Prue Standard

Design and development

The Prue Standard was designed in response to the Fédération Aéronautique Internationale introduction of rules creating the Standard Class. The prototype was completed in 1961.
The Standard is an all-metal aircraft with a fixed monowheel landing gear. The prototype originally had wings with a span and dive brakes on the lower wing surface. The wing employs a NACA 63-618 laminar flow airfoil, an I-beam spar and has a semi-tapered planform.
Only three examples were completed, all were different and all have since been modified further. The type was further refined into a new design in 1962, the Prue Super Standard.
