For a pilot to get through most

organizations' full pilot syllabus requires between 5 and 15 days which, due to

weather, may include far more calendar time. A number of techniques are

employed for teaching, although most include getting the student familiar with

handling the wing either on the ground, via towing, small hills, or on tandem

flights.

With special gear it is possible to take a

passenger (tandem), but most countries, including the U.S., require some form

of certification to do so.

The term was first used by Englishman Mike

Byrne in 1980[1] and popularized in France around 1986 when La Mouette began

adapting power to the then-new paraglider wings.

Power plants are almost exclusively small

two-stroke internal combustion engines, between 80 cc and 350 cc, that burn a

mixture of gasoline and oil. These engines are favored for their quick high

r.p.m. thrust and low weight, using approximately 3.7 litres (1 US Gal.) of

fuel per hour depending on paraglider efficiency, the weight of unit plus

pilot, and flying weather conditions. At least one manufacturer is producing a

4-stroke model favored for its strong lower r.p.m. thrust and better fuel

efficiency. Electrically powered units also exist, though flight duration is

considerably limited on the battery's electrical capacity. Csaba Lemak created

the first electric PPG, flying it first on 13 June 2006.[2][3] Wankel rotary

engined paramotors are also available, but rare.

Paramotor is the generic name for the

harness and propulsive portion of a powered paraglider ("PPG"). There

are two basic types of paramotors: foot launch and wheel launch.

Foot launch models consist of a frame with

harness, fuel tank, engine, and propeller. A hoop with protective netting

primarily keeps lines out of the propeller. The unit is worn like a large

backpack to which a Paraglider is attached through carabiners.

Wheel launch units either come as complete

units with their own motor, or as an add-on to a foot launch paramotor. They

usually have 3 (trike) or 4 (quad) wheels, with seats for one or two occupants.

These should not be confused with Powered Parachutes which are generally much

heavier, more powerful, and have different steering.

In many countries, including the United

States, powered paragliding is minimally regulated and requires no licence. The

ability to fly both low and slow safely, the 'open' feel, the minimal equipment

and maintenance costs, and the portability are claimed to be this type of

flying's greatest merits.[1]

Powered paragliders usually fly between 15

to 50 mph (24 to 80 km/h) at altitudes from 'foot-dragging on the water' up

about to 18,000 ft (5,500 m) or more with certain permission although most

flying is done under 500 ft (150 m) AGL.[2] Due to the paramotor's slow forward

speed and nature of a soft wing, it is not safe in high winds, turbulence, or

intense thermal activity.

The larger the pilot, the larger the size

of the wing and thrust required to launch. Most individuals in reasonably good

health can foot-launch a paramotor and there are even pilots with artificial

joints foot launching. Individuals that may have issues with the physical

aspect of foot launching may opt to add a trike or quad to their paramotor. A

trike or quad is a platform to which the paramotor can be attached so it can be

launched from wheels like a regular aircraft or powered parachute.

A powered paraglider trike landing

Lightweight carts or "trikes"

(called "quads" if they have four wheels) can also be mounted on powered

paragliders for those who prefer not to, or are unable to, foot launch. Some

are permanent units.

In the United States, if the aircraft meets

the ultralight definitions, no license is required. In the UK, trike-mounted

paramotors are still classified as 'self-propelled hang-gliders' if the

"performance of the aircraft remains equivalent to one that can be

foot-launched." [7]. However, even in these countries, if the machine has

two seats it is no longer an ultralight. In the US such a craft would be governed

under the Sport Pilot rules and regulated as a light sport aircraft powered

parachute which requires an aircraft N-number and pilots must be licensed.
