Q201: What is an ultralight (or microlight)?
If your viewing software has a search function, you can jump to the desired answer by searching for the question number as in "Q201:". Or, you can browse forward by searching for the "Subject:" line which precedes each answer. The style and format of this document is intended to comply with preferred Usenet conventions.
Subject: Ultralights and Microlights
In the U.S.A. an ultralight is defined in Federal aviation regulations FAR Part 103 (and subsequent advisory circulars) as a *single* seat powered flying machine which weighs less than 254 lbs, has a top speed of 55 knots (63 mph), stalls at 24 knots (28 mph) or less and carries no more than 5 gal. of fuel. Excluded from the empty weight are floats for water landings and safety devices intended for deployment in an emergency. The weight allowance for an emergency parachute is 24 lbs. so an ultralight with a parachute could weigh 278 lbs.
There are strict operating limitations (see question Q202:), but no mandatory license or registration. Special 2-seat exemptions are granted to instructors for training purposes only. These training aircraft can weigh 496 lbs and carry 10 gal. of fuel. All single seat ultralights which exceed the above limits and any 2-seater not used solely for instruction must be registered as an Amateur built aircraft and must be flown by a licensed pilot. Regulations vary outside the USA, but many nations allow more weight, speed, fuel, and 2-seat operations at the expense of more safety requirements. Some call them microlights.
The Canadian Ultralight is defined in Question: Q216
Subject: Ultralight Regulations
Yes! Aside from the vehicle definition (see question 201) there are strict operating limitations (USA) designed to limit the dangers to the non-participant. (You are permitted to risk your own neck.)
Subject: Where can I find Ultralights?
There are several pilot organizations which can help.
The U.S. Ultralight Association is an organization of ultralight pilots and flying clubs in the USA. They administer an ultralight instructor program and voluntary pilot and vehicle registrations. A monthly magazine Ultralight Flying is included with membership in USUA. The magazine is the oldest and largest ultralight publication. It is available only by subscription. You can contact the magazine directly at Ultralight Flying, P.O. Box 6009, Chattanooga, TN 37401. Phone: (423) 629-5375 / Fax: (423) 629-5379. Subscriptions are $30 (US) for 12 issues. (The January issue is the annual buyers guide.)
Contact the U.S. Ultralight Assn at P.O. Box 667, Frederick, MD 21705. Phone (301) 695-9100 or fax (301) 695-0763. Membership is $39.95 (US). The USUA can give you information about flying clubs, instructors, and flight parks in your area.
The Experimental Aircraft Assn. (EAA) is an organization for all types of homebuilt, antique, warbirds, rotorcraft, and ultralight aircraft. They have a very large network of local chapters. Several magazines are available with membership in EAA. Ultralight enthusiasts should chose EAA Experimenter magazine at the $28 per year membership. Their flagship publication, Sport Aviation covers all the different types of sport aircraft with emphasis on the homebuilts for $35 per year. A week-long annual convention and airshow is held in Oshkosh, Wisconsin each summer.
Write to EAA Aviation Center, P.O. Box 3086, Oshkosh, WI 54903 or
Aero Sports Connection is a new organization for ultralights pilots. In addition to conventional ultralights, ASC is attempting to serve the powered parachute, rotorcraft, and balloon pilots etc. They also have instructor, pilot, and vehicle registration programs. A monthly magazine ULTRAFLIGHT is included with the $40 annual membership. Write to Aero Sports Connection. P.O. Box 589, Marshall, MI 49068 or call (616) 781-4021 evenings. Email KIMOjim@aol.com.
Finally, you can go to a small airport in your area (not a major hub), and ask around. There are independent clubs and airparks that are not part of the above organizations. Make every possible effort to locate a flying club near you because a group of pilots can provide invaluable help choosing an ultralight and finding a place to keep it.
Subject: Ultralight Safety
No. Not necessarily. They have a tremendous advantage over regular aircraft due to their low weight and speed. Minor accidents cause little damage and major accidents are less often fatal. As with hang gliders, when they were first being invented, there were many poorly designed ultralights being flown by untrained pilots. Hang gliders and ultralights are now well understood and we know how they should be built and flown.
