ASTB Aviation Information. Top Questions with accurate answers, rated A+ What is the landing gear in the rear of the airplane called? - ✔✔conventional landing gear What is the landing gear u... nder the nose of the plane called? - ✔✔tricycle landing gear 2 types of fixed wing aircraft propulsion systems are? - ✔✔propellers and jets Describe fixed pitch propeller - ✔✔can't be adjusted by the pilot and is attached to the motor Discribe variable pitch propeller - ✔✔more efficient than fixed can. be adjusted by the pilot for the most efficient operation Tail assembly aka - ✔✔Empennage Tail elevators - ✔✔Controls the nose of the airplane Rudder - ✔✔attached to the tails verticle stabilizer. Moves the planes nose left and right during flight. Y axis Purpose of trim tabs - ✔✔reduce control pressures and decrease the pilot's workload. Newtons First Law of Motion - ✔✔inertia- an object at rest or in motion must stay at rest or in motion unless acted upon by an outside force. Newtons Second Law of Motion - ✔✔Force=Mass Acceleration F= ma Bigger the mass the more Force is needed to accelerate. Newtons Third Law of Motion - ✔✔For every action, there is an equal and opposite reaction. (Jets propulse heat out pushing the plane forward) 4 forces acted upon an aircraft during flight - ✔✔gravity, lift, thrust, and drag. List pushes up, gravity pulls down, thrust pushes forward, drag pulls backward. Bernoulli's Principle - ✔✔Hydrodynamics- Airfoil; The faster a fluid (air) travels, the less time it has to exert pressure over any given part of that surface. What cause lift? - ✔✔The difference of air pressure above and below the wing. Amount of camber of a wing creates more or less lift. What is a stall caused by - ✔✔the seperation of airflow from the wing's upper surface, resulting in a rapid decrease in lift. Avoiding stalls - ✔✔Change angle of attack. Define weight - ✔✔the force produced by mass of the airplane interacting with earth's gravitational field. Must be counteracted by lift to create flight. Profile or parasitic drag - ✔✔experienced by all objects in an airflow. Caused by an airplane pushing air out of the way as it moves forward. longitudinal axis - ✔✔axis that runs lengthwise from the nose to the tail of the airplane. Causes rolling lateral axis - ✔✔wing tip to wing tip. Causes pitching vertical axis - ✔✔the axis that runs from bottom of the airplane to the top. causes yawing. Turning left and right (twister game) Sea level weight of air - ✔✔14.7lbs per inch aka 1 ATP Warmer air is less dense than cooler air producing - ✔✔less lift. Cooler the air causes greater lift. Primary system controls - ✔✔ailerons, rudder, elevator/stabilator Secondary system controls - ✔✔... Two types of flight control systems are - ✔✔Primary and Secondary Controls Joy stick controls - ✔✔roll (movement around the longitudinal axis) and pitch (movement around the lateral axis) Rudder pedals control - ✔✔yaw; movement of nose left/right in a horizontal sense. Moving the joystick to the right causes the right aileron to - ✔✔deflect up and left to deflect downward. Upward deflection causes a decrease in camber pulling the wing tip down. Downward deflection does the opposite causing the wingtip to rise. Stabilator - ✔✔one surface of the horizontal stabilizer that causes lift. (most planes have two separate elevators) Four secondary control devices are - ✔✔Flaps, leading edge devices, spoilers, and trim systems. Spoilers do what? - ✔✔increase drag and decrease lift. Some spoilers are used for roll control. One advantage is the elimination of adverse yaw. Deploying both spoilers allows the aircraft to descend without gaining speed. By destroying lift during landings, they increase braking and transfer weight to the wheels. Trim systems do what? - ✔✔relieve the pilot from the need of constant pressure to the control systems. Altimeter - ✔✔gives the pilot altitude readings. Short hand is for 10000's intermediate is for 1000's and Long is for 100s. Denser air produces more or less lift? - ✔✔More Oxygen is used in flights above 10000 feet in order to - ✔✔ [Show More]
