INF11.1 — Enhanced Ground Weather Management System (GWMS) as local 4DWxCube

The Enhanced Ground Weather Management System (GWMS) is an evolution of the GWMS developed for the first time in SESAR 1. The Enhanced GWMS is compliant to specifications of the 4DWxCube instance in Aerodrome ATM MET CC. MET for Total Airport Management, which comprises the bulk of local MET information, is developed and integrated into GWMS as a SWIM service (METForTAM). This validates its general capability for the provision of both existing standard and future MET SWIM services dedicated to particular operational environments like Wake Turbulence Separations.

The provision of METForTAM by GWMS has been designed and validated to be SWIM Technical Infrastructure Yellow Profile compliant using AMQP1.0 messaging. This information service may be used to provide enhanced local MET information (e.g. METEO forecasts and observations) to a specific airport (airport operational centre, APOC).

The new capability Glide Wind Profile has also been developed to provide glide wind data into the GWMS using sources like Radar and Lidar sensors. The purpose of these observations is to enhance separation procedures based on the collected glide slope wind data.

These developed capabilities and information services aim to provide enhanced MET data capabilities, in order to improve the accuracy and timely delivery of certain Meteorological conditions at an airport. Specifically, supporting the airport operator and other local stakeholders and, in turn, airspace users to improve their situation awareness and decision making.

NOTE 1: SESAR recommends development of additional SWIM services centred around local MET capabilities and requirements, in addition to a long-term validation exercise to test handling several services at more than one airport to demonstrate the full capabilities of 4DWxCube. This would serve to demonstrate the benefits compared with currently available meteorological information and data provision.

NOTE 2: It should be noted that the implementation of new MET information services, including high resolution wind profiling, are not mandatory for deployment at all airports, but should be considered if there is an operational need for such enhancements.
