FOA Lesson 9: Physiological Factors

Which would most likely result in hyperventilation?

• Emotional tension, anxiety, or fear.

• The excessive consumption of alcohol.

• An extremely slow rate of breathing and insufficient oxygen.

Rapid or extra deep breathing while using oxygen can cause a condition known as

• aerotitis.

• aerosinusitis.

• hyperventilation.

Which technique should a remote pilot use to scan for traffic? A remote pilot should

• systematically focus on different segments of the sky for short intervals.

• concentrate on relative movement detected in the peripheral vision area.

• continuously scan the sky from right to left.

When a stressful situation is encountered in flight, an abnormal increase in the volume of air breathed in and out can cause a condition known as

• hyperventilation.

• aerotitis.

• aerosinusitis.

The most effective method of scanning for other aircraft for collision avoidance during daylight hours is to use

• a series of short, regularly spaced eye movements to search each 10-degree sector.

• peripheral vision by scanning small sectors and utilizing off-center viewing.

• regularly spaced concentration on the 3-, 9-, and 12-o'clock positions.

You are a remote pilot for a co-op energy service provider. You are to use your UA to inspect power lines in a remote area 10 hours away from your home office. After the drive, fatigue impacts your abilities to complete your assignment on time. Fatigue can be recognized

• as being in an impaired state.

• by an ability to overcome sleep deprivation.

• easily by an experienced pilot.

Which is true regarding the presence of alcohol within the human body?

• Consuming an equal amount of water will increase the destruction of alcohol and alleviate a hangover.

• Judgment and decision-making abilities can be adversely affected by even small amounts of alcohol.

• A small amount of alcohol increases vision acuity.

A pilot experiencing the effects of hyperventilation should be able to restore the proper carbon dioxide level in the body by

• increasing the breathing rate in order to increase lung ventilation.

• breathing spontaneously and deeply or gaining mental control of the situation.

• slowing the breathing rate, breathing into a paper bag, or talking aloud.

Why is fatigue hazardous to flight safety?

• Fatigue may not be apparent to a pilot until serious errors are made (an impaired pilot is a dangerous pilot).

• The pilot hurries to get done in order to rest.

• The pilot is lazy and rushes to get done quickly.

A pilot should be able to overcome the symptoms or avoid future occurrences of hyperventilation by

• slowing the breathing rate, breathing into a bag, or talking aloud.

• closely monitoring the flight instruments to control the airplane.

• increasing the breathing rate in order to increase lung ventilation.
