People assume that its easier to fly an airplane during the day because we can look out of the window and see where we are going, the same way we do in a car to navigate and keep clear of other traffic. But flying an airplane is very different from driving a car and much more precise. An airplane has sophisticated navigation technology on board that allows a pilot to fly without visual sightings by relying entirely on the aircraft’s instruments. This is known as instrument flight rules, and commercial pilots abide by it very frequently during a flight, such as when flying through clouds or flying at night.
