Term
 What is motion?
Definition
 the basic fundamentals of aviation
Term
 Acceleration
Definition
 Rate of change of speed
Term
 Speed
Definition
 Rate of movement
Term
 Velocity
Definition
 Speed of object
Term
 Newton's First Law of Motion
Definition
 (inertia)object at rest will stay at rest. object in motion will remain in motion unless acted upon a force
Term
 Newton's Second Law of Motion
Definition
 (force)object moving at uniform speed is acted upon by an external force, change of motion, or acceleration, will be directly proportional to the amount of force, inversely proportional to the mass of object.(or force is equal to the change in momentum)
Term
 Newton's Third Law of Motion
Definition
 (action and reaction)for every action, there is an equal and opposite reaction
Term
 Bernouli's Principle
Definition
 fluid flowing through a tube reaches a constriction of the tube, speed of fluid passing through construction is increased, pressure is decreased
Term
 Lift
Definition
 force in an upward direction
Term
 Weight
Definition
 force of gravity acting downward
Term
 Drag
Definition
 force holding aircraft back
Term
 Thrust
Definition
 force pushing aircraft foward
Term
 Longitudinal Axis
Definition
 imaginary reference line running down center of jet between nose and tail
Term
 Lateral Axis
Definition
 imaginary reference line running parallel to the wings
Term
 Vertical Axis
Definition
 imaginary reference line running from top to bottom of jet
Term
 Ailerons
Definition
 (roll)or longitudinal axis
Term
 Elevators
Definition
 (pitch)lateral axis
Term
 Rudders
Definition
 (yaw)vertical axis
Term
 Cyclic Stick
Definition
 (roll/pitch)tilts the plane (angle) of the rotor blades forward, aft or sideways.
Term
 Tail Rotor (yaw)
Definition
 counteracts torque of the main rotor by increasing or decreasing the amount of horizontal thrust
Term
Definition
 creates extra lift
Term
 Spoiler
Definition
 decrease or spoil wing lift by destroying the smooth flow of air. creates more predictable landing glideslope
Term
 Speed Brakes
Definition
 hinged or movable control surfaces reducing speed of aircraft
Term
 Slats
Definition
 movable control surface attacked to leading edge of wing. allows aircraft to be controlled at airspeeds below the normal landing speed
Term
 Collective
Definition
 lift is accomplished by rotating the blades through the air at a high speed. lift can be changed collectively increasing angle of attack or pitch of rotor blades.
Term
 Angle of Attack (AOA)
Definition
 angle which the airfoil or fuselage meets a flow of air measured in units
Term
 Autorotation
Definition
 method of allowing the helicopter to land safely without using engine power.
Term
 Basic aircraft hydraulic system
Definition
 reservoir to hold hydraulic fluidpump to provide flow of fluidtubing to transmit fluidselector valve to direct flow of fluidactuator unit to convert fluid pressure to work
Term
 Shock Strut Assembly
Definition
 absorbs shock
Term
 Tires
Definition
 allows aircraft to roll easily and provides traction during takeoff and landing
Term
 Wheel Brake Assembly
Definition
 provides brakes for the aircraftused to slow and stop aircraft
Term
 Retracting and Extending Mechanism
Definition
 necessary hardware to electrically and hydraulically retract and extend landing gear
Term
 Side Struts and Supports
Definition
 provides later strength/support for landing gear
