First of all, it needs to be pointed out that contemporary PPCs underwent a true evolution. Their trump is the large safety margin, low costs of the exploitation and maintenance and a small number of trainings required. The simplicity of the pilotage caused that thousands of them are in the air today. Their motto is: „low and slowly”.

The paraplane’s cart is built from air-aluminium, a very solid cage of safety. Tubings are gripped together with screws and there are pins made out of a very hard material (duromers etc) driven into the centre of tubings, but only in places of joinings. The cart has to protect a pilot and a passenger. Obviously, such a cage is equipped with a four punctual safety belts, which additionally enlarge the protection, in case of accidental revolutions. In our constructions engines of reputed firms worldwide are used: Rotax, Hirth, Symonini and HKS 4-th stroke.

Lately, the Buckeye company has began to use in its own single paraplanes „Dragonfly” four-stroke engines from generators OHV G990 -- 32 PS, as well as the Honda 24 PS engine. The use of these engines cause a smaller fuel consumption and smaller noise emission. It happens at times, that engines from automobiles and motorcycles are. However, these solutions are not used in serial constructions. Companies such as Apco, Elan, Performance Design and Chiron are leaders in the production of wings for paraplanes. There are two kinds of wings: a rectangular and elliptic one. A contemporary paraplane’s winf is made from very strong and vital materials. Gelvenor is a nylon- impregnated silicone material, as contrasted with usual fabrics from which most of the parahang-gliders are made out of. This material is really resistant to the activity of solar beams and different weather conditions.

Other materials are also being used to the production of parachutes. The construction of the wing strongly contributes to the characterization of the flight of the paraplane. As contrasted with other microflights, the small air speed characterizes it. It hesitates from 30 to 55 kms/h and is the constant during raising, straightway flights and the landing. A reason for that is the large resistance, resulting from the construction of the parachute. At this point one minus has to be pointed out – namely the aerodynamic excellence of the wing. It carries out 3-4 and 6 at elliptic wings. Otherwise, this huge flying mattress could be a reason of certain limitations, the constant speed and the very poor excellence. A second minus is the huge fuel combustion. Not as huge as in planes, but surely greater than in para hang-gliders, well-known as PPG.

Therefore the cluster of pilots of other aerodynes often wonder, how others can fly on such “a rag”? They claim it that has too many defects, the wing is dangerous, because it is soft and also many other epithets regarding paraplanes can be found in their opinion. I consider such thinking nothing more but ignorance in the aviation topic. I don’t want to abuse anyone here, but these are facts.
