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.

| 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.
