A microlight is defined in the UK as "An
aeroplane having a maximum total weight authorized not exceeding 390 kg, a wing
loading at the maximum total weight authorized not exceeding 25 kg/sq.m., a
maximum fuel capacity not exceeding 50 litres and which has been designed to
carry not more than two persons". (Article 106 of the Air Navigation
Order 1989).
In practice this results in a simple, light
weight machine which takes off and lands in a very short space (sometimes less
than 50 m) is cheap and easy to maintain and fly, and is enormous fun.
There are several basic types of microlight:
- Trikes, which are controlled by 'weightshift'
in a similar way to a hang glider.
- Three Axis which have controls akin to
conventional aircraft.
- Powered Parachutes which may be either the
sort which has wheels or alternatively a lightweight kind which are foot
launched. The latter are often referred to as 'Paramotors'.
The performance of both of the first two types
is similar; a typical cruise will be around 50 - 65 mph. Each type has their
particular merits.
Powered Parachutes tend to be limited to use
in favorable weather conditions but are extremely easy to fly and often very
compact.
Microlights are normally powered by simple two
stroke engines, providing high power at low weight and cost. To fly in UK, the
aircraft design must comply with airworthiness standards set by the CAA.
The UK standards are the most stringent in the
world. The aircraft must also comply with strict noise requirements, set by the
DoT and tested by the CAA. Microlights are the lowest cost, powered aircraft
available. While a new, top of the market machine may cost £20,000, there are
many fully airworthy, certificated secondhand machines available for less than
£2,500. A secondhand single seater can cost less than £1800. An alternative to
buying a new or used factory built machine is to build a kit or even your own
design. Low costs do not only apply to purchase prices either: microlights can
be easily derigged and packed up to be carried on a lightweight trailer for
storage at home.
In spite of their low weight and cost,
microlights are extremely capable aircraft. As well as being excellent fun for
local flying, in competition standard machines frequently fly 1000 kms a day,
stay aloft for 8 hours without refueling, and land in 50 m. In September 1995,
3 microlights were flown from Madrid to London in one day and two and a half
hours. Many members fly over the channel and tour the continent with their
machines Flights have also been made from London to Cape Town, India and
Australia.