Is engine reliability a factor? Gliders have no engine and the operators do not consider that a safety factor. Hot air balloons can only barely control their direction. Skydivers go mostly down! Each type of aviation activity must be conducted within its design limits. Accident statistics are difficult to evaluate. Should it be expressed as accidents or fatalities. Do you want it per mile, per hour, per flight, or per pilot. Airlines use seat-miles to get the best possible numbers. All the various types of *established* recreational flying are reasonably safe if you follow good practices.
Subject: Costs of building, buying, learning, flying
Q205: What does it cost to build, buy, learn, fly?
You can build a variety of safe very serviceable ultralights costing from $3000 to $6000. A raw materials kit or construction kit less engine is the cheapest way to start. Plan on spending at least 6 months to 2 years on the project. An assembly kit has all the parts prebuilt and you just bolt it together in a few weekends. Cost of these kits starts at about $6000. You can buy a used or new machine ready to fly for anywhere from $2000 to $15,000. Older models must definitely be inspected by a knowledgeable friend. If you build one yourself, you will naturally be better qualified to maintain it.
There are many ways to learn to fly ultralights. Formal flight training in a 2-seat ultralight from a real instructor can cost $600 to $1200 or more. You could take a few lessons from an instructor or a friend in a conventional aircraft but the speeds and handling characteristics are quite different. It's better than the third option which is no training at all. In the USA it is legal but very stupid to attempt flight with no training whatsoever. Any experience in regular aircraft, sailplanes, hang gliding, or even RC-models is helpful. Much of the ground school such as weather, navigation, engines, safety, and regulations can be learned on your own by reading and study.
Actually flying the ultralight is usually very inexpensive. The engines burn only 2 to 3 gal per hour. Routine maintenance and even a complete engine rebuild is minimal. You could damage a prop ($150) or wipe out your landing gear ($300). Almost all ultralights must be stored under a roof protected from sun and weather. Direct sunlight will destroy some types of fabric coverings ($1000) in as little as 2 years! If you cannot disassemble the ultralight or fold the wings and trailer it home, you will need to rent hangar space if you can find it. Hangar rent can be the largest single operating expense at $30 to $90 per month.
Subject: Weight limits
Many ultralights do exceed the limits though most of them are only a little heavy or fast. Manufacturers design ultralights which just barely qualify so they can offer the most performance and features possible. Some owners then add bigger engines, more streamlining and other options which take it over the limit. The government relies on more or less voluntary compliance because they will never have the resources to hunt down every ultralight that is slightly over the limit. They realize that a little extra weight or speed does not significantly increase the risks involved. However, if you violate the operating limitations (see question 2), and someone reports it, you WILL be fined $1000 for each occurrence. Exceeding those operating limitations very greatly compromises safety.
Subject: Ultralights vs. "real" airplanes
Q207: Why would anyone want to fly these marginal machines when they could be flying *real* airplanes?
First they are not marginal. Ultralights are designed to have the same structural strength as regular normal category aircraft. A major reason people fly them is the lower cost. In spite of what critics might say by comparing the cost of an old worn out conventional aircraft with a new ultralight, the average cost of owning and flying an ultralight is much less than conventional aircraft. Also, some people can never fly *real* airplanes because they can't pass the medical requirements. The most important reason people fly ultralights is because they are FUN ! The slow flight, often open cockpit, and light responsive handling make them more like a motorcycle of the air than car in the sky. One final reason (in the USA) is freedom from excessive regulations.
Subject: Ultralight training for pilots of certificated aircraft
Conventional pilot training is a tremendous asset when learning to fly ultralights but some habits will have to be changed. They have much less mass and inertia and thus do not retain airspeed as long as other aircraft. Control response time is often quicker so the regular pilot may tend to flare for the landing much to early. Also, headwinds and crosswinds have a much greater effect and can more easily spoil your navigation and use up all your fuel. Ultralights really should always be flown such that there is a safe emergency landing area within gliding distance. The pilot should be comfortable making power-off landings. You should get at least a few flights in a 2-seat ultralight and some ground school covering 2-strokes engines and ultralight regulations.
Subject: Pilot requirements for 2-seat ultralights.
Q209: Who can fly a 2-place ultralight?
1.) Probably the most common 2-seat ultralight-type AIRCRAFT is the 51% Amateur-built, registered in the experimental category. These aircraft will have the FAA "N-number" marking on the fuselage or tail, and will have the word "EXPERIMENTAL" near the cockpit where it can be seen by passengers as they enter. The pilot must hold a FAA Private or Recreational license or better. An FAA student pilot could fly such a machine SOLO ONLY, if under the direct supervision of a CFI.
