AM Aerospace Exam
Question 1. Which gas law describes the inverse relationship between
pressure and volume at constant temperature?
A) Boyle's Law
B) Charles's Law
C) Dalton's Law
D) Henry's Law
Answer: A
Explanation: Boyle's Law states that at constant temperature, pressure
and volume are inversely proportional.
Question 2. What is the primary cause of hypoxia in an unpressurized
aircraft at high altitude?
A) Increased carbon dioxide levels
,AM Aerospace Exam
B) Reduced oxygen partial pressure
C) Decreased carbon monoxide levels
D) Increased nitrogen levels
Answer: B
Explanation: At high altitude, the partial pressure of oxygen decreases,
leading to hypoxia due to insufficient oxygen supply.
Question 3. Which symptom is most characteristic of decompression
sickness (DCS)?
A) Sudden chest pain
B) Joint pain and skin mottling
C) Loss of vision
D) Hearing loss
,AM Aerospace Exam
Answer: B
Explanation: DCS often presents with joint pain, skin mottling, and
neurological symptoms due to bubble formation in tissues.
Question 4. Which type of barotrauma involves pain in the teeth caused
by rapid changes in pressure?
A) Barotitis media
B) Barosinusitis
C) Barodontalgia
D) Gastrointestinal barotrauma
Answer: C
Explanation: Barodontalgia is dental pain caused by rapid pressure
changes, often during ascent or descent.

Question 5. What is the primary physiological effect of +Gz forces on the
body?
A) Increased blood flow to the brain
B) Blood pooling in the lower extremities
C) Reduced cardiac output
D) Increased intracranial pressure
Answer: B
Explanation: +Gz forces cause blood to pool in the lower extremities,
risking G-LOC if not countered properly.
Question 6. Which maneuver is most effective in preventing G-LOC
during high-G exposure?
A) Valsalva maneuver
B) Anti-G straining maneuver (AGSM)
