Define Stress
The nonspecific response of the body to any demand placed upon it
Four Types of Stressors
- Psychosocial (Job, Illness, Family)
- Cognitive (Musts/Shoulds)
- Physiological (Self-Imposed)
- Environmental (Altitude, Speed, Hot/Cold)
Define Fatigue
The state of feeling tired, weary, or sleepy that results from periods of anxiety, exposure to harsh environment, or loss of sleep
Define Spatial Disorientation
The erroneous inability to determine one’s position, attitude and motion relative the earth or significant objects.
Prevention of SD
- Never fly VMC and IMC at the same time
- Never fly without visual reference
- Avoid fatigue, smoking, hypoxia, anxiety
- Trust the instruments, proper scans
Treatment of SD
- Delay intuitive actions
- Refer to instruments
- Transfer controls to other pilot
The sensory inputs the provide orientation and equilibrium are
Visual, Vestibular, and Proprioreceptive
Relative motion
Falsely perceived self-motion in relation to the motion of another object
Sensory Illusion
A false perception of reality caused by the conflict of orientation information from one or more mechanisms of the equilibrium
Otolith Organ
Linear Acceleration
Semicircular Canal
Angular Acceleration
Hypoxia
When the body lacks Oxygen
Hypoxic Hypoxia
Occurs when there is not enough Oxygen in the air or when decreasing atmospheric pressure prevents diffusion of Oxygen from the lungs to the bloodstream
Hypemic Hypoxia
Reduction in blood’s Oxygen carrying capacity (i.e. Carbon Monoxide, Nitrites, Sulfa Drugs)
Stagnant Hypoxia
Blood’s Oxygen carrying capacity is adequate but circulation is inadequate (i.e. Blood flow disruption or extreme gravitational forces)
Histotoxic Hypoxia
Interference with the use of Oxygen by poisoning body tissues (i.e. Alcohol, Narcotics or poisons such as Cyanide)
Types of Drag
- Parasite
- Profile
- Induced
- Total
Parasitic Drag
Non-lifting portions of helicopter
Profile Drag
Friction of rotor blades through air
Induced Drag
Production of lift. Higher the AOA the more there is
Total Drag
Sum of all drag
