What is the best visual reporting point for an aircraft flying a VFR flight above a hilly area?
Visual reporting points are prominent buildings or landmarks that can be visually easy to identify from the air.
The choice of ground features is critical, as things that show up well on maps do not necessarily show up well from the air. So, among others, you should also consider the uniqueness and the contrast of the ground features.
After examining the options given below the answer, we come to the following conclusions:
- The contrast of an object to its background has a notable effect on its visibility. If contrast is high (for example a valley against a hilly area), then the range at which objects can be seen is increased.
- A hill or a slightly steeper hillside within a hilly area does not provide uniqueness.
- Also, few small rivers that leave a big river may provide contrast, regarding the colours against the surrounding environment, but they are not unique. The big river at its own could be a preferable ground feature as a visual reporting point contrary to the few small rivers.
