The Cessna Aircraft Company is an American general aviation aircraft established in 1927 by Clyde Cessna in Wichita, Kansas, where its headquarters are currently located. The Cessna Aircraft Company is best known for its small piston aircraft. The Cessna 152 was first introduced in 1977 after its successor, the Cessna 150. Both the Cessna 152 and the Cessna 150 are all-metal, high-wing, two-seat aircraft with fixed tricycle landing gear, widely used for flight training and personal use. The Cessna 152 is slightly improved over the Cessna 150, with more economical operation and an increase in maximum certified gross weight. The Cessna 152's objectives are reliable, durable, economical and efficient for training. To satisfy this goal, the Cessna 152 was designed with all metals that are strong yet lightweight. The aircraft fuselage is a semi-monocoque design with a conventional formed sheet metal bulkhead, spar and skin. The wings are reinforced externally with a 13-gallon fuel tank on each side of the wing. The front and rear wing spars are made of formed sheet metal ribs, doublers and spars. In each wing, conventional hinged ailerons and single-slotted flaps that could extend from 0 to 30 degrees were attacked. Each wing is balanced relative to each other. With the heavy engine in the front, the tail must balance its weight forward. Therefore, the tailplane and tailplane are designed with a longer length and consist of a conventional vertical stabilizer, rudder, horizontal stabilizer and elevator. For reasons of strength and durability, all of the empennage control surfaces are mainly made up of sheet metal ribs and reinforcements, an enveloping skin panel, sheet metal ribs and stiffeners. The Cessna 152 is designed with a height of 8 feet 6 inches from the ground, a height of 24 feet. inc...... middle of paper ......indicator to use. The vacuum system is an engine-driven vacuum system consisting of a vacuum pump, a pressure relief valve and a vacuum system air filter. Air passes through the vacuum system air filter which is pumped to the dashboard-mounted trim indicator, turn signal and vacuum gauge by the vacuum pump. The direction indicator is also connected to a low vacuum warning switch, which trips the circuit breaker in the event of a vacuum system failure. Additionally, the steering system is also necessary to fly the aircraft. The aircraft must be capable of pitching, rolling or banking and yawing. To do this, each aircraft is equipped with an elevator, ailerons and rudder. The elevator controls the aircraft's pitch around the vertical axis by pushing or pulling the yoke. The elevator is mounted on the emmaAileron and controls the rolling around the longitude axis.
