Grumman American AA-5 - Development

Development

Following American Aviation's success with the AA-1 Yankee Clipper two place light aircraft in 1969, the company decided to produce a four-seat aircraft. They started with a new "clean-sheet" design that was designated the American Aviation AA-2 Patriot. The AA-2 design did not meet its performance goals during test-flying and only one was ever built.

Still needing a four-seat aircraft to fill its product line, the company simply enlarged the external and cabin dimensions of the AA-1 Yankee to create the four-seater. This decision capitalized on the marketplace identification of the Yankee and its derivative the AA-1A Trainer and also resulted in 2/3 parts commonality between the designs, saving development time and production costs.

Famous quotes containing the word development:

    For decades child development experts have erroneously directed parents to sing with one voice, a unison chorus of values, politics, disciplinary and loving styles. But duets have greater harmonic possibilities and are more interesting to listen to, so long as cacophony or dissonance remains at acceptable levels.
    Kyle D. Pruett (20th century)

    This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.
    Henry David Thoreau (1817–1862)

    There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.
    John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
