[Figure 17-19] In this manner, the peripheral vision can maintain contact with an object.

Can you be a pilot with blue eyes?

Good fighter pilots in the air usually have blue eyes. All pilots must come of good, sound stock, and must pass a strict medical examination. This includes tests to find whether the would-be – pilot can withstand the strain of – flying in all climates and all altitudes. There are also breath-taking and balancing tests.

What do pilots do at night?

Pilots rely on flight instruments, navigation sensors and weather sensors (primarily radar) instead of normal vision when flying at night or passing through cloud. The aircraft itself has multiple lights on its exterior to help pilots land when it’s dark (and to help others spot the plane).

Can I fly at night VFR?
