Can someone tell me the definition of an "airborne radar approach". I was unable to find the defintion in AIP. This is mentioned in the Pilots Log Book - General Guidance, in the front of the CASA issued log book. For some unknown reason it says "instrument approaches are to be credited to the pilots in the case of an airborne radar approach" I have never heard of a specific ground borne radar approach though.
Maybe it means a surveillance radar approach where the ground borne radar operator talks you down. Or overseas maybe its a GCA or ground controlled approach where you are talked down too. But either way why should both pilots in a two crew aircraft be entitled to log the "airborne radar approach" when on a normal instrument approach such as NDB, VOR, ILS, DME arrival etc only one pilot can log the instrument approach?
