FAR Ninety-One Point One Thirteen, the Right-of-Way Hierarchy, and Why a Hot Air Balloon Outranks Every Powered Aircraft in the Sky

Learn how FAR 91.113 ranks every aircraft type for right-of-way priority - and why a hot air balloon outranks every powered aircraft in the sky.

FAR 91.113 establishes the complete right-of-way hierarchy for aircraft operating in U.S. civil airspace. The rule is built around a single organizing principle: the aircraft with the fewest options to resolve a conflict gets priority. That logic explains why a drifting hot air balloon outranks your powered aircraft every time.

What Is the Complete Right-of-Way Hierarchy Under FAR 91.113?

The hierarchy runs from most to least absolute priority. First is distress - any aircraft in an emergency holds right-of-way over every other aircraft in the sky, without exception. After that, the hierarchy by aircraft type is:

  1. Balloons
  2. Gliders
  3. Airships
  4. Aircraft towing or being towed
  5. Powered aircraft

Powered aircraft sit at the bottom. That is not a penalty - it is a recognition that powered aircraft have the most options and can most reasonably absorb and resolve a conflict.

Why Does a Hot Air Balloon Outrank Every Powered Aircraft?

A balloon has virtually no ability to maneuver. A balloon pilot can adjust altitude by working the burner or venting gas and can ride different wind layers at different heights, but cannot turn to avoid traffic. There is no throttle to push, no control surfaces to deflect. The balloon goes where the atmosphere takes it.

The regulation acknowledges that physical reality. When a balloon is anywhere near your flight path, you yield - regardless of how well your approach is going or how close you are to the runway.

Why Do Gliders Have Priority Over Powered Aircraft?

A glider has more maneuverability than a balloon but no engine. Once established on final approach or committed to a landing area, a glider cannot go around. It cannot add power to climb away from a developing conflict.

The hierarchy rewards the aircraft with the fewest remaining choices. A glider’s decision window closes earlier and more finally than any powered aircraft’s. When a glider is in your traffic pattern, you are the one who goes around.

What About Airships and Towing Aircraft?

Airships - blimps and dirigibles - rank above towing aircraft and all powered aircraft. They are large, slow, and have limited maneuverability. An unusual encounter at most airports, but the rule exists.

Aircraft engaged in towing have right-of-way over powered aircraft that are not towing anything. A banner tow operation runs at low altitude, low airspeed, with a long trailing load that punishes any abrupt control input. A towplane retrieving or releasing a glider is equally constrained. Give these operations room and give them priority.

Who Has Right-of-Way When Two Aircraft Are Both on Final Approach?

When two aircraft are both on final for the same runway, the aircraft at the lower altitude has the right-of-way. The higher aircraft yields.

The regulation is explicit about one thing you cannot do: descend below an aircraft already established on final to claim priority. If the other aircraft is properly established and got there first, you work around them. The rule exists to prevent conflicts - not to create a mechanism to cut in line by diving underneath someone.

How Do Converging Aircraft Determine Right-of-Way?

Converging at the same altitude: The aircraft on the right has the right-of-way; the aircraft on the left yields. This mirrors familiar road traffic rules and applies quickly under pressure without working through a decision tree.

Head-on encounter: When two aircraft approach each other directly at the same altitude, both alter course to the right - not one, but both. Each passes on the other’s left side. A true head-on encounter is rarer than it sounds because most flight paths intersect at angles, but when it happens, both pilots go right immediately.

Overtaking: If you are overtaking a slower aircraft, you yield to the aircraft being passed. Alter course to the right to pass and stay right until well clear. The aircraft ahead does not have to do anything.

What Are the Biggest Right-of-Way Misconceptions?

Faster aircraft do not have priority. There is no speed-based priority anywhere in FAR 91.113. A slow Champ on final has the same right-of-way as a fast Mooney on final.

Larger aircraft do not have priority over smaller ones within the same category. Aircraft type category matters; size within a category does not. A Cessna 172 on final and a King Air on final have identical right-of-way under the same circumstances - the one at lower altitude wins.

Military aircraft in civil airspace are not exempt. Military aircraft operating in civil airspace are subject to the same right-of-way rules as any other aircraft. The regulation provides no special military priority outside designated airspace.

Does Having Right-of-Way Mean You Can Hold Your Course?

No. FAR 91.113 explicitly states that right-of-way rules do not give any pilot the right to create a collision hazard or to fly in a careless or reckless manner.

If you have the right-of-way and the other aircraft is not yielding, you still maneuver to avoid the collision. Holding your course out of principle while two aircraft converge is not what the regulation authorizes - it is a choice to accept a midair because you were technically correct. If breaking off your approach is what it takes to avoid a conflict, you break off and sort out the regulation after you are safe.

How These Rules Apply in Real Traffic Pattern Scenarios

Scenario 1: You are turning downwind at an uncontrolled field and hear another aircraft call a long final for the same runway. That aircraft is at lower altitude and established on final - it has right-of-way over you. Extend your downwind, let them land, and sequence behind them. Make a position call so other traffic knows what you are doing.

Scenario 2: You are on base turning final and spot a glider on a long final for the same runway. Gliders have right-of-way over powered aircraft. Go around, extend your downwind, and give the glider the runway. The glider cannot go around. You can. That is the exact logic built into the hierarchy.

Scenario 3: You are on final and a hot air balloon is drifting across the approach corridor a few hundred feet above pattern altitude. Do not continue the approach into the balloon’s airspace. Go around, establish lateral separation, and give the balloon a wide berth. Balloons are large and difficult to judge for distance at low angles, they carry passengers, and they hold the highest right-of-way priority in civilian airspace.

Right-of-Way Is a Last Resort, Not a Strategy

The right-of-way rules tell you what to do when a conflict has already developed. They do not replace situational awareness, good radio technique on the CTAF, or active scanning. The goal is to never reach the point where you need to invoke right-of-way at all.

Build the habit of mentally tracking all traffic from the moment you tune the CTAF - noting where everyone is and what the right-of-way situation would be if they converged with you. The pilot who resolved a developing conflict from a mile out with a clear radio call did not need the rule. That is the standard.

If you are ever genuinely unsure who has priority in a developing situation, give way. The thirty seconds added to your pattern is worth nothing compared to the alternative.

The Airman Certification Standards for the private pilot practical exam tests this material two ways: written scenarios on the knowledge test, and real-time application during the checkride. Examiners watch your scan, your radio calls, and how you sequence yourself at uncontrolled fields. They are looking for a pilot who has internalized the system well enough to apply it naturally under real conditions - not one who has to think through a decision tree while the geometry is getting tight.


Key Takeaways

  • Distress takes absolute priority - any aircraft in an emergency has right-of-way over every other aircraft, no exceptions.
  • The hierarchy: balloons → gliders → airships → towing aircraft → powered aircraft. Powered aircraft sit at the bottom because they have the most options to resolve a conflict.
  • On final approach, lower altitude wins. You cannot descend below an established aircraft to claim priority.
  • Converging at the same altitude: yield to the aircraft on your right. Head-on: both turn right. Overtaking: pass to the right, the aircraft ahead has right-of-way.
  • Right-of-way does not authorize reckless flying. If the other aircraft is not yielding, you maneuver anyway. Safety is the goal; right-of-way is the structure that supports it.
