  8. Most common commercial fertilizers:
    Nitrogen, Phosphorous, Potassium
  9. The acceleration experienced by the aircraft/pilot in direction perpendicular to wing is solely determined by the
    Bank Angle
  10. The flight envelope of an aircraft is
    The region of altitude and the airspeed in which it can be operated
  11. The locus of points equidistant from upper and lower surfaces of an airfoil is called the
    Mean Camber Line
  12. The straight line joining the ends of the mean camber line
    Wing Chord
  13. Two basic types of drag
    Parasitic, Induced
  14. Parasitic drag calculation
  15. Parasitic Drag
    Resistance of aircraft to the air in which it moves
  16. Induced Drag
    • Relative to wing's production of lift.
    • Low speed, high angle = induced drag
  17. Degree of movement of an aircraft around its lateral axis
  18. Delta wing aircraft have no
    horizontal stabilizer
  19. Moving the control column/joy stick to the left/right affects the ______ rather than indicating the _________

  21. An auto dealership offers a 15% discount on a used car. What's the discount on a car that is $13,620?
  22. There are ___oz in 1 lb
  23. It takes a factory 45 minutes to make 9 spindles
    How many hours will it take to make 96 spindles at the same rate?
    • 1. Find # of spindles/minute (45/9)
    • 2. 5 spindles/minute x 96 = x minutes
    • 3. x/60 = hours
  24. A guy paid 17.16 for something that had just gone up in price by 4%. What was the price before the increase?

  28. ____ maintain pich
    ____ maintain yaw
    Horizontal Stabilizer, Vertical Stabilizer
  29. Maneuver in which helicopters maintain nearly motionless flight
  30. A runway with the Approach Lighting System (ALS) would show an incoming pilot
    A series of lightbars and/or strobe lights extending outward from the runway approach end.
  31. The thrust of a turbojet is developed by compressing air in the inlet and compressor, mixing the air with fuel and burning it in the combustor, and
    Expanding the gas stream through the turbine and nozzle.
  32. A ramjet engine consists of
    An inlet, a combustion zone, and a nozzle.

    Red, White
  35. What is the difference between a steady red and a flashing red light signal from the tower to an aircraft approaching to land?
    A steady red light signals to continue circling and a flashing light signals that the airport is unsafe for landing.
