In those days, it was GCA


It still is.



GCA = Ground Controlled Approach. 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.


That is today's definition. During the Berlin Airlift GCA meant
azimuth, range, and elevation radars.
