SPRATT 103

Legislation

The Spratt 103 is currently officially recognized in France as U.L.M.
“Pendular” (since 23/06/03) and “multi-axis” (since 17/04/14)
… without any limitation or prohibition.
(Which allows you to drive it according to the patent you own or wish to have!)

“Pendular” by its technique, resulting from its evolution (George Spratt is the inventor of the pendulum)

“Multiaxis” (or “gyroplane”) by its piloting with the handle on 2 axes

 

George Spratt’s pendulum in 1911


Faced with this ubuccessful situation, it is evident that the Spratt concept, due to its characteristics, must have a specific regulation

(Request made to the french DGAC since 2002)

Application for ULM Regulations Amendments

1) Creation of ULM class 7, known as “living wings”
Definition: Pendular aircraft with free wings and freestanding.
Technical conditions: idem pendular and multiaxes.
Teaching: Specific to this new class.

2) Creation of the category ULM “Part 103” in France
Base: US, UK and German ULM regulations.
Replaces the existing subclasses, called “auxiliary motorized”.

– No compulsory license (free flight regulations).
– Maximum take-off weight: single-seater = maximum 250 kg – two-seaters (for training) = maximum 350 kg
– Vmin maxi = 50 km / h
– Wing loading max. = 25 kg / m2

 

Note 1: The Spratt 103 is currently officially recognized in France as U.L.M. But … in two technically opposite categories (“pendulum” and “multiaxis” … at the choice of the pilot!;).
Faced with this inconsistency, the Spratt concept, due to its characteristics, must have a specific regulation.

Note 2: In order to correspond to the realities and needs of the ULM activity in France and following the positive example made in recent years by England and Germany (application of Part 103 US), changes in Current regulation must be made in order to rejuvenate and perpetuate this social and economic activity while avoiding that practitioners (paramotors and other light and slow machines …) having a different spirit and use of the “modern” microlights “Aircraft type.

As motorized land vehicles (automobiles and 2 wheels) circulate without a license, it is logical and necessary that a category of motorized aircraft, light and slow due to their technical characteristics, be allowed to fly without a license, Under the existing “Free Flight” regulations.

Moreover, the reference to the maximum take-off mass (250 kgs) allows the use of 4-stroke or electric engines, which are heavier but more reliable, quieter and more economical than the usual 2-stroke engines.
