GCA = Ground Controlled Approach. PAR = Precision Approach Radar (A

Surveillance Radar (A GCA with centerline guidance only, using
recommended minimum altitudes at various ranges from touchdown)

Both ASR and PAR are GCA.


A surveillance approach does not necessarily include recommended minimum
altitudes.


Terminology and precision in language again. An ASR has minimum
altitudes and a "begin descent" point after which you can descend to
minimums as fast or as slowly as you choose while being guaranteed
terrain clearance. My insertion of the modifier "recommended" was bad.

Don't feel too bad Ed, Stevie's just splitting hairs again.

From an FAA controller's standpoint recommended altitudes on ASR approaches
are only provided on pilot request (see FAAO 7110.65 5-11-1).

However IIRC, either AFR 60-5 or AFCSR 60-5 required USAF final controllers
to provide them all the time even without a specific request so a USAF stick
actuator would seldom (if ever) have a need to split that particular hair.

Recommended altitudes were routinely issued until an accident at Cleveland.
Then it was on request only.
