1. What is a symptom of carbon monoxide poisoning?

Rapid, shallow breathing.
Pain and cramping of the hands and feet.
Dizziness.

2. Which would most likely result in hyperventilation?

A stressful situation causing anxiety.
The excessive consumption of alcohol.
An extremely slow rate of breathing and insufficient oxygen.

3. What causes hypoxia?

Excessive carbon dioxide in the atmosphere.
An increase in nitrogen content of the air at high altitudes.
A decrease of oxygen partial pressure.

4. Which is a common symptom of hyperventilation?

Tingling of the hands, legs, and feet.
increased vision keenness.
Decreased breathing rate.

5. Loss of cabin pressure may result in hypoxia because as cabin altitude increases

the percentage of nitrogen in the air is increased.
the percentage of oxygen in the air is decreased.
oxygen partial pressure is decreased.

6. Hypoxia is the result of which of these conditions?

insufficient oxygen reaching the brain.
Excessive carbon dioxide in the bloodstream.
Limited oxygen reaching the heart muscles.

7. When making an approach to a narrower-than usual runway, without VASI assistance, the pilot should be aware that the approach

altitude may be higher than it appears.
altitude may be lower than it appears.
may result in leveling off too high and landing hard.

8. The illusion of being in a noseup attitude which may occur during a rapid acceleration takeoff is known as

inversion illusion.
autokinesis.
somatogravic illusion.

9. In the dark, a stationary light will appear to move when stared at for a period of time. This illusion is known as

somatogravic illusion.
ground lighting illusion.
autokinesis.

10. When making a landing over darkened or featureless terrain such as water or snow, a pilot should be aware of the possibility of illusion. The approach may appear to be too

high.
low.
shallow.

11. What is the effect of alcohol consumption on functions of the body?

Alcohol has an adverse effect, especially as altitude increases.
Small amounts of alcohol in the human system increase judgment and decision-making abilities.
Alcohol has little effect if followed by equal quantities of black coffee.

12. A pilot is more subject to spatial disorientation when

ignoring or overcoming the sensations of muscles and inner ear.
eyes are moved often in the process of crosschecking the flight instruments.
body sensations are used to interpret flight attitudes.

13. Which procedure is recommended to prevent or overcome spatial disorientation?

Reduce head and eye movement to the greatest possible extent.
Rely on the kinesthetic sense.
Rely entirely on the indications of the flight instruments.

14. What is the most effective way to use the eyes during night flight?

Look only at far away, dim lights.
Scan slowly to permit offcenter viewing.
Concentrate directly on each object for a few seconds.

15. While making prolonged constant rate turns under IFR conditions, an abrupt head movement can create the illusion of rotation on an entirely different axis. This is known as

autokinesis.
Coriolis illusion.
the leans.

16. Which observed target aircraft would be of most concern with respect to collision avoidance?

One which appears to be ahead and moving from left to right at high speed.
One which appears to be ahead and moving from right to left at slow speed.
One which appears to be ahead with no lateral or vertical movement and is increasing in size.

17. Scanning procedures for effective collision avoidance should constitute

looking outside for 15 seconds, then inside for 5 seconds, then repeat.
1 minute inside scanning, then 1 minute outside scanning, then repeat.
looking outside every 30 seconds except in radar contact when outside scanning is unnecessary.

18. When using the Earth's horizon as a reference point to determine the relative position of other aircraft, most concern would be for aircraft

above the horizon and increasing in size.
on the horizon with little relative movement.
on the horizon and increasing in size.

19. Haze can give the illusion that the aircraft is

closer to the runway than it actually is.
farther from the runway than it actually is.
the same distance from the runway as when there is no restriction to visibility.

20. Sudden penetration of fog can create the illusion of

pitching up.
pitching down.
leveling off.

21. What illusion, if any, can rain on the windscreen create?

Does not cause illusions.
Lower than actual.
Higher than actual.
