PAR = Precision Approach Radar (A GCA with both glide path and centerline guidance. ASR = Air Surveillance Radar (A GCA with centerline guidance only, using recommended minimum altitudes at various ranges from touchdown) Both ASR and PAR are GCA.

In those days, it was GCA -- Please explain the difference between GCA and PAR....... PAR is part of the GCA http://en.wikipedia.org/wiki/Precision_Approach_Radar http://en.wikipedia.org/wiki/Ground-Controlled_Approach I worked as a Radio Repairman at Williams AFB in the late 70's . Our GCA was located beside the Control tower. It had 2 PAR Positions and three ASR positions. It does not actually control airspace it only provides guidance for landing. If a GCA like the one at Williams was to control airspace it would not be a GCA it would be a RAPCON (Runway APproach CONtrol) A brief note on ASR approaches. ASR does not determine Altitude information. That is coming from the Aircrafts altimeter through the aircraft transponder and the decoded by the radars IFF reciever which then places that information on the Controllors ASR scope. Most of you already know this but I though I'd add it for those who don't John Hairell ) former GCA/PAR controller |
