FLL Background• FLL is representative of a high impact airport with a mix of

major airlines for demonstration of DCL benefits.• FLL is ranked 19th nationwide in on-time performance.• Data Comm program has FLL SME expertise available.

FLL Modeling Assumptions• Simulations created using Total Airport and Airspace Modeler• Model includes En Route, TRACON and surface operations

– ETMS city pair routing– FLL terminal airspace SID/STAR procedures– Terminal airspace spacing, vectoring, separation, wake turbulence– Airport gate usage, taxi, departure line up queuing at runway threshold– East and West flow operations examined

• Traffic: 90th percentile day by operations (FY10)• Wx: FLL north departures impacted by simulated reroutes for

afternoon convective weather, en route capacity is not constrained • Voice reroute clearance time is randomly assigned by TAAM

– 2.5 to 4.5 minutes per aircraft, includes clearance and pilot read back– Verified per SME input and Data Comm Benefits Team

• Data Comm reroute clearance time is randomly assigned by TAAM– 10 to 20 seconds per equipped aircraft– Assigned at the gate

Annual FLL Airport Data Comm Impact:Annual FLL Airport Data Comm Impact: • Estimates do not include 17 days of mixed runway configurations • Savings for 80 days using DCL Service with 2016 Equipage Scenario A is estimated at 32,122 minutes 32,122 minutes.• Savings for 80 days using DCL Service with 2016 Equipage Scenario B is estimated at 53,049 minutes 53,049 minutes..

Discussion

• Modeling DCL services shows significant savings.• The higher the equipage, the higher the savings.• Non-Equipped aircraft will receive a residual benefit as

a result of the equipped aircraft.• Increased traffic levels will result in higher savings.• Next Steps

– FLL Mixed Runway Simulations– Access Arrival Benefits– Enhanced Benefits Methodology– Expand Analysis to other Airports
