6 Hour Flight Restriction - CORRECT ANSWER - Centrifuge Run(high G)- Min.
6hrs and no side effect remain.
12 Hour Flight Restrictions (ASIA) - CORRECT ANSWER - Alcohol
Simulator Sickness
Immunizations
Anesthesia (local or Regional)
24 Hour Flight Restrictions (PHDs) - CORRECT ANSWER - Plasma Donation
Hypobaric Chamber Flights (>25k ft. P is restricted to 10k)
Decompression >10k ft.
Scuba diving
48 Hour Flight Restrictions - CORRECT ANSWER - Anesthesia (general, spinal
or epidural)
72 Hour Flight Restrictions - CORRECT ANSWER - Blood Donation 200cc or
more
Define of Stress - CORRECT ANSWER - Is the body's nonspecific response to
any demand placed upon it.
,Self-Imposed Stressors (DEATH) - CORRECT ANSWER - Drugs
Exhaustion
Alcohol
Tobacco
Hypoglycemia (low Blood Sugar)
4 Types of Stress - CORRECT ANSWER - Psychosocial- Life events (little
control)
Environmental- Weather (little control)
Cognitive- Perception of self/situation
Physiological- Self Imposed (significant control)
Hypoxia Definition - CORRECT ANSWER - State of Oxygen deficiency in the
body for any reason.
4 Types of Hypoxia - CORRECT ANSWER - Hypoxic- < Pressure Oxygen (high
alt. >10k)
Hypemic- < Oxygen-Carrying capacity of the blood (CO2)
Histotoxic- < ability to transfer O2 from blood to tissue
Stagnant- < ability to circulate blood (G force, Heart Fail)
4 Stages of Hypoxia - CORRECT ANSWER - Indifference: 0' to 10,000'
Compensatory: 10,000' to 15,000'
,Disturbance: 15,000' to 20,000'
Critical: Above 20,000'
Prevention of Hypoxia (UPL) - CORRECT ANSWER - Use Supplemental O2
Pressurize Cabin
Limit time at Altitude
Treatment of Hypoxia - CORRECT ANSWER - Give 100% O2 if not available
Descend below 10k ft.
What is Spatial Disorientation - CORRECT ANSWER - An individual's inability
to determine their position, attitude, and motion relative to the Earth's Surface.
3 Types of Spatial Disorientation - CORRECT ANSWER - Type I
(Unrecognized): Most dangerous, pilot does not perceive anything is wrong.
Example Height/ Depth Perception Illusion.
Type II (Recognized): Pilot perceives something is wrong, but may not recognize it
as SD. Thinking Instrument failure but not true. Example Graveyard Spiral
Type III (Incapacitating): Pilot experiences such an overwhelming sensation that he
cannot orient himself using visual cues or instruments. Not fatal if copilot can gain
control of the aircraft (Transfer Controls). Example Coriolis Illusion
, Prevention of Spatial Disorientation (Never, Never, Avoid, Trust) - CORRECT
ANSWER - Never fly VMC + IMC
Never Fly w/o visual ref points
Avoid: Fatigue, Hypoxia, Anxiety, Smoking, Hypoglycemia
Trust Instruments
Treatment of Spatial Disorientation - CORRECT ANSWER - Delay Intuitive
Action
Rely on & Use Instruments (develop a good crosscheck)
Transfer Controls (rare for both pilots to have SD)
3 Sensory Systems used to maintain Equilibrium - CORRECT ANSWER -
Visual- Most reliable, 80% of orientation
Proprioceptive- Pressure on skin, muscles and joints
Vestibular- Inner ear detects motion and gravity (semicircular canals and otolith
organ)
2 Types of Vestibular Illusions - CORRECT ANSWER - Somatogyral-
(Semicircular canals) (All 3 Axis) (Angular Acc/Dec)
Somatogravic- (Otolith organ) (Gravity & Linear Acc/Dec)
Somatogyral Illusions - CORRECT ANSWER - Leans- (Most common) Feels
straight & level, but attitude indicator shows slight bank. The pilot will level wings
and lean in opposite direction until sensation subsides.
