Precision approach radar scope.
A component of a GCA (ground-controlled approach) system, which vectors incoming traffic until it is handed over to the precision approach radar (PAR) controller or established on the ILS (instrument landing system). The system provides target information in the range and the azimuth while information on target information is not available. The pilot is vectored onto the final approach so that he or she can be handed over to the PAR controller or can carry out the ILS approach.
