Answer 1

There’s a system called “ILS”, Instrument Landing System. That basically consists of a few transponders on the ground near the airport. The plane receives the signals and can calculate it’s current position, speed, descent rate and angle of descent from these signals. Pilots see this on their screens and can land perfectly.
