Direct questions through appropriate facility/service center office staff
to the Office of Primary Interest (OPI)
e. 2-3-2. AREA/ROUTE BRIEFING
PROCEDURES and 2-3-3. MONITORING
The requirement for summarizing weather for TIBS
broadcasts will be discontinued. TIBS procedures are
modified to take advantage of automation capabilities, to
modernize out-of-date requirements, and to discourage
the practice of misusing TIBS as a substitute for a standard
weather briefing. Recording accuracy would be assured
by continuous software data sampling on the multiple data
feeds into the FS21 system. If unexpected data (garbled or
missing text, etc.) appear, the National Weather Service
(NWS), the FS21 Data Center Supervisor, the Recording
Correction Specialist (RCS), and the National Operations
Center (NOC) would be alerted. The RCS will perform
manual intervention of the TIBS data stream, through
access to the TIBS creation process. Consultation with
NWS, as necessary, would provide corrected data.
Redundancy (DCA and FTW Data Centers and Richland,
WA, and Madison, AL, NOCs), and failure alarms on the
TIBS servers ensure the availability of the TIBS product.
In addition to continuous data sampling, the recorded
product will be monitored by quality assurance once each
shift, to ensure the clarity and accuracy of the broadcast.
This change cancels and incorporates N JO 7110.466,
Automation of Telephone Information Briefing Service
(TIBS) and Hazardous Inflight Weather Advisory Service
(HIWAS) Broadcasts, effective April 27, 2007.
f. 2-4-3. CONTENT
The requirements for HIWAS are changed to eliminate
mandatory summarization. Also the requirement to
include weather considered significant but not already
contained in a current hazardous weather advisory is
removed. HIWAS will include a verbatim text-to-voice
announcement of all current hazardous weather advisories.
When two or more advisories are effective during the
same timeframe, on the same outlet or group of outlets,
the software will precede the text of each advisory with a
summary list of effective advisories, allowing the pilot to
listen to the full advisory text on the broadcast or to
contact Flight Watch or Flight Service, as appropriate, for
an update. Also, the NOTE in subparagraph d to “delete
all reference to Flight Watch when not available. . . .” is
deleted with the addition of the “as appropriate” remark
in the closing statement. This change cancels and
incorporates N JO 7110.466, Automation of Telephone
Information Briefing Service (TIBS) and Hazardous
