Explanation of Changes

Direct questions through appropriate facility/service center office staff
to the Office of Primary Interest (OPI)

a. 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 TIBS procedures are modified to take advantage of automation capabilities, to modernize out-of-date requirements, and to discourage the practice of misusing TIBS as a substitute for a standard weather briefing.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.

b. 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 Inflight Weather Advisory Service (HIWAS) Broadcasts, effective April 27, 2007.

c. 6-1-2. FLIGHT PLANS

This change expands the use of the DVFR flight plan procedures developed in the Southwest Region to all facilities except Alaska. Affected AFSSs will now be the primary contact for DVFR operations, assigning a DVFR beacon code, and transmitting all DVFR flight plan information directly to NORAD. This new subparagraph adds the instruction to advise a pilot to activate his/her DVFR flight plan with Flight Service and that a discrete beacon code will be assigned upon activation. This change cancels and incorporates N JO 7110.470, Automated Flight Service Station (AFSS) Handling of Defense Visual Flight Rules (DVFR) Flight Plans, effective June 24, 2007.

d. 6-2-1. FLIGHT PLAN RECORDING

This change expands the use of the DVFR flight plan procedures developed in the Southwest Region to all facilities except Alaska. Affected AFSSs will now be the primary contact for DVFR operations, assigning a DVFR beacon code and transmitting all DVFR flight plan information directly to NORAD. Both Model 1 Full Capacity (M1FC) and OASIS will require flight plan entry modifications for the systems to accept the NORAD address and to transmit the DVFR flight plan correctly. Flight Services for the 21st Century will perform this process. This change cancels and incorporates N JO 7110.470, Automated Flight Service Station (AFSS) Handling of Defense Visual Flight Rules (DVFR), effective June 24, 2007.

e. 6-6-2. AMIS WITHIN AN ADIZ-DVFR, 6-6-3. FORWARDING DVFR INFORMATION, and 6-6-5. ADDRESSING DVFR FLIGHT PLAN MESSAGES

f. 7-2-3. INBOUND PRIVATE AIRCRAFT: ADIZ REQUIREMENTS

This change expands the use of the DVFR flight plan procedures developed in the Southwest Region to all facilities except Alaska. Affected AFSSs will now be the primary contact for DVFR operations, assigning a DVFR beacon code and transmitting all DVFR flight plan information directly to NORAD. This section applies to aircraft inbound to the United States from foreign departure points. This change cancels and incorporates N JO 7110.470, Automated Flight Service Station (AFSS) Handling of Defense Visual Flight Rules (DVFR) Flight Plans, effective June 24, 2007.

g. 11-1-18. VISUAL APPROACH SLOPE INDICATORS (VASIs)

This editorial change clarifies Table 11-1-8, VASI Intensity Setting, Three-Step System.
