The Boulton Paul P.106 was a design for an elementary training aircraft, but that lost out to the Percival Prentice.
The P.106 was designed in response to Specification T.23/43, which called for a replacement for the Tiger Moth and Magister. The new aircraft was to be a three-seater, with the normal instructor and pupil sitting side by side in the front, but with a third seat behind.
The P.106 was a low winged monoplane, with braces for the wing and a fixed undercarriage. It was to be powered by a Gipsy III or Gipsy Queen II engine.
Three versions of the P.106 were outlined. The P.106A would have had two side-by-side seats. The P.106B had the three seat layout required by the specification. The P.106C had a tandem two-seat layout, with a narrow fuselage, and the instructor in a raised rear seat.
The crew sat under a large glazed canopy with a flat front and sides.
The P.106B was expected to be the slowest of the three layouts, with a top speed of 141mph with the Gipsy II or 145mph with the Gipsy III engine. The P.106A would have been 1.5mph faster, followed by the P.106C, which would have been 3.5mph faster than the P.106A. Climb rates altered in a similar way, ranging from 195ft/ min to 220 ft/,on.
The P.106 lost out to a Percival design, which entered service in 1947 as the Percival Prentice.
