Development
To meet a Regia Marina requirement for a two-seat catapult-launched seaplane, Piaggio produced two designs. The first designated the P.6bis was a small biplane flying boat powered by a 190 kW (260 hp) Isotta Fraschini V.6 engine driving a pusher propeller. The second design designated, the P.6, was a floatplane with one large central float and two stabilising floats at the wingtips and a nose mounted A.20 engine. Both aircraft had the same biplane wing structure with rigid strut bracing and both were armed with a single machine gun (the flying-boat's in the bow and the floatplane's in the rear cockpit). In 1928, the P.6ter was produced based on the P.6 floatplane with the engine boosted to 306 kW (410 hp). A production run of 15 P-6ter aircraft was produced for the Italian Navy where it had an unremarkable career being used on battleships and cruisers.

Famous quotes containing the word development:
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .”
—Selma H. Fraiberg (20th century)
