Ultralights - the new
revolution

the Australian Jabiru
For decades, the design of certified light
aircraft remained somewhere around the World War Two era; sheets of aluminium
riveted onto aluminium structure and drag which would do a holly bush
justice. The problem has been with the way new aircraft are certified, which
is a long and terribly expensive process which has discouraged new ideas for
a whole generation. In order to qualify for certification the requirements
were so exacting that it was virtually impossible to design a modern
aircraft.
The revolution in kit built aircraft and
advances in carbon fibre technology has changed all that. The requirements
are much more lenient with experimental aircraft allowing huge advances in
technology and performance albeit with a slight increase in demand for pilot
skill. It must not be forgotten that in the event (heaven forbid) of a crash,
aluminium will crumple all around you while composite structures are far
better in accidents. One only has to look at the horrific crashes of modern
race cars to see this. Most times, these days, the drivers just walk away
from the crash.

The European weight restriction of 450 Kilos for
VLAs (ULMs) has allowed a whole new and exciting range of real high
performance aircraft that make many certified two seat aircraft look a bit
silly and definitely not at all 'sexy'.

The weight restrictions have of course affected
the levels of interior trim and equipment, which for the most part are rather
basic. Fuel range can be a bit compromised when flying to up and baggage has
to be kept to a very minimum but this is a small price to pay for a new
series of aircraft which are very economical to run and maintain which need a
more simple form of medical examination and training. Some aircraft appear to
be a bit flimsy but extensive use in flight training establishments has shown
that they generally stand up very well.
It is almost certain that within a few years, most private pilots will
following this path and many two seat certified aircraft will be consigned to
museums!
