ARMY AEROMEDICAL ACTUAL EXAM
What is Spatial Disorientation - ANSWER-An individual's inability to determine their position, attitude, and motion relative to the Earth's Surface.
- Types of Spatial Disorientation - 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) - ANSWER-Never fly VMC + IMC Never Fly w/o visual ref points 1 / 4

Avoid: Fatigue, Hypoxia, Anxiety, Smoking, Hypoglycemia
Trust Instruments
Treatment of Spatial Disorientation - ANSWER-Delay Intuitive Action Rely on & Use Instruments (develop a good crosscheck) Transfer Controls (rare for both pilots to have SD)
- Sensory Systems used to maintain Equilibrium - 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)
- Types of Vestibular Illusions - ANSWER-Somatogyral- (Semicircular canals) (All 3 Axis) (Angular
- / 4
Acc/Dec) Somatogravic- (Otolith organ) (Gravity & Linear Acc/Dec)

3 Somatogyral Illusions - 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.
Graveyard Spin-(Usually occurs in fix wing) Piot enters spin for several seconds. Semicircular canals reach equilibrium. Pilot levels out and feel he is spinning in opposite direction and reenters original spin.
Coriolis Illusion- (Most dangerous) Prolong turn with rapid head motion activates all 3 axis of the semicircular canal resulting in an overwhelming head over heels tumbling sensation. ( Must transfer controls)
Somatogravic Illusions - ANSWER-Oculogravic- During Rapid Acc/Dec the pilot will sense nose up or nose down. Pilot may over control the acft into an extreme nose low or high att.
Elevator- Upward acceleration (updraft), eyes tract down, pilot will sense nose up. Pilot may push acft into nose low att. intensifying the illusion.
Oculoagravic- Downward Acc. (downdraft/ Auto's) During decent eyes track up, pilot will sense nose low. Pilot may pull the acft into a nose high att. intensifying the illusion.

4 Fatigue Definition - ANSWER-A state of feeling tired, weary, or sleepy that results from prolonged mental or physical work, extended periods of anxiety, exposure, to harsh environments, or loss of sleep. Boring or monotonous tasks can increase fatigue.
- Types of Fatigue - ANSWER-Acute-(Minor) Associated with activity over 2 regular sleeping
- Hour Flight Restriction - ANSWER-Centrifuge Run(high G)- Min. 6hrs and no side effect
periods. Need one regular sleep period to recover. Characterized by Irritability, Inattention, Distractibility, loss of Accuracy/Control, Lack of Awareness of Errors.
remain.
12 Hour Flight Restrictions (ASIA) - ANSWER-Alcohol Simulator Sickness Immunizations Anesthesia (local or Regional)
24 Hour Flight Restrictions (PHDs) - ANSWER-Plasma Donation Hypobaric Chamber Flights (>25k ft. P is restricted to 10k) Decompression >10k ft.Scuba diving
48 Hour Flight Restrictions - ANSWER-Anesthesia (general, spinal or epidural)
