The Cessna 150 is a two-seat tricycle gear general aviation airplane that was designed for flight training, touring and personal use. The Cessna 150 is simple, robust, and easy to fly. For these reasons, it has become one of the world's most popular basic trainers.
Cockpit visibility is generally good other than directly above the aircraft, where the view is blocked by the wing. This obstruction is of particular concern when, as is the case with most high-wing aircraft, the inside-turn wing blocks vision in the direction of a turn. As a partial remedy to this some 150s, including all Aerobats, feature a pair of overhead skylights.
Power-on and power-off stalls are easily controlled. Normal spin recovery techniques are highly effective.
The Piper PA-28 Cherokee is a family of light aircraft built by Piper Aircraft and designed for flight training, air taxi, and personal use. The PA-28 family of aircraft are all-metal, unpressurized, single-engine, piston-powered airplanes with low-mounted wings and tricycle landing gear. They have a single door on the copilot side, which is entered by stepping on the wing.
The Piper PA23-250 Aztec, is a four-to-six-seat twin-engined light aircraft aimed at the general aviation market. The United States Navy and military forces in other countries also used it in small numbers. Originally designed in the 1950s by the Stinson Aircraft Company, Piper Aircraft manufactured the Apache and a more powerful version, the Aztec, in the United States from the 1950s to the 1980s.
Later Aztecs were equipped with IO-540 fuel-injected engines and six-seat capacity, and remained in production until 1982. There were also turbocharged versions of the later models, which could fly at higher altitude.
The United States Navy acquired 20 Aztecs, designating them UO-1, which changed to U-11A when unified designations were adopted in 1962.
