## (T-NASA) Displays

**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

**PI:**Len Tobias, NASA Ames Research Center

## Passive Final Approach Spacing Tool (pFAST)

**	****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**

##  Benefit Assessment of NASA ATC Tools

**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

## Distributed Air Ground Traffic Management:  AGIE Study

**Approach**
**Assist flight crews and controllers with shifting roles and responsibilities **
**Examine human performance parameters for flight crews and controllers in a full-mission simulation environment**
**Impact**
**Airspace factors in shared separation may have an impact upon controller and flight crew conflict detection  **
**Ability to contact other flight crews in a free flight environment may be important for assessing conflict probability**

**Investigate flight crew and air traffic controller procedures and tools **
**for shared separation tasks**
