This page is just a summary. Be sure to download the full rules from the PDF at the bottom of this page.

General Information

You will select your competition class upon registration. Competition classes are outlined in Appendix A. Please contact us prior to registration if you are unsure of the class in which you should compete.

Registration fees are NON-REFUNDABLE. 

Pilots may compete in multiple aircraft but must be able to do so in a way that does not hinder the competition. A registration fee will be charged for each aircraft. 

Pilots may share an aircraft, but each pilot’s score will count for that competitor. Each pilot must pay his or her own registration fee.

Each event has a separate registration closing time. No late registrations will be accepted.

Each pilot and volunteer must sign a liability waiver prior to each event.

Helmets

Whether you’re flying around your ranch, or in our competition, be prepared! We highly recommend that you wear a helmet! Grab one from your favorite supplier or athletic store! Helmets will become mandatory in future seasons.

Shoulder Harnesses

Just like Helmets, Shoulder Harnesses save lives. If you are competing, you should have a shoulder harness in your airplane. Shoulder Harnesses are strongly recommended, but will become mandatory in future seasons.

Unlimited Class

• New in 2023 is the creation of an Unlimited Class, an open class for any pilot and any airframe to join. 
• The class is scored in feet (distance) and follows traditional scoring.
• Each aircraft gets at least 3 runs to score the shortest total distance. 
• Tires must be marked with a yellow line, such as tape, no less than 3 inches long, perpendicular to the edge of the tire. 
• Helmets and shoulder harnesses are required to be worn by competitors in the unlimited class.

Rookie Class

The Rookie class is an optional, relaxed class for all aircraft models and types (as long as they fit into a traditional standard class, i.e., no helicopters or twins) for new competitors. Rules in the Rookie class are relaxed and if time allows, pilots in this class may have a separate practice session ahead of the competition. Competitors may continue to participate in the Rookie class until they place first in the class. The Rookie class has no prizes and no season points. 

The goal of the Rookie class is to educate newcomers to the series and encourage them to grow as pilots. While pilots should be experienced aviators in their aircraft type, this will help them learn the National STOL competition format and standards in a fun, low-stress environment.

Season Scoring-Points System

At the end of the season, an annual champion will be named in each competition class. The annual champion is determined by the number of points accumulated at individual events throughout the year, as outlined below. Please note: You do not have to be present at the final event (“annual championship”) to win; however, points earned at this event will be added to the existing standings. 

Point Earned by Placement (Within Class)
1st	2nd	3rd	4th	5th	6th	7th	8th	9th	10th
25	18	15	12	10	8	6	4	2	1

Each competitor will accumulate season points for the Class(es) in which they compete. If a competitor moves back and forth between the Unlimited and Standard Classes throughout the season, they will accumulate points in both Classes. For example, if a competitor competes in the Unlimited Class and places 1st, they would earn 25 points in the Unlimited Class. If they compete and place 2nd in their Standard Class at the next event, they would have 25 points in the season standing for the Unlimited Class and 18 events in their Standard Class. Points do not transfer in between Classes.

The most consistent competitor of the event will earn 1 additional point toward the season standings. Most consistent is determined by the competitor with the lowest average variation between all rounds AND no DQs.

Pilot Performance Index 

The PPI Winner of each event shall be determined by a Pilot Performance Index. This is scored based on the winning total score by the class leader, as compared to the class leader of the shortest distance (including unlimited class).  See the attached rules sheet for details.
