Safety Recommendation History
From: NTSB
To: FAA
Date: 12/17/1991
Response: The Safety Board acknowledges that the Hawaiian Islands Reporting Service Area is operated by the Flight Service Station. The intent of this recommendation was to request the FAA to determine the feasibility of incorporating U.S. military ground- based radar facilities into the area of radar coverage established for the Honolulu Center/Radar Approach Control. The Safety Board notes that the FAA has reviewed this recommendation and believes that while it is possible to integrate civil/military ground-based radar into the Hawaiian Islands Reporting Service area, it has no clear benefit. Therefore, the Safety Board agrees with the FAA position and classifies Safety Recommendation A-90-138 as "Closed--Reconsidered."

From: NTSB
To: FAA
Date: 5/22/1991
Response: Safety Recommendation A-90-138 recommends that the FAA establish procedures to incorporate existing FAA and U.S. military ground-based radar facilities into the Hawaiian Islands Reporting Service area. The Safety Board notes that the FAA is discussing this issue with the appropriate military authorities. Pending further information, Safety Recommendation A-90-138 is classified as "Open--Acceptable Response."

From: FAA
To: NTSB
Date: 5/15/1991
Response: THE FAA HAS REVIEWED THIS RECOMMENDATION AND BELIEVES THAT WHILE IT IS POSSIBLE TO INTEGRATE CIVIL/MILITARY GROUND-BASED RADAR INTO THE HAWAIIAN ISLANDS REPORTING SERVICE AREA, IT HAS NO CLEAR BENEFIT. THE HAWAIIAN ISLANDS REPORTING SERVICE AREA IS OPERATED BY THE FLIGHT SERVICE STATION--A NONAIR TRAFFIC CONTROL FACILITY. RADAR FLIGHT FOLLOWING WHICH IS ALREADY AVAILABLE TO THE PILOT IS OPERATED BY THE HONOLULU COMBINED CENTER/RADAR APPROACH CONTROL--AN AIR TRAFFIC CONTROL FACILITY. THESE TWO FUCTIONS HAVE SEPARATE REQUIREMENTS AND RESPONSIBILILTIES WHICH PROHIBIT THEM FROM BEING INCORPORATED. AS WITH THE HAWAIIAN ISLANDS REPORTING SERVICE AREA, RADAR FLIGHT FOLLOWING IS NOT MANDATORY AND MUST BE REQUESTED BY PILOTS FLYING UNDER VISUAL FLIGHT RULES. SINCE BOTH SERVICES ARE AVAILABLE TO THE PILOT ON REQUEST, THE FAA DOES NOT SEE ANY BENEFIT TO BE GAINED BY INCORPORATING THESE TWO SERVICES.

From: FAA
To: NTSB
Date: 2/8/1991
Response: THE FAA IS DISCUSSING THIS ISSUE WITH THE PERTINENT U.S. MILITARY AUTHORITIES AND WILL ADVISE THE SAFETY BOARD OF ITS COURSE OF ACTION AS SOON AS A DECISION REGARDING THE PROCEDURES HAS BEEN MADE.
