What is S.E.T.?

• History SOAR/SET
• Spacing Efficiency Tool (SET) a tool to measure
  airport arrival efficiency
• Automation tool that measures distance between
  subsequent arrivals on final approach and
  compares actual to required separation
• Takes into account aircraft type and where
  authorized, runway-specific 2.5 mile separation

4
Goals and Objectives

• To provide a timely and reliable source of
  efficiency metrics to the Air Traffic Control
  System Command Center (ATCSCC) and other ATO
  lines of businesses
• To provide end users with a tool that provides a
  near real time snapshot of airport throughput
• Improved air traffic facilities situational
  awareness

5
Evaluate Efficiency

• By providing near real-time information useful in
  evaluating efficiency at a core airport
• SET Numbers are data points for additional level
  of focus
• Tool is not intended to assign a grade
• Still in the process of analyzing interactions
  between data elements on the SET Board
• Increased focus on spacing on final is expected
  to decrease excess spacing between aircraft,
  resulting in increased capacity and efficiency

SET Calculation vs. SET Index

• SET calculation represents the amount of spacing
  over and above what was required between two
  given aircraft on final. The user never sees the
  S.E.T. Score.
• SET Index is an average of all SET calculations
  registered by aircraft at that airport during the
  analyzed period and within the selected SET Zone.
  The SET Index is what appears throughout SET.

How Efficient was the Operation?

• SET index by itself doesnt tell the whole story
• Also need to consider Average Minutes Flown (time
  to airport), at a minimum
• Example an airport has a SET index of .86 and
  31 out of 32 aircraft were calculated. While
  seeming highly efficient at face value, average
  minutes flown was 29.24 because the airport was
  in and out of holding. Looking at both numbers
  puts more perspective on the operation at the
  airport during that time period

12
Access to SET

• Terminal Service Area Directors
• Managers of Tactical Operations (MTOs)
• Terminal Air Traffic Facility Managers ((DATM,
  ATM, OM) TMO)
• Terminal Traffic Management Officers (TMOs)
• Can be restricted by individual or area
• Note ELMS Training completion prior to access
• .

13
Current Status

• SET Sponsor Air Traffic Control System Command
  Center development in coordination with Terminal
• Uses data from the National Offload Program
• Additional airports continue to be adapted and
  requirements still evolving
• Scheduled for field facilities deployment
