- Chapter 17: Aeromedical Factors › Vision in Flight › Night Blind Spot
Night Vision There are many good reasons to fly at night, but pilots must keep in mind that the risks of night flying are different than during the day and often times higher. [Figure 17-16] Pilots who are cautious ... educated on night-flying techniques can mitigate those risks and become very comfortable and proficient in the task. Night Blind Spot It is estimated that once fully adapted to darkness, the rods are 10,000 times more sensitive to light…
- Chapter 17: Aeromedical Factors › Vision in Flight › Night Vision Protection
This precaution increases the rate of dark adaptation at night and improves night visual sensitivity. Oxygen Supply Unaided night vision depends on optimum function and sensitivity of the rods of the retina. Lack of oxygen to the rods (hypoxia) significantly ... reduces their sensitivity. Sharp clear vision (with the best being equal to 20–20 vision) requires significant oxygen especially at night. Without supplemental oxygen, an individual’s night vision declines measurably at pressure altitudes above 4,000 feet. As altitude…
- Chapter 17: Aeromedical Factors › Vision in Flight › Scanning Techniques
Figure 17-18. Scanning techniques. Off-center viewing is another type of scan that pilots can use during night flying. It is a technique that requires an object be viewed by looking 10° above, below, or to either side ... object. [Figure 17-19] In this manner, the peripheral vision can maintain contact with an object. With off-center vision, the images of an object viewed longer than 2 to 3 seconds will disappear. This occurs because the rods reach…
- Chapter 16: Navigation › Aeronautical Charts › Sectional Charts
Aeronautical Charts An aeronautical chart is the road map for a pilot flying under VFR. The chart provides information that allows pilots to track their position and provides available information that enhances safety. The three aeronautical charts used ... pilots are: • Sectional • VFR Terminal Area • World Aeronautical A free catalog listing aeronautical charts and related publications including prices and instructions for ordering is available at the Aeronautical Navigation Products website: www.aeronav.faa.gov. Sectional Charts Sectional charts are the most common…

mechanic to ensure compliance with the regulation and safe installation. (d) Do not solely rely on GPS for VFR navigation. No design standard of accuracy or integrity is used for a VFR GPS receiver. VFR GPS receivers should be used ... conjunction with other forms of navigation during VFR operations to ensure a correct route of flight is maintained. Minimize head-down time in the aircraft by being familiar with your GPS receiver’s operation and by keeping eyes outside scanning…
