The published MDA for straight-in approaches will be issued to the pilot before beginning descent.Radar service is automatically terminated at the completion of a radar approach.Similarly, guidance termination and missed approach will be effected upon pilot request and, for civil aircraft only, controllers may terminate guidance when the pilot reports the runway, airport/heliport or visual surface route (point-in-space approach) in sight or otherwise indicates that continued guidance is not required.Also, if, at any time during the approach the controller considers that safe guidance for the remainder of the approach cannot be provided, the controller will terminate guidance and instruct the pilot to execute a missed approach.At the completion of the approach, controllers will terminate radar services and instruct the pilot to execute a missed approach unless at the MAP the pilot has the runway, airport or heliport in sight or, for a helicopter point-in-space approach, the prescribed visual reference with the surface is established.Normally, navigational guidance will be provided until the aircraft reaches the MAP.In addition, the pilot will be advised of the location of the Missed Approach Point (MAP) prescribed for the procedure and the aircraft's position each mile on final from the runway, airport or heliport or MAP, as appropriate.Upon commencing the approach at the Final Approach Fix (FAF), the pilot will be advised when to commence descent to the Minimum Descent Altitude (MDA) or, if appropriate, to an intermediate step-down fix Minimum Crossing Altitude and subsequently to the prescribed MDA.Since the radar information used for a surveillance approach is considerably less precise than that used for a precision approach, the accuracy of the approach will not be as great and higher minimums will apply.The pilot is furnished headings to fly to align the aircraft with the extended centerline of the landing runway.Published minimums will be issued prior to descent.Ultimately is used to provide aircraft locations over an area around an airport.If requested by the pilot, recommended altitudes will be issued at each mile, based on the descent gradient established for the procedure, down to the last mile that is at or above the MDA.The lack of vertical guidance results in higher approach minimums, as you would expect with a non-precision approach.An Surveillance Approach Radar (ASR) is a non-precision approach which provides lateral course guidance (azimuth) only, no glide slope.Radar can be used to advise pilots on other approaches so long as they are coincident with the PAR final and the PAR is in service.The decision to make a radar approach when the reported weather is below the established minimums rests with the pilot.Acceptance of a PAR or ASR by a pilot does not waive the prescribed weather minimums for the airport or for the particular aircraft operator concerned.A radar approach may be given to any aircraft upon request and may be offered to pilots of aircraft in distress or to expedite traffic, however, an ASR might not be approved unless there is an ATC operational requirement, or in an unusual or emergency situation.PAR and ASR minimums are published on separate pages in the FAA Terminal Procedures Publication (TPP).The only airborne radio equipment required for radar approaches is a functioning radio transmitter and receiver.KNUC San Clemente Radar Approach Minimums.Radar Approach Minimums Table of Contents.
