History of Very Light Aircraft starts in the late ’70 years of the past century. VLA legalization begins in the early 80’s, after governments developed and apply additional regulations. After VLA aircrafts have become accessible to a wider audience, the new sport and fun in flying have been developed.
Experience and needs expansion purposes are conditioned to be in ‘90 with the radical corrected regulations. Since the technical and legal issues become far more serious than they were in the beginning, they took to the exclusive jurisdiction and supervision of state authorities for civil aviation.
VLA, as a specific category of aircraft, is very heterogeneous. The limits of mutual differences are apart, from professional to amateur commercial airplanes for fun and hobby. Accordingly different concepts, structures applied different technology and solutions.
Principles of optimization and choice of materials in the construction of structures are transferred from the aviation experience and knowledge. A very light aircraft is relatively low airspeed, low mass, and consequently the total loads are small and principles of the present use of light construction structure. In addition to the structure of aluminum alloys and composites, the most common is the use of mixed construction of the carrier tube and a stretched canvas. The tubes are made of composites or aluminum alloy.
The drive is usually the piston engine and propeller, whose installation is usually behind the cab (push principle) or over the wing. In this way the pilot gets full (panoramic) visibility in front of the aircraft. The most used internal combustion engines, and lately are quite present and electric motors with batteries or solar energy. Internal combustion engine have the strength, the approximate level of small and medium-sized cars, consumption per kilometer of distance traveled are similar.