2.) A new type is the 2-seat ultralight-type AIRCRAFT registered in the new Primary category as a "Sportplane". These are FAA certified kitplanes which will have FAA "N-number" markings but do not have the EXPERIMENTAL placard. The Quicksilver GT-500 was the first to qualify. Pilot requirements are the same as above.
3.) The 2-seat exempted ultralight trainer is a special type that can only be used for instruction. It is exempted from the normal pilot and vehicle requirements, provided the pilot qualifies as an official ultralight instructor. The pilot must carry documentation that he has such an exemption, available from the USUA or the ASC as part of their instructor program, or from the EAA, which has a program for CFI's. The instructor is not supposed to use this 2-place machine as his personal recreational vehicle. Finally, the aircraft must be marked "FOR INSTRUCTIONAL USE ONLY".
4.) Lastly, there is the illegal 2-seat ultralight-type AIRCRAFT. If there are no markings on the aircraft of any kind, and it's flying, it is most certainly illegal. If it has two seats, you must see "N-number" markings, or the placard for "INSTRUCTIONAL" use. FAA certificated pilots should avoid flying illegal 2-seat aircraft (even only solo), because they risk losing their license and paying stiff fines. Unlicensed pilots face the same fines, usually multiple $1000 fines for each flight. Passengers are strongly advised to avoid riding in unregistered, 2-seat ultralight-type AIRCRAFT which are flown by unlicensed pilots.
And now one final point. It is not possible to have a convertible or dual purpose vehicle which can be used both as a single seat ultralight and as a 2-seat N-numbered experimental homebuilt depending on it's configuration. While it's theoretically possible to make such a conversion, you must surrender the original aircraft registration and cannot change back and forth at will.
Subject: Ultralight rotorcraft
Yes, there are indeed ultralight gyrocopters which meet all the requirements of weight and speed (USA) to qualify as an ultralight. For more information, contact the Popular Rotorcraft Association, P.O. Box 8756-UF, Clinton, Louisiana, 70722 or phone (504) 683-3545
You absolutely *MUST* obtain instruction to pilot a gyrocopter regardless of your experience in regular aircraft or ultralights. Numerous skilled pilots have learned the hard way that the controls are very much different.
For more information also try these sources:
Helicraft Inc., P.O. Box 50, Riderwood, MD 21139 phone (410) 583-6366 fax (410) 692-5902 offers plans, information ($10), and kits for all kinds of rotary wing aircraft. Most are too heavy or fast to qualify as an ultralight but they do have one ultralight gyrocopter. Plans for a tiny helicopter with jet engines on the rotor tips are available but this craft has never been widely built presumably because of it's VERY high noise level, and probable high fuel consumption. Incomplete plans for an unproven 2-stroke powered UL helicopter are available.
Until recently, It could be said there are a no PROVEN ultralight helicopters in the USA. The weight limit of 254 lbs has been the barrier with the current technology. In 1993, a true ultralight helicopter built using modern composite construction was introduced as a tested, ready to fly helicopter. It has lots of custom built hardware and is powered with a Rotax 503. The price was estimated at $30,000. Contact: American Sportcopter Inc., 812 Middle Ground Blvd., Newport News, Virginia, 23606.

Subject: Powered paragliders and other types
Ultralight powered parachutes (parafoils, paragliders) occur in two types. The original "Paraplane (TM)" and it's clones have a tricycle landing gear, with seat and pusher prop suspended below a high performance rectangular parachute. Controls are very simple with foot controls for turning and a throttle to go up or down. You can learn to fly in one day! And, your hands are free for taking pictures and waving to the amazed spectators.
The second type is a foot launched version of the above. The pilot has a small backpack engine with prop mounted in a wire cage. The legs are acting as landing gear so the control lines for turning are activated with the arms just like skydivers.
