The Cessna Aircraft Company is an American general aviation aircraft created in 1927 by Clyde Cessna in Wichita, Kansas, where its headquarters is currently located. The Cessna Aircraft Company is best known for small piston-powered airplanes. The Cessna 152 was first introduced in 1977 after its successor, the Cessna 150. Both the Cessna 152 and the Cessna 150 are an all-metal, high-wing two-seat aircraft with fixed tricycle landing gear widely used for flight training and for personal use. The Cessna 152 is slightly improved over the Cessna 150 with more economical operation and increased maximum certified gross weight. The Cessna 152 aims to be reliable, durable, economical and high performance for training. To meet these purposes, the Cessna 152 was designed with strong yet lightweight all metals. The aircraft fuselage is a semi-monocoque design with a conventional shaped sheet metal bulkhead, stringers and skin. The wings are externally strengthened with a 13-gallon gas tank on each side of the wing. The front and rear wing spar are constructed of shaped sheet metal ribs, doublers and stringers. Each wing was equipped with conventional hinged ailerons and single-slotted flaps that could extend from 0 degrees to 30 degrees. Each wing is balanced with each other. With the heavy engine at the front, the tail has to balance the weight forward. Therefore, the empennage and tail assembly are designed with a longer length and consist of a conventional vertical stabilizer, a rudder, a horizontal stabilizer and an elevator. For strength and durability purposes, the entire empennage control surfaces are mostly formed with sheet metal ribs and reinforcements, a wrap-around skin panel, ribs and sheet metal reinforcements. Cessna 152 designed with 8 feet 6 inches of ground clearance, 24 feet one inc...... middle of paper...... gauge to operate. The vacuum system is a motor-driven vacuum system consisting of a vacuum pump, a vacuum relief valve and a vacuum system air filter. The air passes through the air filter of the intake system which supplies it to the trim indicator, direction indicator and intake pressure gauge, mounted on the dashboard, via the vacuum pump. The directional indicator is also connected to the low vacuum warning switch, which trips the circuit breaker in the event of a vacuum system failure. Furthermore, the control surface system is also necessary to fly the aircraft. The aircraft must be able to pitch, roll or bank and yaw. To do this, each aircraft is equipped with an elevator, aileron and rudder. The elevator controls the pitch of the aircraft around the vertical axis by pushing or pulling the stick. The elevator mounted on the emmaAileron is the control of the rolling around the longitude axis.
