Answer 1

Each airport has a transponder that allows planes to determine their position relative to the runway, regardless of whether or not it’s visible to the pilots. This is known as the Instrument Landing System or ILS. When pilots train for instrument flight, they actually wear a big visor that keeps them from seeing out the windshield, they have to fly and land using only the instruments.
