Name: ___________________________________________

1. When an aircraft ___________________, turns, or changes ______________________, it experiences G forces—changes in apparent __________________________.
2. Rapid ______________________________ and steeply banked, _________________________ turns create positive Gs—forces acting in the direction of the pilot's ________________________. They displace _________________________ and the body's organs toward the lower _________________________. As the ________________________ circulation to the _____________________ decreases under positive Gs, the pilot's ________________________ field narrows. If positive Gs increase, the pilot loses _______________________ vision and eventually loses _____________________________.
3. Rapid _____________________________ and "outside" aerobatic maneuvers create ___________________________ Gs—forces acting toward the pilot's ______________________.
4. Motion sickness is caused by continued ____________________________ of the tiny portion of the ____________________________ ear that controls the sense of ___________________________. __________________________, abrupt maneuvering, ____________________________ temperatures, ________________________, and lack of outside _______________________________ references can contribute to or exacerbate motion sickness.
5. If you are susceptible to airsickness, ________________ ___________________ take the preventive drugs that are available over the counter or by prescription (unless, of course, you are a passenger). These medications may make you _____________________________ or depress your _________________________ functions in other ways.
6. If you suffer from airsickness, _________________________ the air vents, __________________________ your clothing, use ______________________________, keep your eyes on a point outside the airplane, hold your head still, and avoid ____________________________ maneuvers. Then _________________________________ as soon as possible. And always keep a supply of ___________________________ bags close at hand.
7. ___________________________________, also known as "spatial disorientation," is a state of temporary confusion resulting from misleading information sent to the ____________________________ by various sensory organs.
8. Spatial disorientation occurs most often in __________________________________ meteorological conditions created by ______________________, ______________________, _____________________, smoke, or _____________________________ nights. It is aggravated by lack of recent instrument experience or training, unfamiliarity with the aircraft or flight situation, ____________________ or worry, and excessive ___________________________ movements.
9. Describe three day time, and three night time visual illusions:
   1. _________________________________________________________________________
      _________________________________________________________________________
   2. _________________________________________________________________________
      _________________________________________________________________________
   3. _________________________________________________________________________
      _________________________________________________________________________
   4. _________________________________________________________________________
      _________________________________________________________________________
   5. _________________________________________________________________________
      _________________________________________________________________________
   6. _________________________________________________________________________
      _________________________________________________________________________
10. Describe the proper technique for scanning for aircraft:
    _________________________________________________________________________
    _________________________________________________________________________
    _________________________________________________________________________
    _________________________________________________________________________
11. Hypoxia—_________________ of ________________________—is the greatest single danger to a pilot at _______________________________ altitudes. When a pilot ______________________ air at _______________________________ altitudes, there isn't enough oxygen _______________________ to force adequate amounts of this vital gas through the ______________________________ of the ________________________________ into the bloodstream...
12. List four symptoms of hypoxia
    1. _________________________________________________________________________
    2. _________________________________________________________________________
    3. _________________________________________________________________________
    4. _________________________________________________________________________
13. The FARs (FAR 91.211) and CAR's require pilots to use supplemental oxygen when flying at high altitudes. Whenever an unpressurized airplane is operated between _____________________ and _________________________ ft for more than _____________ minutes the crew must use ____________________________ oxygen.
14. List fours ways to avoid hypoxia:
    1. _________________________________________________________________________
    2. _________________________________________________________________________
    3. _________________________________________________________________________
    4. _________________________________________________________________________
15. The consumption of _______________________ drug, including ________________________, can ___________________________ your ability to fly an airplane, and with few exceptions the use of drugs is ____________________________ by the FARs and CARs. Before using any drug—even an _______________-the-____________________ medicine—review its side effects with your ___________________ _______________________ ________________________ (AME). Pilots remember these rules with the rhyme "___________________ hours from ___________________ to __________________________.
