  1. Fatigue in flight primarily affects a pilot's performance by:

    Answer: Slowing reaction time, impairing judgment, and reducing vigilance

    Fatigue degrades all cognitive and motor functions, including reaction time, decision-making, and the ability to maintain situational awareness.

  2. Which drug category is generally considered SAFE for pilots to use and fly?

    Answer: None—any medication requires medical certificate review before flying

    Any medication that affects the CNS can impair pilot performance; pilots should consult an Aviation Medical Examiner before flying while on any medication.

  3. At night, a pilot should scan for traffic using:

    Answer: Peripheral off-center scanning with regular eye movements

    Because rods (night-vision cells) are concentrated around the periphery of the retina, off-center viewing activates more rods and makes dim lights more visible.

  4. Which statement about prescription eyeglasses and contact lenses for certificated pilots is correct?

    Answer: Pilots who need corrective lenses must wear them and carry an additional pair

    A medical certificate issued with the limitation 'must wear corrective lenses' requires the pilot to wear them and have a spare pair available in flight.

  5. What effect does high cabin altitude have on the ability to see at night?

    Answer: Night vision deteriorates because rod cells require more oxygen than cone cells

    Rod cells are highly oxygen-sensitive; even mild hypoxia at 5,000 feet can noticeably degrade night vision, worsening significantly at higher altitudes.

  6. A pilot notices that a ground light appears to drift slowly sideways while on a long final approach at night. This is MOST likely:

    Answer: Autokinesis—an illusion of movement of a stationary light

    Autokinesis is a visual illusion where a stationary point of light appears to move when stared at in a dark environment without reference points.

  7. Which scenario BEST describes 'stagnant hypoxia'?

    Answer: Reduced oxygen delivery to tissues due to impaired blood circulation

    Stagnant hypoxia occurs when normal blood oxygen content cannot reach the tissues due to circulatory problems, such as shock, heart failure, or G-force pooling.
