TRACON Tactical Decision Aid Demonstration
2
Editing Icing Potential Grid
3
Close-up of TRACON Area DFW airport Four cornerposts
5
TRACON Status Algorithm (Graphic) FIP SIP FIS GTG TST Red, Yellow, Green Yellow? Use FIS Red, Yellow, Green Yellow Red, Green Red, Yellow, Green Display
6
TRACON Status Algorithm (Text) Inputs Initial color assessment FIP/FIS combination Icing/turbulence/thunderstorm combination
7
TRACON Status Inputs Icing Potential (FIP) Supercooled Water (SIP) Icing Severity (FIS) Turbulence (GTG) Thunderstorm (TST)
8
TRACON Status Color Assessment Green (<30) Yellow (30-60) Red (>60) Thresholds readily configured.
9
Combinations FIP/FIS Combination –Take the worst of FIP/SIP. Likely the wrong way to use SIP. –If FIP/SIP yields Yellow, then use FIS. FIS acts as a “tie breaker.” Icing/turbulence/thunderstorm Combination –Use worst case.
