Narrative:

Whenever the GS of an ILS is OTS and the facility is using the ILS approach, the approach is called ILS. I understand that the approach procedure is called an ILS with the GS OTS. I realize that this is the way it has been classified for yrs. I recommend that they change it to read a localizer approach in the ATIS and approach control call it a localizer approach. All of the equipment that I currently fly will let me know if the GS is OTS. Some of the pilots in our system are not so lucky and they are flying around with old equipment. Some of the old equipment will give you a small flag that the ILS is not receiving the GS but it is very small. The GS indication is visible and centered showing that the aircraft is right on the correct glide path (even though it might not be) if the pilot was not wary what was happening. I feel this could happen to a pilot especially if he was single pilot, behind on the approach, a little rusty, tired, etc. By changing the terminology, I feel safety would be enhanced. Callback conversation with reporter revealed the following information: reporter restated mostly what was contained in his report. He strongly felt and suggested for safety reasons that a localizer procedure be added and used whenever an airport ILS glide path is OTS.

Title: RPTR RECOMMENDS, WHEN AN ILS SYS IS BEING USED WITH THE GLIDE PATH GS UNUSABLE, THAT ATC CTLRS USE THE PHASE 'CLRED FOR LOC APCH.'

Narrative: WHENEVER THE GS OF AN ILS IS OTS AND THE FACILITY IS USING THE ILS APCH, THE APCH IS CALLED ILS. I UNDERSTAND THAT THE APCH PROC IS CALLED AN ILS WITH THE GS OTS. I REALIZE THAT THIS IS THE WAY IT HAS BEEN CLASSIFIED FOR YRS. I RECOMMEND THAT THEY CHANGE IT TO READ A LOC APCH IN THE ATIS AND APCH CTL CALL IT A LOC APCH. ALL OF THE EQUIP THAT I CURRENTLY FLY WILL LET ME KNOW IF THE GS IS OTS. SOME OF THE PLTS IN OUR SYS ARE NOT SO LUCKY AND THEY ARE FLYING AROUND WITH OLD EQUIP. SOME OF THE OLD EQUIP WILL GIVE YOU A SMALL FLAG THAT THE ILS IS NOT RECEIVING THE GS BUT IT IS VERY SMALL. THE GS INDICATION IS VISIBLE AND CTRED SHOWING THAT THE ACFT IS RIGHT ON THE CORRECT GLIDE PATH (EVEN THOUGH IT MIGHT NOT BE) IF THE PLT WAS NOT WARY WHAT WAS HAPPENING. I FEEL THIS COULD HAPPEN TO A PLT ESPECIALLY IF HE WAS SINGLE PLT, BEHIND ON THE APCH, A LITTLE RUSTY, TIRED, ETC. BY CHANGING THE TERMINOLOGY, I FEEL SAFETY WOULD BE ENHANCED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR RESTATED MOSTLY WHAT WAS CONTAINED IN HIS RPT. HE STRONGLY FELT AND SUGGESTED FOR SAFETY REASONS THAT A LOC PROC BE ADDED AND USED WHENEVER AN ARPT ILS GLIDE PATH IS OTS.
