PPL PPL Pilot Health and Human Factors 3

Question 1

Why is scuba diving before a flight potentially dangerous?

Accepted Answer

Nitrogen absorbed during diving can form bubbles in the bloodstream at altitude, causing decompression sickness

Answer

It causes ear infections that impair in-flight hearing

Answer

It causes hypoxia at normal general aviation altitudes

Answer

It permanently impairs night vision

Question 2

What is the vestibular system's key limitation during instrument flight?

Accepted Answer

It cannot sustain accurate attitude sensing without visual references, leading to dangerous disorientation in IMC

Answer

It provides accurate pitch and roll information under all flight conditions

Answer

It becomes more accurate as a pilot gains experience in IMC

Answer

It correctly senses coordinated turns without instrument reference

Question 3

Which medication class is generally considered incompatible with flight duties?

Question 4

What does pilot 'currency' mean and how does it differ from 'proficiency'?

Accepted Answer

Currency means meeting minimum legal recent experience requirements; proficiency means actual skill and competence

Answer

They are the same thing — both require recent flight time

Answer

Currency refers to medical certificate validity; proficiency is currency plus flight review

Answer

Currency requires 3 hours of flight; proficiency requires only a written test

Question 5

What is 'tunnel vision' in the context of pilot human factors?

Accepted Answer

Excessive focus on one task causing a pilot to miss other critical cues in the cockpit or environment

Answer

A medical eye condition caused by sustained high G-forces

Answer

Reduced peripheral vision during night operations

Answer

A hypoxia symptom at high altitude

Question 6

What does FAR 61.56 require regarding the flight review?

Accepted Answer

A pilot must complete a flight review with a CFI every 24 calendar months to maintain pilot-in-command privileges

Answer

Answer

A flight review is required only after a lapse in currency of 60 days

Answer
