FAR Ninety-One Point One Thirteen, the Right-of-Way Hierarchy Every Student Memorizes and Most Pilots Half-Forget, and Why the Lowest Aircraft on Final Wins Every Time

FAR 91.113 establishes the right-of-way rules for all U.S. aviation operations except water. The regulation is built on a single principle: aircraft that cannot maneuver receive the most protection. Memorizing the hierarchy is the starting point - applying it correctly in the pattern is the real skill.

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

The hierarchy runs from highest priority to lowest, based entirely on maneuverability. An aircraft with less ability to yield gets more legal protection. In order:

1. Aircraft in distress - absolute priority over every other aircraft, no exceptions
2. Balloons - outrank all other aircraft, including gliders
3. Gliders - priority over powered aircraft because they cannot add engine power
4. Airships - large, slow, and difficult to maneuver quickly
5. Aircraft towing or refueling other aircraft - tow combinations cannot maneuver aggressively without risking the tow line or destabilizing the towed aircraft
6. Everything else - all standard powered aircraft, including your Cessna, Piper, or Cirrus

Why Does a Balloon Outrank a Glider?

This is the part of the list that surprises most students. A glider pilot can bank, pull, and maneuver. A balloon pilot cannot. A balloon’s horizontal movement is almost entirely at the mercy of the atmosphere - the pilot can adjust altitude by heating the envelope or venting gas, but cannot steer away from a conflict on demand. The regulation protects the aircraft that literally cannot yield.

Balloon operations are most common at dawn and dusk near tourist destinations, wine country, and scenic valleys. If you’re flying cross-country in those environments, a balloon may be drifting at low altitude near a ridge in poor light. Know the rule before you need it.

Who Yields When Two Powered Aircraft Converge?

When two aircraft of the same category converge at approximately the same altitude, the aircraft to the other’s right has the right of way. The aircraft on the left yields.

The word “approximately” matters. If the geometry looks like a conflict and the altitudes are close enough to perceive a risk, give way. The rule produces a consistent, predictable response - if you are converging from the left, you yield, every time. Think of it like a four-way stop: you yield to the vehicle on your right.

What Is the Rule When Two Aircraft Approach Head-On?

When two aircraft approach each other approximately head-on, both pilots turn right. Not the lower aircraft. Not the slower one. Not the one that saw the situation first. Both.

This creates a predictable bilateral response. If both pilots independently turn right, they move in complementary directions and separation grows. If one turns right and one turns left, they could converge again. The rule eliminates that ambiguity - you turn right the moment you recognize a head-on situation, without waiting to read the other pilot’s intention.

How Does the Overtaking Rule Work?

If you are overtaking a slower aircraft from behind, you pass to the right. The aircraft being overtaken holds course and speed - it has the right of way. You are the faster, more maneuverable aircraft, so you do the maneuvering.

Passing to the right means that after you clear the other aircraft, you end up on their right side. When they continue forward on their heading, they will not fly into you.

Who Has the Right of Way on Final Approach?

An aircraft established on final approach or in the landing pattern has the right of way over aircraft in flight and over aircraft on the surface. The workload during approach and landing is already high, and requiring an aircraft on final to execute an aggressive avoiding maneuver at that stage is dangerous.

When two aircraft are both approaching to land, the aircraft at the lower altitude has the right of way - not the one that has been in the pattern longest, and not the one that made the most radio calls. The lower aircraft wins.

Can the Lower Aircraft Cut In Front of an Established Final?

No. This exception is written explicitly into the regulation. The lower aircraft cannot dive beneath an aircraft already on a stable final and then claim legal priority. FAR 91.113 states directly that the lower aircraft shall not cut in front of or overtake that aircraft. The rule gives priority to the lower aircraft, but it does not authorize dangerous maneuvering to manufacture that position.

How Do You Apply This in the Traffic Pattern?

Consider a scenario common on practical tests: you are on downwind at an uncontrolled field, and another aircraft is turning base. Both of you are converging toward short final at roughly the same altitude.

The converging rule applies - same category, similar altitude. If the base-leg aircraft will cross from left to right on your path, it is on your right. It has priority. You extend your downwind, slow down, or execute a go-around to create spacing.

