1.2 Physiology of Flight

Training Objective:

The crew member will be able to identify and describe the most common physiological effects of flight in pressurized aircraft including likely causes, recognition and ways to minimize these effects.


Effects of Altitude

1.2A General

1.2A.1 Identify the body's requirement for oxygen and the potential for crew member incapacitation due to lack of oxygen.

1.2A.2 Describe the circumstances under which carbon monoxide poisoning may occur, the signs and symptoms, ways to detect it and minimize its effects. Include the potential for carbon monoxide poisoning from ground air conditioning units or as a result of a ground heating unit (e.g. Herman-Nelson, Ground Power Unit).

1.2B Effects of Altitude

1.2B.1 Define what is meant by decompression sickness and describe the physiological effects of pressure changes on gases in the body. Define "safe" times between scuba diving and flight.

1.2B.2 Define what is meant by hypoxia, the hazards associated with it, signs and symptoms, ways to detect it and minimize its effects.

1.2B.3 Define time of useful consciousness and factors affecting it.

1.2B.4 Describe the effects of oxygen deficiency on human performance and identify the importance in recognizing these signs and symptoms in other crew members.

1.2B.5 Identify persons most susceptible to the effects of hypoxia.
