FAR 91.113 and the Right of Way Hierarchy: The Pecking Order in the Sky That Every Pilot Must Know Cold

FAR 91.113 establishes the right of way rules every pilot must know - not just for the oral exam, but for the split-second decision that happens when traffic appears in the windshield. The hierarchy runs from aircraft in distress at the top, through balloons, gliders, and airships, down to powered airplanes and weight-shift-control aircraft at the bottom. Once you understand the governing principle - less maneuverable aircraft get more protection - the order becomes logical rather than a list to recite.

Why Mid-Air Collision Rules Matter More Than You Think

Mid-air collisions are rare, but they are almost always fatal. The National Transportation Safety Board has analyzed dozens of them, and a consistent finding across those reports is striking: a significant number occur in visual meteorological conditions. Good weather. Unlimited visibility. Both pilots theoretically could have seen each other.

The right of way rules are not a replacement for see-and-avoid. They are a decision framework for the moment when two pilots are doing everything right and still find themselves on a converging path. Knowing these rules means having the answer before the question fully forms.

What Is the Right of Way Hierarchy Under FAR 91.113?

The hierarchy, from highest to lowest priority:

1. Aircraft in distress (declared emergency)
2. Balloons
3. Gliders
4. Airships
5. Airplanes and powered lift
6. Powered parachutes and weight-shift-control aircraft

This is not an arbitrary ranking. Every position in the list reflects how much the aircraft can maneuver out of a conflict.

Why Maneuverability Determines Right of Way Priority

Maneuverability drives priority. That is the entire principle. Once it clicks, the hierarchy becomes derivable from logic rather than memorization.

Balloons sit at the top of the non-emergency hierarchy because they have almost no lateral maneuverability. A balloon pilot can manage altitude within limits, but the aircraft goes where the wind goes. They cannot turn away from a conflict. So the rules protect them.

Gliders are next. With no engine, a glider cannot add power, climb aggressively, or change its energy state on demand. Its options in a conflict are genuinely limited compared to any powered aircraft.

Airships can maneuver, but slowly. Airplanes and powered lift, where most pilots operate, come after. And at the bottom: powered parachutes and weight-shift-control aircraft (trikes) - often among the most agile aircraft in the sky, capable of quick turns and direction changes. Because they have options, they yield to everyone with fewer options.

How Do Converging Aircraft Determine Right of Way?

When two aircraft are on converging headings at roughly the same altitude and neither is overtaking the other, the aircraft on the right has the right of way. The aircraft on the left must give way - the same logic as a ground intersection: yield to traffic on your right.

The practical challenge is geometry. You need to determine whether the other aircraft is on your right or left, and at a distance with a shallow converging angle, that is not always immediately obvious. This is why early traffic acquisition matters: the sooner you spot traffic, the more time you have to resolve the geometry and act.

A critical visual cue: if traffic is not drifting left or right in your field of view - if it is simply getting larger - you are on a collision course. Traffic that drifts laterally will pass clear. Traffic that just grows is the conflict that demands action, regardless of whose right of way it technically is.

What Is the Head-On Rule?

When two aircraft are approaching head-on, or nearly so, each pilot must alter course to the right. Not left. Always right. The rule is symmetrical - both aircraft turn right, both miss each other, no coordination required. If both pilots execute correctly, the conflict resolves without either knowing what the other did.

The regulation uses the phrase “apparently head-on, or nearly so.” If you cannot determine whether you are in a true head-on or a shallow converging situation, treat it as head-on and turn right. That is the conservative and correct call.

How Does the Overtaking Rule Work?

When you are faster and closing on an aircraft from behind, the aircraft being overtaken has the right of way. The overtaking aircraft must give way, and the regulation specifies how: pass to the right of the aircraft you are overtaking.

This surprises some students. The slower aircraft being caught from behind has priority? Yes - because they may not know you are there. Their traffic scan covers the forward hemisphere. Something closing from directly behind may not be visible to them at all. The overtaking aircraft carries full responsibility for the maneuver: you see them, you maneuver, you pass to their right.

What Are the Landing Right of Way Rules?

