Working with AVTECH
The Met Office and AVTECH first collaborated back in 2007 on a SESAR project which required accurate wind nowcasting to support Continuous Descent Operations.
Following this, AVTECH and the Met Office worked together to commercialise the descent winds offering – providing high resolution gridded weather model data cut-outs measuring 600kmx600km, across 12 vertical levels, for around 120 airports.
The downside of this solution was that the Met Office was shipping large volumes of data to AVTECH’s datacentre – the vast majority of which were unused. The demand from airline users to cover more airports was also increasing. A solution that worked at scale, providing only the relevant information required for the aircraft uplink was needed.
A few years later, the Met Office developed the capability to provide 4D trajectory data on demand so that AVTECH could make requests in real-time for data from the Met Office’s global model. This could be used for the descent, cruise and climb phases of operation for any global airport. This formed the basis of the capability AVTECH access today that has led to the success of the Aventus product. In 2017, the Met Office enhanced the 4D trajectory query further – allowing a “corridor” of weather forecast data to be extracted from the weather model leading to the integration of gridded aviation hazard data, e.g. turbulence into the AVTECH ProFlight product range.
