Safety Recommendation History
From: NTSB
To: FAA
Date: 12/18/1984
Response: The Safety Board has reviewed the Briefing Guide for Change 7 to the FAA's Air Traffic Control Handbook 7110.065C and notes that Center Weather Advisories (CWAs) are to be broadcast and generally handled similarly to SIGMET Alerts. The Safety Board understands also, from discussions with the FAA's Terminal Procedures staff, that FAA's Facility Operation and Administration Handbook 7210.3G has been changed effective on October 25, 1984, to require that CWAs be included on Automatic Terminal Information Service broadcasts. These changes to FAA Handbooks 7110.65C and 7210.3G satisfy the objectives of Safety Recommendations A-81-23, A-76-36, and A-74-14, which have been classified as "Closed--Acceptable Action."
