TSAS extend the metering capability into the terminal area by providing tools to
terminal ATC and TMU for time-based merging, sequencing and spacing.
MAP OF DEPLOYMENT
Current guidelines for en route controllers are to deliver flights
to their meter fixes within +/- 60 seconds of their STAs. TSAS requires improved delivery
accuracy (+/-30seconds) to produce the desired flight efficiency gains.
GIM-S capabilities enable improved meter fix delivery accuracy
Extended Metering allows for en route delay to be absorbed over more
sectors and greater distances.
Speed advisories help controllers deliver flights to meter fixes
with greater precision
Increases the use of Performance Based Navigation (PBN) to improve
Supports Optimization of Airspace and Procedures in the Metroplex
(OAPM) redesign goals
Supports the future use of Flight Deck-Interval Management (FIM)
Extends use of time-based metering from the en route domain to the
terminal domain and runway, leveraging the FAA’s investment in TBFM
