Human Factor - Aviation Physiology (2)

At what cabin altitude do most commercial aircraft maintain cabin pressure to ensure passenger safety and comfort?

• 8.000 feet

• 10.000 feet

• 12.000 feet

• 14.000 feet

What is hypoxia in the context of aviation physiology?

• Excessive oxygen in the blood

• Reduced oxygen supply to the body tissues

• Increased carbon dioxide in the bloodstream

• Dehydration due to high altitude

Which physiological response occurs when a pilot experiences spatial disorientation?

• Decreased heart rate

• Loss of equilibrium

• Improved depth perception

• Enhanced auditory perception

Which part of the ear is responsible for maintaining balance and is affected by rapid changes in altitude?

• Outer ear

• Middle ear

• Inner ear

• Eardrum

Above what altitude do pilots need to breathe supplementary oxygen?

• 2000 ft

• 8000 ft

• 12500 ft

• 20000 ft

What is the primary symptom of hyperventilation in pilots?

• Improved concentration

• Decreased heart rate

• Dizziness and tingling sensations

• Increased blood pressure

What is the purpose of cabin pressurization in modern aircraft?

• To prevent dehydration

• To maintain oxygen levels similar to sea level

• To increase the speed of the aircraft

• To reduce the effects of turbulence

Which body system is primarily responsible for regulating balance and spatial orientation in aviation physiology?

• Respiratory system

• Nervous system

• Muscular system

• Digestive system

Which type of hypoxia is most commonly associated with high altitude flying?

• Hypemic hypoxia

• Stagnant hypoxia
