  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…

  looking directly at an object for more than a few seconds, the image of the object fades away completely (night blind spot). Peripheral vision (off center scanning) provides the only means of seeing very dim objects in the dark. Night ... Blind Spot The “Night Blind Spot” appears under conditions of low ambient illumination due to the absence of rods in the fovea. [Figure 11-3] This absence of rods affects the central 5 to 10 degrees of the visual field…

  Chapter 11: Night Operations › Preparation and Preflight

  Preparation and Preflight Night flying requires that pilots are aware of, and operate within, their abilities and limitations. Although careful planning of any flight is essential, night flying demands more attention to the details of preflight preparation and planning. Preparation ... night flight includes a thorough review of the available weather reports and forecasts with particular attention given to temperature/dew point spread. A narrow temperature/dew point spread may indicate the possibility of fog. Emphasis should also be placed on wind direction…