Foot-launched paragliders can be launched from mountain sites like a hangglider. Or you can use the motor to gain altitude, shut it off, and make use of natural lift to stay aloft. High performance paragliders are elliptical in shape and require more training than the simple square type powered parachute. A certified training program has been approved through the U.S Hang Gliding Assn. P.O. Box 8300 Colorado Springs, Co. 80933 (719) 632-8300, (719) 632-6417
For more information on Paragliding contact:
Both types of powered parawings are slow flying (20-30 mph), and are limited to light wind and minimal turbulence. Takeoff is very short but must be DIRECTLY into the wind. The takeoff roll (or run) is begun with the chute spread out on the ground though it's possible to start with the chute in a bag for some models. The cost of these craft is not much less than other ultralights due in part to the cost of the chutes. Wear and tear can be a factor if you drag your chute trough the brambles and bounce your landings a lot. No other flying machine ever invented can pack down as small as the foot launched powered paraglider.

You may build and fly *ANY* powered aircraft which meets the (USA) ultralight vehicle definition. ANYTHING. One-man free balloons are considered unpowered ultralights (like hang gliders and other one-seat gliders) and must weigh 155 lbs. or less to qualify. An Easy Riser ultralight has flown with solar/electric power. A legal ultralight powered blimp has been built and flown. A full size rubber-band powered ultralight was demonstrated at Oshkosh '92, but did not achieve flight. It HAS lifted off, for a time, on smooth pavement,....going downhill.

Subject: Ultralight regulations in Canada
The vehicle definitions are as follows:
ULTRALIGHT SINGLE-PLACE AEROPLANE:
ULTRALIGHT TWO-PLACE AEROPLANE:
ADVANCED ULTRALIGHT AEROPLANE:
b. 480 kg (1058.2 lbs) for a two-place aeroplane.
b. 70 kg (154.4 lbs) for a two-place aeroplane.
The 'launch weight' is the total weight of the aeroplane when it is ready for flight, including any equipment, instruments, and max. fuel and oil, but not including: floats (up to 34KG/75 lbs), the occupant, and any ballistic parachute installation.
The pilot requirements are as follows:
The minimum requirement to get a Private Pilot License - Ultralight Category is 10 hours. Of which not less than 5 hours Dual and not less than 2 hours Solo time are required. Also, within these times no fewer than 30 takeoffs and landings, including no fewer than 10 as sole occupant of the aircraft must be obtained. The actual time required for the average person works out to be about 18-20 hours. "NO PASSENGERS" allowed with this license.
The only way you can legally carry a passenger would be if you held a Commercial Ultralight License. Then the passenger is supposed to be a student or a prospective student on an "Intro Ride".
With the new Advanced Ultralight category, a Private Pilot-Airplane (Certified) can carry a passenger and a Private Pilot - Ultralight can carry a passenger if the passenger also holds an Ultralight or higher License.

Subject: Ultralight magazines
ULTRALIGHT FLYING is the oldest and longest running magazine devoted to ultralights. It's a large format, newspaper tabloid size monthly publication with reviews, stories, and how-to articles. It has more commercial and classified advertisers than most of the other magazines. There are typically 80 oversize pages. Subscriptions are $30 for 12 issues or it is included with a membership in the U.S. Ultralight Assn. (which is $39.00). Write to: 1085 Bailey Avenue, Chattanooga,TN 37404. Phone (423) 629-5375. The magazine has a web page at http://www.ulflyingmag.com
EXPERIMENTER is a glossy monthly magazine of about 45 pages with
lots of color, devoted to ultralights and light planes. It is for members
of the EAA (Experimental Aircraft Assn). See Question Q203. The content
of the magazine leans more toward technical articles about the building
aspect of ultralights as might be expected from the parent organization.
The cost is $28.00 for new EAA members or $18.00 if you are already receiving
the magazine Sport Aviation.
U.S. AVIATOR, published by Jim Campbell, is a monthly publication
that covers all aspects of sport aviation including kitplanes and ultralights.

Subject: Maximum altitude for ultralights
Answer: Higher than you will probably ever want. Many ultralights can probably reach or exceed 10,000 ft. MSL. The record for a USA type FAR part103 ultralight is over 23,000 ft. The record for the higher performance microlight type is about 33,000 ft. Many ultralight pilots seldom go above even 5000 ft. It gets cold, the scenery below you is too small to make out, and it's not very exciting because the landmarks go by VERY slowly at the typical ultralight speeds. Here in the USA, numerous limits and restrictions apply to ultralights. In certain airspace such as around controlled airports, the maximum altitude is ZERO. You can't fly there at all without permission. The largest airports have an overhanging shelf of airspace which also must be avoided. Ultralights are NOT required to have a radio and transponder but, prior permission may be needed in some airspace where a transponder would otherwise be required. FAA regulations require aircraft to have supplemental oxygen at and above the 12,000 to 14,000 range to prevent hypoxia. Ultralight pilots are not immune to hypoxia. All flights which exceed 18,000 MSL require prior permission and an IFR flight plan.

