What is an Ultralight Aircraft?
A true ultralight aircraft is a lightweight, small, and typically single-seat airplane designed for recreational flying. People like these aircraft for their affordability, ease of use, and the fact that many models do not require a pilot license. However, in the USA, ultralight aircraft must meet specific FAA regulations. For example, a true ultralight cannot exceed the maximum empty weight of 254 pounds or a top speed of 63 mph (55 k/ph).
Although we don’t train ultralight pilots here at Epic, I am often asked about them and thought it would be helpful to address them in this article. Under FAA Part 103 regulations, ultralight aircraft are subject to specific requirements to qualify as true ultralights and avoid certification as light-sport aircraft (LSA) or experimental aircraft. I’ll clarify these distinctions below.

4 Types of Ultralight Aircraft
1. Single-Seat vs. Two-Seater Ultralights
- Single-seat ultralight aircraft are the more common. Typically, they do not require a pilot license.
- Two-seater ultralight aircraft are often classified in the light sport aircraft (LSA) category, which requires additional certifications. I share more on LSAs later.
- Single-seat vs. two-seat ultralight: Although I’m oversimplifying here, single-seat models have fewer restrictions, while two-seaters provide the option of carrying a passenger or flight instructor. Read on for more details.

2. Amphibious Ultralights
As you probably have guessed, an amphibious ultralight can land on and take off from both water and land. However, less than 5% of ultralights sold are amphibious. One reason for this may be the extra weight from the floats. If too heavy, it could exceed the limitations for the ultralight classification.
3. Gliders & Motorized Ultralights
- Gliders rely on air currents instead of engines to fly. Without a motor, pilots must be highly skilled and knowledgeable about thermals and wind currents to maintain flight control and altitude.
- Motorized ultralights use small engines and propellers. This offers better control and longer flight times, so they are considered more user-friendly for beginners.
4. Experimental & Microlight Aviation
- Experimental ultralight aircraft allow for customization and innovation. Pilots and designers can test new technologies and are not required to have airworthiness certification.
- Microlight aviation refers to small, lightweight aircraft that can be fixed-wing, flex-wing, and autogyro. They developed from the concept of a hang glider and are subject to specific regulations by civil aviation authorities.

Differences Between Ultralight and Light Sport Aircraft
An ultralight aircraft is generally lighter and comes with stricter limitations compared to a Light Sport Aircraft (LSA). In other words, an LSA is typically heavier, offers more capabilities, and requires the pilot to hold at least a Sport Pilot certificate. An ultralight typically doesn’t require a specific pilot license (depending on the jurisdiction). While both are small, basic airplanes with limited performance, LSAs offer more versatility and features than ultralights. Key differences include:
- Weight: Ultralights are much lighter than LSAs. They come with stricter weight limits that are regulated.
- Pilot Certification: Operating an ultralight typically does not require a specific pilot license in many regions. However, the FAA requires at least a Sport Pilot certificate to fly an LSA.
- Complexity: LSAs tend to have more advanced features and capabilities compared to basic ultralight designs.
Ultralight Aircraft Features & Components
- Wings: These can be fixed-wing, flexible-wing, or autogyro designs.
- Propeller & Motor: Either gas-powered or electric, engines are typically small and lightweight.
- Landing Gear: This varies and can be tricycle (trike) wheels for land, floats for amphibious aircraft, or skis for snowy environments.
- Parachute System: Many ultralights come with a ballistic parachute as an added safety feature.
- Tires & Brakes: These are essential for safe landings and takeoffs.
- Control System: This typically includes a control bar or stick that manipulates the wing’s angle of attack to control pitch, rudder pedals to steer (yaw), and some aileron control all working together to ensure smooth maneuverability and flight stability.
- Plan & Design: The design phase is critical in determining the performance, weight, and aerodynamics of an ultralight aircraft.

FAA Part 103 Regulations
Only single-seat ultralights are allowed under Part 103. The FAA does not require registration or an airworthiness certificate. Night flying is prohibited unless the ultralight is equipped with proper lights. Flight is allowed in Class G airspace. However, to fly in Class B, C, D, and E, pilots must be cleared by ATC. Read on for full regulations:

Do You Need a Pilot License to Fly an Ultralight Aircraft?
In the United States, a pilot license is not required for single-seat ultralight aircraft that meet FAA Part 103 rules. However, if your aircraft exceeds these limits, you may need ultralight aircraft training or an LSA certification. For example, the FAA has different regulations for two-seaters, heavier planes, or faster models.

Two questions I’m often asked are, “How far can an ultralight aircraft fly?” and “What is the fuel efficiency of ultralight aircraft?” The first, like other aircraft, depends on fuel capacity, wind conditions, and the aircraft’s efficiency, but the average is 100 miles. The second is easier to answer: An ultralight typically gets 10 to 30 mpg depending on weight and aerodynamics. -Ray Altmann, Chief Flight Instructor at Epic Flight Academy

- Registration and Certification: The FAA does not require registration or an airworthiness certification.
- Flight Restrictions: The FAA approves daytime operations only (no night flying) unless the aircraft is equipped with proper lights. Also, pilots cannot fly over congested areas, busy airports, or restricted airspace without permission.
- Passenger Restrictions: Under Part 103, the FAA only allows single-seat ultralights. Two-seat ultralights must be registered as Experimental Amateur-Built (EAB) or Light-Sport Aircraft (LSA).
- Operations & Airspace Limitations: Ultralights are allowed in Class G (uncontrolled airspace) without restriction. To operate in controlled airspace (Class B, C, D, and E), pilots must receive prior approval from Air Traffic Control (ATC).
Safety, Crashes, & Legal Considerations
1. How Safe are Ultralight Aircraft?
Are ultralight aircraft safe? With proper maintenance and training, ultralights are as safe as any small aircraft.
- Modern ultralight designs prioritize safety. Many include additional safety features, such as parachutes.
- Proper training and maintenance can significantly reduce crash risks. Therefore, even though the FAA doesn’t require pilot certification, training is still encouraged.
2. Ultralight Aircraft Crash Risks
- The majority of accidents result from pilot error or mechanical failure.
- The FAA recommends regular inspections, maintenance, and proper training to enhance safety.
- Check tire conditions to ensure safe takeoffs and landings.
- Regularly conduct break system checks to prevent mechanical failures.
3. Ultralight Laws and Regulations
Do ultralight aircraft need registration? Under FAA Part 103, they generally do not. However, local rules may apply, so check with your local FSDO (Flight Standards District Offices).
- FAA Part 103 rules govern single-seat ultralights. Pilots must understand and ensure compliance with federal and state aviation laws.
- Ultralights cannot fly over congested areas like cities or town.
- Ultralight aircraft laws can vary by state. Some states have additional restrictions beyond FAA guidelines. For example, here in Florida, ultralight landing areas must have a runway safety area that is 300 feet long and 150 feet wide.
- Lessons and training are not mandatory. However, taking lessons can greatly improve safety and handling skills.
Ultralight Organizations
