually check for traffic in blind spots.
