  2. Tactical Decision Aids • Define • FTW ARTCC • Description of FTW ARTCC • Types of TDAs used at FTW CWSU • TRACON • ARTCC • Forecaster produced • Automated by PACE • Forecast Tools

  3. Tactical Decision AidsDefined • Graphical forecast of elements useful to FAA Traffic Management, supervisors and dispatchers • Timeline format • Forecast Elements can be categorical or probabilistic

  4. Tactical Decision Aids (TDA) • Define • ZFW ARTCC • Description of ZFW airspace • Types of TDAs used at FTW CWSU • TRACON • ARTCC • Forecaster produced • Automated • Forecast Tools

  5. Fort Worth ARTCC Major air traffic corridors/routes: East-west traffic across the southern US DFW arrivals/departures North-south traffic from IAH-ORD and IAH-DEN as well as others

  6. FTW ARTCC Arrival Cornerposts DFW TRACON with Air traffic UKW Bowie BYP Bonham CQY Cedar Creek JENGlenrose

  7. DFW Arrival/Departure Routes DFW TRACON with Air traffic Arrival Depart Arrival 110-130 140-170 110-130 Depart Depart 140-170 140-170 Arrival Arrival 110-130 110-130 Depart 140-170

  8. Tactical Decision Aids (TDA) • Define • FTW ARTCC • Description of FTW ARTCC • Types of TDAs used at FTW CWSU • TRACON • ARTCC • Forecaster produced • Automated by PACE • Forecast Tools

  9. Types of TDAs • DFW TRACON (in use since late 90’s) • Ceilings and visibilities • Wind - north or south flow or crosswind • Precipitation type/coverage • Timeline forecast through 9 hours • Updated every 3-6 hours

  10. Types of TDAs • ARTCC Arrival and departure gate sectors (UKW, BYP ,CQY, JEN) • TS coverage • Timeline forecast through 6 hours • Updated every 3-6 hours

  11. Elements to TRACON TDA • Ceilings/Visibilities • VFR >= 3000 ft; > 5 mi • MVFR 1000 -3000 ft; 3 – 5 mi • IFR 500 – 1000 ft; 1 – 3 mi • LIFR < 500 ft ; < 1 mi • Winds • North flow • South flow • Crosswinds 20-25 kts • Precipitation • Type • TS SH RA SN etc. • Probability/Coverage • Few – VC - Prob30/40 - Tempo

  12. TRACON TDA Forecast Tools • Current METARs • Current TAF • Crosswind calculations • Via FTW CWSU web site • Precipitation forecast • Various sources • ITWS, PACE, NCWF6, Auto Nowcaster

  13. Ex. 30025G40

  14. Tactical Decision Aids (TDA) • Define • ZFW ARTCC • Airspace 101 (short version) • Types of TDAs used at FTW CWSU • TRACON • ARTCC • Forecaster produced • Automated by PACE • Forecast Tools

  15. Elements to Arrival/Departure Gate Sector TDA (Forecaster) • Precipitation (TS) Coverage • Open - < 30% • Marginal - 30-70% • Impacted >70%

  16. Data from PACE For continuous updates go to http://???.???.noaa.gov

  17. Tactical Decision Aids (TDA) • Define • ZFW ARTCC • Description of ZFW airspace • Types of TDAs used at FTW CWSU • TRACON • ARTCC • Forecaster produced • Automated • Forecast Tools

  18. Arrival/Departure Gate Sector TDA Forecast Tools • Convective Forecasting • NEXRAD • Auto Nowcaster – Thunderstorm initiation tool • TCWF – Terminal Convective Weather Forecast (ITWS) • 0-1 hour • PACE - Prototype Aviation Collaborative Effort • 0-2 hours • NCWF6 - National Convective Weather Forecast • 0-6 hours • CCFP – Collaborate Convective Forecast Product • 0-6 hours

  19. WARP NEXRAD

  20. WARP NEXRAD Mosaic • Advantages • Primary display available to ATC • Displays TS and jet routes/sectors • Animation • Disadvantages • No calculations or forecast other than CCFP • Closed system- • Cannot import products from other sources

  21. Auto Nowcaster • Displays Convective Threat • 1 hour in advance • User input required from local WFO • Type of airmass regime • Cold front, Dryline, No TS, Dvlpg Ts, Stnry Fnt, Advect, Mxd • boundaries, regions, polygons • Nudge up/down

  22. ITWS(Integrated Terminal Weather System) • Integrates several radar systems Six radars (1) NEXRAD (2) TDWRs (3) ASR-9s • TCWF – (Terminal Convective Weather Forecast) • 0 – 1 hour location of precipitation • VIL intensity

  23. PACE(Prototype Aviation Collaborative Effort) • Displays current significant thunderstorm activity • Significant thunderstorms • VIL intensity • Lightning • Echo tops > 15,000 ft. • Incorporates NCWF2 forecast (0-2 hr.)

  24. PACE(Prototype Aviation Collaborative Effort) • Plan View • TS forecast 30, 60, 90 and 120 min. • Updated every 5 minutes • Timeline display • 0-2 hr. at 5 min. intervals • Threat boxes indicate TS within 10 nm. • Major jet routes • Arrival and departure gates • Algorithms currrently very simplistic

  25. NCWF-6(National Convective Weather Forecast-6 hours) • Displays current and forecast significant thunderstorm activity • Significant thunderstorms • VIL intensity • Lightning • Echo tops > 15000 ft. • Displays forecast of activity (0-6hrs.) • Threat probability

  26. CCFP
