Private Pilot Private Practice Exam

To prepare for night flying, it is vital for pilots to avoid bright white lights before the flight. This practice helps in allowing the eyes to adjust to lower light levels, a process known as dark adaptation. When bright lights, especially those emitted by screens or direct light sources, are encountered, they can temporarily impair the ability of the eyes to see in low-light conditions. By minimizing exposure to such lights prior to takeoff, pilots can enhance their night vision capabilities, making it easier to detect other aircraft, read instruments, and navigate in the dark environment.

In contrast, increasing glare exposure or looking directly at bright lights would hinder night vision, making it more difficult for a pilot to see clearly during nighttime flights. Using sunglasses during flight could potentially be unhelpful if they block essential light needed for adjusting to the darkness; they also may not provide benefits if not specifically designed for night flying, such as reducing glare without overly dimming the surroundings.
