  1. INERTIA

    Newtons 1st Law
    Object at rest stays at rest unless acted upon by an outside force
  2. ACCELERATION
    The rate of change of velocity over time
  3. SPEED
    Rate of movement or motion in a given amount of time
  4. VELOCITY
    The quickness or speed of an object in a given time or direction
  5. Newtons 1st Law
    Inertia

    an object at rest will stay at rest, or an object in motion will continue in motion at the same speed and in the same direction, until acted upon by an outside force
  6. Newtons Second Law
    Force

    An object moving w/uniform speed is acted upon by an external force, the change of motion, or acceleration, will be directly proportional to the amount of force and inversely proportional to the mass of the object being moved
  7. Newtons Third Law
    Action and Reaction

    For every action there is an equal and opposite reaction
  8. Bernoulli's Principle
    The principle states that when a fluid flowing flowing through a tube reaches a constriction is increased and its pressure decreased
  9. Wind Warning
    minimize loss and damage from destructive weather
  10. Small Craft
    Winds 33 Knots or less
  11. Gale
    winds 34-47 knots
  12. Storm
    winds 48 knots or greater
  13. Tropical Cyclone warnings
    3 stages of intenstity

    • 1.tropical depression- winds 33 knots or higher
    • 2.tropical storm-winds 34-63 knots
    • 3.hurricane/typhoon-winds 64 knots or greater
  14. Thunderstorm/ Tornado Warnings
    Thunderstorm warning- within 3 miles of airfield, or in immediate area

    Severe-wind gusts 50 knots or greater and/or hail

    Tornado- tornados detected by RADAR
  15. Lift
    Force that acts in an upward direction to support aircraft in air

    Must be greater than or equal to weight if flight is to be sustained
  16. Weight
    Force of gravity acting downward on the aircraft and everything on aircraft
  17. Drag
    Force that tends to hold aircraft back

    Drag resist motion
  18. Thrust
    force developed by aircraft engine

    Must be greater than or equal to the effects of drag to fly
  19. Longitudinal axis
    imaginary referance line running down the center of the aircraft between nose and tail

    roll
  20. Lateral axis
    imaginary reference line running parallel to the wings about which pitch occurs
  21. Vertical axis
    imaginary reference line running from top to bottom of aircraft. yaw
  22. 3 primary movements of aircraft about the axis
    • pitch- up and down
    • yaw-right and left
    • roll- wing tips, one up the other down
  23. Fixed wing aircraft primary flight controls
    • ailerons control longitudinal axis
    • elevators control lateral axis
    • rudder controls vertical axis
  24. Rotary wing aircraft primary flight controls
    • collective stick controls up and down
    • cyclic stick tilits rotor blades forward aft or sideways
    • lateral control(foot pedals) controll blades on tail rotor
  25. Flap
    reduces landing speed
  26. Spolier
    use to decrease wing life
  27. Speed brakes
    hinged or moveable control surfaces used for reducing the speed of aircraft
  28. Slats (boundary layer)
    Intended primarily for use during operations from carriers; catapult takeoffs and arrested landings
  29. Horizontal stabilizer
    provides stability of the aircraft about it lateral axis
  30. Vertical stabilizer
    • directional stability
    • base to which rudder is attached
  31. Tail rotor
    counteracts the torque action of the main rotor by producing thrust in opposite direction
  32. angle of attack
    angle at which a body, such as an airfoil or fuselage, meets a flow of air
  33. autorotation
    method used allowing a helicopter to land saftley from altitude w/out using engine power, useing reverse airflow through rotor system to reduce rate of decent
  34. Components of basic hydraulic system
    • reservoir- holds fluid
    • pump- flow
    • tubing- transmits fluid
    • selector valve- direct flow
    • actuating unit-convert fluid presure
