gg Micro-light flying has recently developed more rapidly than any other form of recreational flying and it is gradually beginning to replace more conventional flying activities.

 

g    
Micro-lights consist of a mixture of tubes and canvas, powered by a two-stroke engine but, in practice, you will be surprised by their impeccable aerodynamic performance, the reliability and quality of their modern motors, and particularly by their comfort and safety.These machines come in the form of trikes, delta wings or three-axis models (which are similar to planes in shape). They have very good cross-country performance and excellent manoeuvrability, with only short take-off and landing requirements. The difference between flying a conventional light aircraft and a micro-light can be compared to the difference between driving a car and a scooter.

A little bit of history:

The micro-light is a relatively recent development. It all started with the development of the delta shaped wing. After the first flying machines were built at the beginning of the 20th century, an American, Francis Rogallo invented the delta shaped wing around 1936. Somewhat later

at the end of the sixties, some sportsmen, such as the French water-skier, Bernard Danis started to use a delta wing. But the first delta-wing plane was not built until 1972, followed by a motorised version in 1973, the so-called French 'cricket' which was powered by a chain-saw motor. The next step in development for these innovative machines, was a pendular (or trike) model such as Jean-Marc Geiser's Motodelta which had its maiden flight in 1975. Gradually other machines evolved along the same principles. There was a huge growth in interest in micro-light flying during the 1980s, with thousands of new enthusiasts. Numerous clubs were set up to meet the substantial increase in demand. Modern micro-lights, ie the three-axis Class 3 models, look more and more like small aeroplanes. This recent trend is counter to the original concept of non-motorised flight but is better suited to people who prefer the comfort of a small plane, while still enjoying the sense of adventure associated with micro-lights.

Some technical information:

We may often feel that these strange micro-light machines which appear unexpectedly overhead are rather like unwelcome guests and we may sometimes make rather scathing comments about them. This new phenomenon has arisen as a result of our present-day interest in leisure and outdoor activities, as well as government policies which tend to favour 'deregulation'. Micro-lights are the first flying machines to benefit enormously from the government's liberal attitude. From now on micro-lights will be made from air industry standard materials.

Classic micro-lights (Class 1 and 2) are made predominantly from assembled aluminium alloy tubing.The rigidity of the structure is then ensured by encasing it in canvas which has been cut and sewn into the correct shape before being stretched over the framework. Synthetic or composite materials (carbon fibres) are most commonly used on high performance machines.

Class 1

Paramotors. A micro-light paramotor is an aerostat which is kept aloft by a paraglider-style soft canopy.

Class 2

Trikes: These are piloted by displacing the centre of gravity. This type of micro-light remains true to its origins, in that it is piloted in the same way as the original delta-wings by using a trapeze. The maximum weight that can be carried by a one-person trike is 300 kg or less and by a two-person trike is 450 kg. These weights can be increased by 5% if the micro-light has an emergency parachute or floats, stalling speed is 65 km per hour or less and the maximum all-up weight is less than 30 kg per square metre.

Class 3

Three-axis models: Manoeuvring this type of micro-light is similar to piloting an aeroplane. It can be manoeuvred along two axes (yaw and pitch) or three axes (yaw, pitch and roll) through aerodynamic control surfaces. Maximum weight is 300 kg or less for single-seaters and 450 kg for two-seaters. These weights can be increased by 5% if the micro-light has an emergency parachute or floats, stalling speed is 65 km per hour or less and the maximum all-up weight is less than 30 kg per square metre.

Class 4

Autogyros: These have evolved from helicopters and function by using revolving blades but they are powered by micro-light type motors.

Class 5

Aerostats: This class is still at an experimental stage. These are lightweight helium or hot-air aerostats powered by an engine. Both the size of the balloon and the size of motor are subject to regulations.
