OWS-8 Aviation

Thread Architect:
Nadine Alameh, Ph.D.
OGC

The Aviation Thread of OWS-8 builds on the Aeronautical Information Management (AIM) and Aviation threads of OWS-6 and OWS-7, and seeks to further develop and demonstrate the use of the Aeronautical Information Exchange Model (AIXM) and the Weather Information Exchange Model (WXXM) in an OGC Web Services environment.

The US Federal Aviation Administration (FAA) and EUROCONTROL have developed AIXM as a global standard for the representation and exchange of aeronautical information. AIXM was developed using the OGC Geography Markup Language (GML) tailored to the specific requirements for the representation of aeronautical objects, including the temporality feature that allows for time dependent changes affecting AIXM features. The overall objectives of the FAA and EUROCONTROL are to use AIXM as a basis for modernizing their aeronautical information procedures and transitioning to a net-centric, global aeronautical management capability. More specifically, AIXM is being used in the net-centric System Wide Information Management (SWIM)-related components of the US NextGen and European Union (EU)’s SESAR programs.

WXXM is the proposed standard for the exchange of aeronautical weather information in the context of a net-centric and global interoperable Air Transport System (ATS). It is currently under development by FAA and EUROCONTROL in support of the NextGen and SESAR programs. WXXM also uses GML tailored to the specific requirements of aeronautical meteorology and is based on the OGC Observation and Measurement Model. WXXM development is harmonized and coordinated with the World Meteorological Organization (WMO), the organization traditionally responsible for standards in meteorology.

Building on previous initiatives...

OWS-8 Aviation builds on the outcomes of three previous initiatives. For this reason, the demonstrations will get technical at times. This is because after 3 initiatives, we’re truly getting into the unescapable nitty gritty details of the work. Click an area on diagram to launch prior demonstration in new browser tab or window.

AIXM - WXXM

However, the work is still centered around the validation and advancements of two information exchange models used in Aviation: AIXM (below) and WXXM (next page).

AIXM (diagram below): based on GML, representing features like runways, taxiways, navigational aids, airspaces and even individual lights on a runway.

Weather Information Exchange Model (WXXM)

WXXM (diagram below): based on GML and O&M, for weather information like TAFs for visibility, humidity, thunderstorms, volcanic ash, etc.

Both AIXM and WXXM models are challenging in handling temporality – tracking and using time-based and time-sensitive information.

OWS-8 Aviation Scenario

  • Flight going from Tallin (Estonia) to Hawaii via Chicago.

OWS-8 Aviation Scenario (continued)

  • The architecture developed here can aid in the communications and response to sudden disasters, such as the Pacific tsunami event caused by the earthquake in Japan, March 2011.
WXXM Diagram

 

March 11, 2011: This was the day of a devastating earthquake in Japan, resulting in a tsunami warning in Hawaii. Pilots and dispatchers would get the right information at the right time using our architecture, to avoid landing on a flooded runway.
