Time Of Day

Time Of Day refers to the period of the day when an aviation operation takes place. It is an important factor in aviation as it affects the visibility, weather conditions, and air traffic. The time of day is divided into three categories: day, night, and civil twilight. Daytime is defined as the period from sunrise to sunset. Nighttime is defined as the period from sunset to sunrise. Civil twilight is the period when the sun is below the horizon but its rays illuminate the sky. The time of day affects the pilot's ability to see and avoid other aircraft, as well as the visibility of the runway and surrounding terrain. It also affects the air traffic control procedures and the availability of certain navigation aids.
