- Definição2
- A type of radar used at an airport to guide an aircraft through the final stages of landing. The radarscope has two plots: one showing the position of the aircraft along an extended center line of the runway, and the other showing the position of the aircraft as it descends along the glide slope to the runway. The radar operator directs the pilot to change heading or adjust the descent rate to keep the aircraft on a path that allows it to touch down at the correct spot on the runway.

- Nota adicional1
- Precision approach radars are designated to enable pilots of aircraft to be given guidance by radiocommunication during the final stages of the approach to land.
- Nota adicional2
- Precision approach radar (PAR) is the part of the precision approach radar system that provides the range, azimuth and elevation data when the aircraft is in the final stages of approach.
