Question 1

What is the primary cause of vertigo (spatial disorientation) in IMC flight?

Accepted Answer

Conflict between vestibular and visual cues

Answer

Spatial disorientation in instrument meteorological conditions (IMC) occurs when vestibular (inner ear) sensations conflict with cockpit instrument indications.

Question 2

What does the Coriolis illusion cause a pilot to perceive?

Accepted Answer

Tumbling or rolling sensation when moving the head during a sustained turn

Answer

The Coriolis illusion arises when a pilot moves their head during a prolonged turn, overstimulating the semicircular canals and creating a tumbling sensation.

Question 3

What is the maximum blood alcohol concentration (BAC) allowed for military aviators before flight?

Accepted Answer

0.00% (completely sober)

Answer

Military aviation regulations prohibit any detectable alcohol in a pilot's system, requiring complete sobriety before flight.

Question 4

What is the 'graveyard spiral' and what causes it?

Accepted Answer

A progressively steepening spiral dive caused by spatial disorientation

Answer

The graveyard spiral is a progressively tightening spiral dive that develops when a pilot, disoriented in a bank, pulls back instead of rolling wings-level.

Question 5

What physiological effect does hyperventilation commonly cause in pilots?

Accepted Answer

Decreased carbon dioxide causing lightheadedness and tingling

Answer

Hyperventilation causes excessive carbon dioxide to be expelled, lowering blood CO₂ levels and producing symptoms like lightheadedness, tingling, and impaired judgment.