When two aircraft are both approaching an airport to land, the lower aircraft has the right of way. The higher aircraft must yield. But the regulation adds an explicit limit: the lower aircraft may not use this rule to cut in front of an aircraft already established on final approach or to overtake that aircraft.

Both halves matter. The lower aircraft has priority - but cannot weaponize that position to dive in front of someone already on final. In practice, sequencing should be established long before aircraft are close enough for this to become a conflict. If you are coming in high and someone is below you on final, you extend your downwind, go around, or do whatever is necessary. You do not argue right of way while two aircraft are pointed at the same piece of pavement.

An aircraft on final approach to land also has right of way over aircraft in flight and aircraft on the ground. If you are on base and there is an aircraft on final, they have priority - extend or go around.

The Overarching Principle: No Collision Hazards, Period

Beneath every specific rule in 91.113 is a single statement the regulation makes directly: no pilot may operate in a manner that creates a collision hazard. Having the right of way does not authorize ignoring safety to exercise it. Even the balloon, even the glider, retains the responsibility to see and avoid and to operate safely.

The right of way rules determine who yields in a conflict. They do not relieve any pilot of the duty to prevent a collision.

Applying 91.113 in Real Scenarios

Scenario 1. You are in a Cessna 172 cruising southwest at 3,000 feet. A Piper Warrior is off to your right, converging at roughly your altitude. The Warrior is on your right - the Warrior has right of way. You give way.

Scenario 2. You are in the traffic pattern at a non-towered airport on downwind. A glider enters from the north, setting up for the same runway, and is below you. Two rules point the same direction: gliders have right of way over airplanes by type, and the glider is lower. You extend your downwind and sequence behind them.

Scenario 3. You are established on long final, fully stabilized. Another aircraft cuts across from your right and settles in ahead of you at a lower altitude. Technically lower - but they just created a collision hazard, which the regulation explicitly prohibits. You go around. You announce it on the CTAF if applicable. The regulations are a framework for safe flight, not a sword to assert priority. When someone violates them, your job is to stay safe.

What Your Oral Examiner Expects on This Topic

The Airman Certification Standards for the private pilot certificate test 91.113 from multiple angles. Expect the examiner to describe converging aircraft and ask who yields, present a head-on situation and ask what each pilot must do, or ask you to walk through the type hierarchy. They are checking for two things: whether you understand the underlying principle and whether you know the specific required actions.

Know these four cold:

• Converging: yield to the aircraft on your right
• Head-on: both pilots turn right
• Overtaking: pass to the right of the aircraft you are overtaking
• Landing: give way to the lower aircraft; aircraft on final have priority

See-and-Avoid Is Still the Primary Defense

All of 91.113 assumes you have already seen the traffic. The right of way rules are the decision framework you apply after you have traffic in sight. If you have not seen them, the rules do not protect you.

A disciplined traffic scan matters more than any regulation. Avoid fixating on instruments for long stretches. Clear the sky in segments, systematically. Use your ADS-B traffic display as a supplement - not a primary - and remember that ADS-B only shows equipped aircraft. Not everything you will encounter will appear on that display.

The goal is early acquisition: spot traffic while it is still distant enough that the geometry is clear, the applicable rule is obvious, and you have time to maneuver without urgency. The right of way rules are most useful with a few minutes to think. They are hardest to apply correctly with a few seconds.

On every training flight, practice applying 91.113 in real time to every piece of traffic you acquire: what type of aircraft, what is the geometry, what does the rule require. With repetition, the calculation becomes automatic. That is the goal - not reciting the regulation when asked, but applying it without thinking when it matters.

Key Takeaways

• FAR 91.113 establishes a right of way hierarchy based on maneuverability: less maneuverable aircraft receive more protection.
• The full order: distress aircraft → balloons → gliders → airships → airplanes/powered lift → powered parachutes/weight-shift-control.
• In a converging situation, yield to the aircraft on your right. Head-on, both pilots turn right. Overtaking, pass to the right of the aircraft being overtaken.
• When landing, the lower aircraft has right of way - but may not cut in front of an aircraft already established on final.
• Right of way rules supplement, not replace, see-and-avoid. Early traffic acquisition gives you time to apply the rules correctly.
