Safety and regulations

Research estimates that the activity is

slightly safer (per event) than riding motorcycles and more dangerous than

riding in cars.[3] The most likely cause of serious injury is body contact with

a spinning propeller. The next most likely cause of injury is flying into

something other than the landing zone.[4] Some pilots carry a reserve parachute

designed to open in as little as 50 ft (15 m).

The lack of established design criteria for

these aircraft led the British Air Accidents Investigation Branch to conclude

in 2007 that "Only when precise reserve factors have been established for

individual harness/wing combinations carrying realistic suspended masses, at

load factors appropriate to the maneuvers to be carried out, can these aircraft

be considered to be structurally safe"[5]

The pilot controls thrust via a hand-held

throttle and steers using the wings brake toggles or stabilo steering, weight

shifting or a combination of the three. It is identical to Paragliding except

it is powered so the use of an elevation or thermals to ascend are not

required. Paramotor wings have evolved specifically for use with power

propulsion, as compared with free flight 'paraglider' wings. Such wings are

typically designed for a higher speed and may incorporate a "reflex"

profile to aid stability in pitch, an idea taken from hang gliders of the

1980s. Paramotor wings typically use trimmers to adjust the Angle of Attack of

the wing to either slow it down or speed it up in flight. Trimmed out allows

the pilot to achieve maximum speed, while trimmed in allows for slower speeds

optimized for launching and landing.

Noise

Paramotor noise relative to an observer

depends on distance, loudness, frequency and timbre of the power unit. Most

noise comes from the propeller and slow rpm is perceived as the quietest.

Pilots mitigate their sound impact by leaving a noise-sensitive area at low

power, keeping the farthest practical distance away, and reducing time spent

near the area.

License and training

Neither a license nor specific training is

required in the U.S., U.K. or many other countries. Where there is no specific

regulation (e.g. Mexico), paramotor flying is tolerated provided the pilots

cooperate with local officials when appropriate.[citation needed] In countries

where specific regulation exists, such as Canada, France, Italy, and South

Africa, pilots must be trained, both in flying theory and practice, by licensed

instructors. Some countries that require formal certification frequently do so

through non-government ultralight aviation organizations.

Regardless of regulations, powered

paragliding can be dangerous when practiced without proper training.

The paramotor, weighing from 45 to 90 lb

(20 to 41 kg) is supported by the pilot during takeoff. After a brief run

(typically 10 ft (3.0 m)) the wing lifts the motor and its harnessed pilot off

the ground. After takeoff, the pilot gets into the seat and sits suspended

beneath the inflated paraglider wing like a pendulum. Control is available

using brake toggles for roll and a hand-held throttle for pitch.

Military

Powered paragliding has seen a large growth

in the military including insertion of special forces soldiers and also Border

Patrol in many governments. The Lebanese Airborne regiment adopted this

technique in 2008, and the US Army, and Egyptian Army have used Paramotor Inc

FX Series units for many years.

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.
