Runwayoccupancy timeand ground taxi
Corridor based onG N & C performance
Required for:- Time delay in comm.- Wake vortex corridor
More Operations per Runway
Gap due to inefficientmetering & sequencing
Buffer due to wake vortex uncertainties
Buffer due to impreciseflight management
*
More Runways per Airport

LVLASO Objective:
Safety achieve clear-weather runway and taxiway capacity for surface low visibility, night or unfamiliar conditions. Accomplish through ROTO, T-NASA, and DROM technologies
T-NASA utilizes a combination of head up simulated vision display and moving perspective airfield map. It gets information on the cleared taxi route via datalink from the controller. Other airport surface traffic locations and conflict detection is provided by radar and surface automation plus displays for the controller

Traffic Management Advisor (TMA)
• Traffic Management tool to provide arrival traffic flow visualization and scheduling
• Assists controllers in balancing arrival demand with airport capacity while minimizing delays
• Develops a safe and efficient schedule for arrival traffic to maximize airport capacity
• Increases airport capacity, reduces arrival delays, and reduces controller workload by advising enroute sector controllers of the optimized schedule

Approach: Provide recommended runway assignments and sequences to the air traffic controller.Balance use of runways based upon prediction of aircraft runway-crossing times, using accurate aircraft & wind models.
Benefits: Maximizing landing throughput reduces delays and fuel usage, thereby reducing flight costs and aircraft emissions.
Status: Operational at Dallas-Fort Worth airport and being implemented by FAA at 10 other airports.
Objective: Assist the air traffic controller in maximizing arrival traffic flow to multiple runways.

Surface Movement Advisor (SMA)
The Surface Movement Advisor (SMA) is a joint Federal Aviation Administration (FAA) and National Aeronautics and Space Administration (NASA) project to help current airport facilities operate more efficiently. The SMA system integrates the airline schedules, gate information, flight plans, radar feeds and runway configuration (departure split and landing direction). This integrated information is then re-transmitted over the network system and shared between the key players at the airport: Ramp Operators, Airport Managers, The Airline Operators, FAA Controllers and Supervisors
Goals:• Provide Gate Resource Optimization• Balance Taxi Departure Loads• Reduce Voice Radio Traffic• Improve Gate Rescheduling• Facilitate Airport Operations Analysis• Improve Crew Scheduling

Objectives:• Develop an initial set of cross-comparable economic benefits data for each of the AATT decision
support tools (DST) for use in project decision making
Approach:• Common input data sets, assessment ground-rules, and economic conversion factors were
provided to all the benefit assessment teams to maximize comparability across the various DST assessments
• Assessment methodologies and tools were developed which addressed the specific benefit mechanisms of the AATT DST’s
• 1996 and 2015 traffic demand levels were analyzed and benefits provided for both years• Benefits assessed at 43 airports as applicable
