Narrative:
The memphis VOR has been OTS for several weeks and is planned to be out for some time yet. Pilots have questioned the legality of being cleared for the standard approachs, particularly the middy and wallet since they have no way to establish an inbound radial in the event of radio failure. Furthermore, some of the missed approachs require VOR azimuth information and approach refuses to issue alternate missed approach procedures unless specifically queried by the pilot. I believe that in the interest of safety and brevity that approach should issue alternate missed approach instructions at the time they clear an aircraft for approach. Otherwise it is likely to be overlooked until the aircraft is already missing the approach and then he may not be able to talk to anyone due to workload and frequency being used. Also, other arrs should be instituted temporarily to preclude confusion in the event (albeit slight) of radio failure.

Title: ACR MLG COMPLAINT ABOUT ATC PROC WITH INVOLVED NAVIGATIONAL AID OUT OF SERVICE.
Narrative: THE MEMPHIS VOR HAS BEEN OTS FOR SEVERAL WEEKS AND IS PLANNED TO BE OUT FOR SOME TIME YET. PLTS HAVE QUESTIONED THE LEGALITY OF BEING CLRED FOR THE STANDARD APCHS, PARTICULARLY THE MIDDY AND WALLET SINCE THEY HAVE NO WAY TO ESTABLISH AN INBND RADIAL IN THE EVENT OF RADIO FAILURE. FURTHERMORE, SOME OF THE MISSED APCHS REQUIRE VOR AZIMUTH INFO AND APCH REFUSES TO ISSUE ALTERNATE MISSED APCH PROCS UNLESS SPECIFICALLY QUERIED BY THE PLT. I BELIEVE THAT IN THE INTEREST OF SAFETY AND BREVITY THAT APCH SHOULD ISSUE ALTERNATE MISSED APCH INSTRUCTIONS AT THE TIME THEY CLR AN ACFT FOR APCH. OTHERWISE IT IS LIKELY TO BE OVERLOOKED UNTIL THE ACFT IS ALREADY MISSING THE APCH AND THEN HE MAY NOT BE ABLE TO TALK TO ANYONE DUE TO WORKLOAD AND FREQ BEING USED. ALSO, OTHER ARRS SHOULD BE INSTITUTED TEMPORARILY TO PRECLUDE CONFUSION IN THE EVENT (ALBEIT SLIGHT) OF RADIO FAILURE.
