Regular readers will know about my interest in cheap (or rather, ‘less expensive’ – nothing in aviation is cheap) single seat ultralight aircraft.

One of my favourites, the Aerolite 103 (Aerolite 120 in Europe) is now available with a 4-stroke Briggs & Stratton 22 hp engine. Although heavier and a bit less powerful than the 2-stroke alternatives, the B&S motor still gives the aircraft a climb rate around 600 fpm and a cruise speed in the same 60 mph range. And of course it does it more quietly, using less fuel and, dare I say it, more reliably.

These very light 1-seat ‘Part 103’ aircraft have been slow to catch on, even in the USA, where you can fly them legally without registration or even a pilot’s license. This, in spite of the low purchase and running costs and (optional) folding wing, which allows storage in a garage or in the corner of a hangar which can’t be used by conventional fixed-wing aircraft. However, Aerolite reports growing sales in USA – more than 40 in 2014 – and now there is a German type-certified version – the Aerolite 120 – it looks like sales are set to grow exponentially over the next few years.

Priced from under US$15,000 (factory built!) for a 2-stroke version and probably under US$16,000 for a 4-stroke version, the Aerolite represents a great starting point for impecunious aspiring young pilots.

Factory-built single seat aircraft which are accepted under FAA Part 103 still cannot be registered in Australia, you have to build from a kit to be legal. In spite of lobbying from several sources, CASA and RA-Aus have still not woken up to the potential of these low cost aircraft as entry points for the more expensive end of the market. I wonder when RA-Aus will stop moaning about declining membership numbers and do what they should be doing to open aviation at grass roots level and work with CASA to ‘de-regulate’ these single seat aircraft? USA has done it. UK has done it. The rest of Europe has, in its own way, done it. Australia is now well behind in this growing ultralight market – what a shame.

    • The pilot manual does not appear to specify minimum and maximum pilot weights. However…the empty weight of the aircraft is around 315 pounds (about 145 kgs) and the maximum gross weight is 600 pounds (about 273 kgs). Therefore there is about 285 pounds (about 130 kgs) left for fuel and pilot. Full fuel weighs about 60 pounds (27 kgs), so that means the maximum pilot weight, with full fuel on board is about 225 pounds (102 kgs). These are only guide figures – the actual empty weight of the aircraft will vary depending on options fitted etc. You can find all the available information on the plane at: https://www.uflyit.com/aerolite103main.htm