Subject: Ballistic parachutes for ultralights
Ultralight and hang glider pilots have long used emergency parachutes which are attached to the aircraft instead of the pilot. You don't have to bail out. Instead the pilot and the aircraft float down together. The early "hand-deployed" designs required you to throw a 6-10 lbs package containing the chute out into the airstream and you hoped that it inflated in time. Ballistic parachutes have a mechanical device to very quickly "fire" the chute into the airstream which allows for MUCH faster deployment. Manufacturers have claimed a deployment in only 2 seconds which allows for a possible successful deployment as low as 100 ft. AGL. Some designs pack the chute very tightly inside a canister. The earliest versions used an explosive charge to fire a projectile which then pulled out the chute. Later designs have gone to a chemical rocket (no recoil). A new design uses compressed air or gas. The term "ballistic" is often loosely used to describe all types of rapid deployment schemes although the newer rocket types are not actually "ballistic". The cost of these units can be $1200-$1600. The only USA supplier is:

Subject: Hang glider trike type ultralights and microlights
A hang glider trike is a powered ultralight based on a hang glider type wing but with a tricycle geared undercarriage incorporating the pilot seating and pusher propeller and engine. The pilot controls the craft by pushing and pulling on the horizontal control bar just as in an unpowered hang glider. The term "trike" may describe just the undercarraige or it can refer to the entire unit.
The trikes are much more common outside the USA, are well suited for beginners, and are easily adapted for 2-seat training. These craft are bolt together kits, or completely assembled ready to fly. The hang glider wing is often specially designed for powered use and would likely not be also used for unpowered flight without the trike. Because the wings fold like a hang glider and the trike may also fold up partially, they are easily transported.
Regardless of you experience in other aircraft or even in hang gliders, you really MUST get some training to fly these machines. While any experience will help, you must be trained in their unique handling and takeoff characteristics or you will likely crash. :-)
Here are some sources for trikes in the USA.

Subject: Ultralight hot air balloons
Yes. Ultralight hot air balloons are quite feasible though they are
uncommon. In the USA they are considered to be unpowered ultralights
(like hang gliders) and must weight less than 155 lbs.
Several experimenters have reported excellent success with one man hot air balloons and at least on manufacturer offers kits which qualify for operation under FAR103. Write to:
Also check out the Airship and Blimp Resources Homepage found at
A powered blimp would have to be under 254 lbs to fly as an ultralight. There have been experiments, but I believe there is no operational FAR103 legal ultralight blimp at this time.
Subject: 2-axis versus 3-axis ultralights.
In simple terms, a 2-axis ultralight is one which does not have any
ailerons. Conventional fixed wing aircraft have three axis of control;
pitch (up-down), yaw (left-right), and the roll or banking function
Eliminating ailerons saves weight, cost, complexity, and simplifies
training, and breakdown for trailering. The 2-axis ultralight adds an element
of safety because they are inherently spin proof. However, in the area
of crosswind landings and flying in turbulence, the 3-axis
Some fixed wing ultralights and motorglider types have differential wing spoilers, instead of ailerons, for roll control. Though they help in turning, they do not provide the rapid response or the crosswind capability of ailerons. Such craft (e.g.the venerable Quicksilver MX) are still often functionally 2-axis airplanes.
Subject: Ultralight chat
A channel for ultralight enthusiasts has been set up on the Internet
Relay Chat (IRC) system. Almost everyone with internet access should be
able to use it but you must have IRC software for your operating system.
For MS Windows users the shareware program "mIRC" is suggested.
After installation, go to the setup and add the Q-net server at:
washington.dc.us.irc.q.net (port 6667) ......or the server at: irc.mcs.net
(port 4444) if connecting from AOL. Once you are
at 10 East, 9pm central. The Formal ultralight chat is on Monday nights. The other nights during the week are just kind of casual get togethers. For questions about AOL chat write to Flyweed@aol.com.
