• STEP 3 – Arrival ManagementSTEP 3 – Arrival Management

• ACTION:ACTION:

– SDSS Assigns an arrival runway and arrival slot timeSDSS Assigns an arrival runway and arrival slot time


– SDSS shows arrival runway and assigned time on timelineSDSS shows arrival runway and assigned time on timeline

– SDSS recalculates On, In times as neededSDSS recalculates On, In times as needed


– Assignment of Arrival Runway considers parking location on the airfield Assignment of Arrival Runway considers parking location on the airfield to minimize taxi time and surface congestionto minimize taxi time and surface congestion

• STEP 5 – Parking Gate ConflictSTEP 5 – Parking Gate Conflict

• ACTION: SDSS Alerts Ramp Tower to Potential Parking Gate ConflictACTION: SDSS Alerts Ramp Tower to Potential Parking Gate Conflict

• SYSTEM RESPONSE / VISUALIZATION:SYSTEM RESPONSE / VISUALIZATION:– SDSS In time prediction shows that the arriving flight will get to the parking gate SDSS In time prediction shows that the arriving flight will get to the parking gate

before the current flight in the gate pushes backbefore the current flight in the gate pushes back– The SDSS Ramp Position alerts the Ramp Controller and Requests a Decision The SDSS Ramp Position alerts the Ramp Controller and Requests a Decision

from the Ramp Controllerfrom the Ramp Controller• To either change the parking gate or indicate that the arriving flight should be To either change the parking gate or indicate that the arriving flight should be

held out of the rampheld out of the ramp– The Ramp Controller decides the flight should be held out of the rampThe Ramp Controller decides the flight should be held out of the ramp– The ATC Tower Controller is notified of the need to hold the flight out on CARTSThe ATC Tower Controller is notified of the need to hold the flight out on CARTS

• BenefitBenefit– The Tower knows that the flight has no gate before it is blocking other flightsThe Tower knows that the flight has no gate before it is blocking other flights
