## Weather Concept Philosophy

**Our charge is NOT about the weather ...**
**	****	****Rather, it is about the**

***Identification and effective use***
***of weather information***
***(and supporting capabilities)***
***to mitigate weather impacts******	******   on NGATS operations***

## Weather Concept Scope/Approach

- Scope
- 2025 concepts for Weather Support (future vision)
- Starting point for inter-IPT discussions
- First step in NGATS weather functional analysis
- Approach
- Analyzed NGATS 2025 Operating Principles and Key Capabilities
- Identified Weather Implications/Impacts
- Established resulting Operating Principles for NGATS Weather Support Concepts
- Developed Weather Concept Details
- To Follow...
- Transition “Road Map”
- Transition plan for Weather Support - current NAS to 2025 Concept
- Complementary products:
- Weather System Requirements
- Supporting R&D Requirements

## Weather Implications/Impacts AMDAR Data Access

- Section 2.3 (Performance-Based Services)
- “... enables a definition of service tiers and allows the government to move from equipment-based regulations to performance-based regulations.”
- 2.3.1:  Aircraft are capable of receiving and transmitting weather information
- 2.3.2:  Weather sensors included in Performance-Based Services
- “... At a minimum, in addition to accurately providing its 4-D geospatial position, aircraft provide in situ winds, temperature, relative humidity, turbulence and icing information.  Aircraft may also measure non-weather phenomena (e.g., volcanic ash), utilize forward or down looking remote weather sensors, and carry dosimeters to measure the radiation environment which is affected by space weather activity.”

## Weather Concept Operating Principles AMDAR Data Access

- Operating principles
- Derived from the analysis of the implications/impacts of weather from the NGATS 2025 Concept
- Grouped into five (5) categories:
- Policy and Organization
- Data Collection and Access
- Products and Decision Oriented Tools
- Integration and Procedures
- Enhanced Aircraft Capabilities

## Data Collection and Access AMDAR Data Access

- Section 3.2.d:  Aircraft “Performance-Based Service” includes data link capability for:
- Accessing and processing in-flight updates to NGATS weather products
- Transmitting and receiving aircraft weather data generated through on-board automation such as the Meteorological Data collection and Reporting System (MDCRS) or Tropospheric Airborne Meteorological Data Reporting (TAMDAR) type systems.
- Note:  UAS platforms are used to gather such in-flight data.

## Summary

- Under NGATS (Section 2.3.2):
-    “Fully capable aircraft have a standardized set of weather sensors/algorithms to provide weather data to other users directly and via the [NGATS] 4-D Weather.  Weather data from aircraft are valuable inputs to the [NGATS] 4-D Weather for providing advice and warning to nearby aircraft, and for providing input and verification for weather forecast products. ...”
