“…It has the ability to efficiently generate Scheduled Times of Arrival (STA) of each aircraft to a Constraint Satisfaction Point (CSP), such as Meter Point (MP), MFX, and Runway Threshold (THD). This tool has been shown to reduce airborne holding, in-trail restrictions, and departure delays while increasing airport throughput and is currently operational at all 20 domestic Centers, select TRACONs and towers [16].…”

This paper introduces NASA's Integrated Demand Management (IDM) concept and presents the results from an early proof-of-concept evaluation and an exploratory experiment. The initial development of the IDM concept was focused on integrating two systems-i.e. the FAA's newly deployed Traffic Flow Management System (TFMS) tool called the Collaborative Trajectory Options Program (CTOP) and the Time-Based Flow Management (TBFM) system with Extended Metering (XM) capabilities-to manage projected heavy traffic demand into a capacity-constrained airport. A human-in-the-loop (HITL) simulation experiment was conducted to demonstrate the feasibility of the initial IDM concept by adapting it to an arrival traffic problem at Newark Liberty International Airport (EWR) during clear weather conditions. In this study, the CTOP was utilized to strategically plan the arrival traffic demand by controlling takeoff times of both short-and long-haul flights (long-hauls specify aircraft outside TBFM regions and short-hauls specify aircraft within TBFM regions) in a way that results in equitable delays among the groups. Such strategic planning decreases airborne and ground delay within TBFM by delivering manageable long-haul traffic demand while reserving sufficient slots in the overhead streams for the short-haul departures. A manageable traffic demand ensures the TBFM scheduler does not assign more airborne delay than a particular airspace is capable of absorbing. TBFM uses its time-based metering capabilities to deliver the desirable throughput by tactically coordinating and scheduling the long-haul flights and short-haul departures. Additional research was performed to explore the use of Required Time of Arrival (RTA) capabilities as a potential control mechanism to improve the arrival time accuracy of scheduled long-haul traffic. Results indicated that both short-and long-haul flights received similar ground delays. In addition, there was a noticeable reduction in the total amount of excessive, unanticipated ground delays, i.e. delays that are frequently imposed on the shorthaul flight in current day operations due to saturation in the overhead stream, commonly referred to as 'double penalty.' Furthermore, the concept achieved the target throughput while minimizing the expected cost associated with overall delays in arrival traffic. Assessment of the RTA capabilities showed that there was indeed improvement of the scheduled entry times into TBFM regions by using RTA capabilities. However, with respect to reduction in delays incurred within TBFM, there was no observable benefit of improving the precision of entry times for long-haul flights.

“…This tactical departure scheduler leverages the TBFM / Integrated Departure Arrival Capability (IDAC) Integrated Departure Scheduling Tool (IDST) for APREQ/CFR coordination between ATC Tower and Center. Like IDST, the STBO Client will allow users to view slots in the overhead stream on a runway timeline and submit electronic requests for release times for flights subject to APREQ restrictions through IDAC-enabled Centers [4]. STBO Client users will also have the added ability to manually input release times obtained through current day CFR procedures into the STBO Client and release times electronically coordinated with the Center while viewing other TMIs for a flight, such as an EDCT.…”

NASA is collaborating with the Federal Aviation Administration (FAA) and aviation industry partners to develop and demonstrate new concepts and technologies for Integrated Arrival, Departure, and Surface (IADS) traffic management capabilities under the Airspace Technology Demonstration 2 (ATD-2) project. One of the goals of the IADS capabilities in the ATD-2 project is to increase predictability and throughput of airspace operations by improving Traffic Management Initiative (TMI) compliance. This paper focuses on the Approval Request (APREQ) procedures developed for the ATD-2 project between the Air Traffic Control (ATC) Tower at Charlotte Douglas International Airport and Washington Center. In March 2017, NASA conducted a Human-in-the-Loop (HITL) simulation to evaluate the operational procedures and information requirements for the APREQ procedures in the ATD-2 IADS system between ATC Tower and Center. The findings from the HITL are used to compare ATD-2 APREQ procedures with information about current day APREQ procedures.

“…Initial research into integrating runway arrival and departure operations has also been conducted generating preliminary concepts and algorithms [13][14][15]. In this paper, we describe a research activity in support of a concept developed by NASA (ATD-2) which attempts to integrate departure and arrival operations in a metroplex, with an emphasis on integrating departure operations [16][17]. The operations are integrated from the release from the gate on the airport surface, to the takeoff from the runway, to the crossing of departure fixes and the merging into the overhead traffic stream.…”

Integrated schedules of arrival, departure and surface operations need to maintain a certain level of robustness in order to accommodate uncertainties stemming from the operations and the environment. This robustness is needed to maintain high throughput and conformance to the schedule. One method to achieve such robustness is for the schedule to allow for queue and delay buffers, particularly at the main choke resources of the system, such as runways. In this paper, a method based on identifying throughput saturation using analysis of historical data is used for determining the appropriate size of the buffers. The analyses are applied to departure operations of Charlotte International Airport and insights are drawn on the existence historically of throughput saturation of runways and the sensitivity of the buffer sizes to a number of modeling parameters and airport conditions.
