ATD-2 Surface Scheduling and Metering Concept

This presentation describes the concept of ATD-2 tactical surface scheduling and metering. The concept is composed of several elements, including data exchange and integration; surface modeling; surface scheduling; and surface metering. The presentation explains each of the elements. Surface metering is implemented to balance demand and capacity When surface metering is on, target times from surface scheduler areconverted to advisories for throttling demand Through the scheduling process, flights with CTOTs will not get addedmetering delay (avoids potential for double delay) Carriers can designate certain flights as exempt from metering holds Demand throttle in Phase 1 at CLT is through advisories sent to rampcontrollers for pushback instructions to the flight deck Push now Hold for an advised period of time (in minutes) Principles of surface metering can be more generally applied to otherairports in the NAS to throttle demand via spot-release times (TMATs Strong focus on optimal use of airport resources Flexibility enables stakeholders to vary the amount of delay theywould like transferred to gate Addresses practical aspects of executing surface metering in aturbulent real world environment Algorithms designed for both short term demand/capacityimbalances (banks) or sustained metering situations Leverage automation to enable surface metering capability withoutrequiring additional positions Represents first step in Tactical/Strategic fusion Provides longer look-ahead calculations to enable analysis ofstrategic surface metering potential usag