On a busy uncontrolled field with three or four aircraft in the pattern, the legal framework defines who yields when a conflict develops. But good airmanship means not letting the conflict develop at all. Use the radio, announce your position and intentions, and if spacing is going to be tight, extend a leg and create the gap yourself. The regulation defines who yields in a conflict. The judgment to prevent the conflict is yours.

Does Having the Right of Way Mean You Don’t Have to Maneuver?

No. Paragraph (a) of FAR 91.113 states that when weather conditions permit, every person operating an aircraft must maintain vigilance to see and avoid other aircraft - regardless of whether the flight is conducted under IFR or VFR, and regardless of right-of-way status.

Having the right of way does not relieve you of the responsibility to avoid a collision. The right-of-way rules tell you who yields to prevent a developing conflict. They do not excuse you from maneuvering when a collision is imminent. Having the right of way is a legal concept. Avoiding a midair is a survival concept. They are not the same thing.

How Do You Detect a Collision Course?

An aircraft on a pure collision course with you will appear stationary in your windscreen - it holds the same angular position while its apparent size grows. A spot in your field of view that is growing but not drifting laterally is pointed at your nose. React.

A disciplined scan - left to right, low to high, with deliberate pauses in each sector - is your primary detection system. Most midair collisions occur in visual meteorological conditions near uncontrolled airports in daylight, not in clouds or at night. They happen when the sky feels largest and pilots feel most comfortable, which is exactly when scan discipline matters most.

How Do You Read Position Lights to Determine Traffic Geometry at Night?

Night operations require reading position lights to interpret what another aircraft is doing before you can determine who yields:

• Red and green lights together - you are looking at an aircraft pointed toward you. Head-on situation.
• Red light only - the aircraft is showing you its left wing and angling away to your right
• Green light only - the aircraft is showing you its right wing
• White light only - you are looking at the tail. The aircraft is moving away from you.

The red light is on the left wing, green is on the right wing, white is on the tail. Reading those lights correctly at night is a distinct skill from a daytime scan, and it is covered in the ACS night operations task for the private pilot certificate.

What Are the Limits of ADS-B Traffic Displays?

ADS-B In gives you early awareness of traffic your scan might miss, and you should use it. But know its limits. An aircraft without ADS-B Out will not appear on your display. Balloons will not appear. Ultralights without avionics will not appear. The traffic display augments your scan - it does not replace it.

This gap is especially significant given the hierarchy. Balloons sit at the top of the right-of-way list. If your traffic display cannot show you balloons, you cannot rely on it to protect you from the aircraft with the most legal protection under the regulation.

What About Formation Flight?

FAR 91.113 does not apply during formation operations. Formation flight is governed by FAR 91.111, which requires that all pilots of the involved aircraft explicitly agree in advance to any deviation from standard right-of-way rules. You cannot fly informal formation with a stranger and assume the normal rules no longer apply. The agreement must be intentional and specific. This is relevant if you pursue aerobatics training, air racing, or advanced certificate work.

A Mental Checklist for Every Traffic Encounter

When traffic appears, run through this quickly:

1. What category is it? Distress, balloon, glider, airship, tow aircraft, or powered airplane?
2. What is the geometry? Converging left or right? Head-on? Overtaking?
3. Who has priority under the applicable rule? If they have it, yield. If you have it, hold course but stay ready to maneuver.
4. Regardless of the answer above: if a collision is possible, maneuver.

The regulation protects aircraft that cannot protect themselves. Understand that principle and the order of the list becomes something you understand rather than something you memorize.

Key Takeaways

• The right-of-way hierarchy is built on maneuverability: aircraft with the least ability to yield receive the most legal protection.
• Balloons outrank gliders because balloon pilots cannot choose their horizontal path - glider pilots can still bank and maneuver.
• On final approach, the lower aircraft has the right of way, but cannot dive beneath a stabilized final to manufacture that priority.
• In a head-on situation, both pilots turn right - independently, immediately, without negotiation.
• Having the right of way does not eliminate your obligation to avoid a collision. See-and-avoid is unconditional.
