## Aviation Weather Data Reporting

***Present:***  Collection is primarily ground based data compiled into weather forecasts
***Future:***  Real time weather data, measured in flight, including ascent and descent
- _How do we get there in Alaska ?_

## Advanced Aviation Weather Data Reporting 

- Using airborne sensors to improve weather products for all users
- Using airborne sensors for near real time delivery of weather data
- Weather data collection along airways, including ascent and descent
- Using ADS-B UAT Data Link to communicate to the NWS (National Weather Service)
- Uplink NWS Weather data to the NAS (National Airspace System)

## FIRST – some definitions...

_**ADS-B**_
_**A**_**utomatic ... It’s always on **
_**D**_**ependant ... Depends on GNSS for position information**
_**S**_**urveillance ... “Radar-Like” surveillance services**
_**B**_**roadcast ... Continuously broadcasts aircraft position and data **
_**UAT**_
_**U**_**niversal **
_**A**_**ccess **
_**T**_**ransceiver  ...  A bi-directional data link that has a broad frequency band available for data transmission. **
- (UAT is one of two data links FAA selected for deployment in the NAS.)** **

## TAMDAR

- _T_ – Tropospheric
- _A_- Airborne
- _M_- Meteorological
- _D_- Data
- _A_- Acquisition
- _R_- Reporting
- 	TAMDAR is a patented technology by AirDat, LLC that enables aviation platform real time weather data collection

## Experience of Past Success 

- Our Alaska Team consist of UAA, ADS-B Technologies, the Air Carriers Association, FAA, and others who individually and organizationally, were instrumental in development and successful deployment of the FAA Capstone program.

## Aviation Weather Tomorrow 

_**Using UAT ADS-B & TAMDAR**_
- NEXRAD
- METAR
- TAF
- Plus actual aloft measured data including:
- TURBULENCE
- ICING
- PIREPS
- AIREPS
- And much more......

## Weather Data in the Future using ADS-B / UAT & TAMDAR

- Current data  vs. Current forecast
- Continuing improvement in NWS Weather model – locally and downstream
- More usable data
- Areas not covered by other systems
- 3D products enabled real time to the flight deck

## Where we go from here

-  Developmental System
- TAMDAR via UAT ADS-B equipped aircraft
- Enables reduced weight using UAT ADS-B compared to built-in GPS
- Prince William Sound initial deployment
- Scheduled air carriers provide actual route and elevations sensor platform – at minimal additional cost

## How we get there

- Joint effort involving stakeholders
- Government
- FAA
- NWS
- NASA
- Industry
- Air Carriers
- Avionics
- Integrators
- Academia
- UAA
- CGAR

## Intent of coupling ADS-B & TAMDAR

- Initial Target:
- Bring real time measured weather data to NWS
- Subsequent Targets:
- Bring real time NWS weather to aircraft
- Incorporate this technology into NAS

## First Steps ADS-B TAMDAR

- Fund UAA for research and development of a weather data collection and distribution system
- Fund UAA to host and conduct stakeholder workgroup meetings
- Develop and Publish a comprehensive initial operations plan
- Fund the certification and installation in UAA research aircraft

## Next Steps

- Develop AML (multiple STCs for affected aircraft platforms)
- Equip commercial scheduled aircraft
- Begin data gathering using ADS-B/TAMDAR
- Begin using data to validate and improve weather reporting/forecasting
- Validate operational data value to industry
- Establish a MOPS for NAS Implementation
