Safety Recommendation History
From: NTSB
To: FAA
Date: 12/10/1987
Response: The change to the Minimum Operational Performance Standard Drafting Guide of the Radio Technical Commission for Aeronautics (RTCA) as approved by the RTCA Executive Committee for inclusion in the next general revision of the drafting guide is acceptable in fulfilling the intent of Safety Recommendation A-81-74. We have classified this recommendation as "Closed--Acceptable Action."

From: FAA
To: NTSB
Date: 10/13/1987
Response: BASED ON MEETINGS BETWEEN NTSB STAFF AND FAA STAFF, FAA SUB MITTED A SUGGESTED CHANGE TO THE MOPS DRAFTING GUIDE TO RTCA FOR APPROVAL. THE CHANGE ADDS THE PROVISION: A) THE CAPA BILITY OF RECALLING THE ACTIVE FACILITY AT ANY TIME FOR THE PURPOSE OF IDENTIFICATION. TO SECTION 2.1.8 OF THE MOPS DRAFTING GUIDE.

From: NTSB
To: FAA
Date: 8/3/1987
Response: On May 13, 1987, our staff met with the FAA's staff to discuss the wording of the Radio Technical Commission for Aeronautics (RTCA) Executive Committee's paragraph 2.1.8, Display of Navigation Facility Identification. The following day the staff again met in order to arrive at some wording that would be agreeable to both the Safety Board and the FAA thereby enabling this recommendation to be resolved in a satisfactory manner. At this second meeting agreement was reached on the wording of paragraph 2.1.8 to the Minimum Operational Performance Standards Drafting Guide, referenced in the September 22, 1986, letter of Mr. Thomas E. McSweeny. The first portion of this paragraph, after the note, should read as follows: "The frequency, or paired channel or other identification of the active facility of facilities being used for navigational guidance shall be displayed at all times. If this is not possible, the pilot shall have the capability of recalling the active facility at any time for the purpose of visual identification. Equipment having this recall capability shall include the following requirements:..." We appreciate the FAA's further assistance in this matter and urge that the wording developed by our recent staff meetings be submitted to the RTCA for approval. Pending your further response, this recommendation is classified as "Open-- Acceptable Action."

From: FAA
To: NTSB
Date: 3/30/1987
Response: AN AD HOC GROUP WAS FORMED TO REVIEW THE BASIS FOR THIS RECOMMENDATION AND TO FORMULATE CORRECTIVE ACTION. AT THE REQUEST OF THE AD HOC GROUP, THE RADIO TECHNICAL COMMISSION FOR AERONAUTICS (RTCA) EXECUTIVE COMMITTEE APPROVED PARAGRAPH 2.1.8, DISPLAY OF NAVIATION FACILITY INDENTIFICATION, TO THE MINIMUM OPERATIONAL PERFORMANCE STANDARDS (MOPS) DRAFTING GUIDE. I CONSIDER THE FAA'S ACTION TO BE COMPLETED ON THIS RECOMMENDATION.

From: FAA
To: NTSB
Date: 2/2/1987
Response: NO RESPONSE RECEIVED SINCE MARCH 5, 1982.

From: NTSB
To: FAA
Date: 2/2/1987
Response: The FAA's responses of October 27, 1981, and March 5, 1982, indicated that actions were being taken to implement the intent of this recommendation. In our followup letter of April 2, 1982, we expressed our appreciation for the FAA's intended actions and, pending a further response, we classified this recommendation in an "Open--Acceptable Action" status. We have not received a further response. We are anxious to see this old recommendation satisfactorily resolved and would appreciate receiving an updated status report.

From: NTSB
To: FAA
Date: 12/15/1981
Response: We note that the FAA plans to review the feasibility of including a new requirement in future radio navigation instrument design criteria. This will insure that all frequencies or station identifiers providing essential navigational information (directional guidance or distance) are displayed in a manner so that the source of the navigational signal is readily discernible by the pilot. Pending the FAA's further response, this recommendation is held in an "Open--Acceptable Action" status.

From: FAA
To: NTSB
Date: 10/27/1981
Response: FAA LTR: IN ORDER TO SATISFY THE INTENT OF THIS RECOMMENDATION, WE PLAN TO REVIEW THE FEASIBILITY OF INCLUDING A NEW REQUIREMENT IN FUTURE RADIO NAVIGATION INSTRUMENT DESIGN CRITERIA. THIS ADDITION WOULD INSURE THAT ALL FREQUENCIES OR STATION IDENTIFIERS PROVIDING ESSENTIAL NAVIGATIONAL INFORMATION (DIRECTIONAL GUIDANCE OR DISTANCE) BE DISPLAYED IN SUCH A WAY THAT THE SOURCE OF THE NAVIGATIONAL SIGNAL CAN BE READILY DISCERNED BY THE PILOT.
