The International Air Transport Association (IATA) has launched its ‘Turbulence Aware Data’ resource to help airlines worldwide avoid turbulence when planning routes tactically in flight.
Turbulence Aware augments an airline’s ability to forecast and avoid turbulence by pooling and sharing (in real time) turbulence data generated by participating airlines.
Airlines now rely upon pilot reports and weather advisories to mitigate the impact of turbulence on their operations, the IATA noted.
These tools - while effective - have limitations due to the fragmentation of the data sources, inconsistencies in the level and quality of information available, and the locational imprecision and the subjectivity of the observations. For example, there is no standardised scale for the severity of turbulence that a pilot may report other than a light, moderate or severe scale, which becomes very subjective among different-sized aircraft and pilot experience.
Turbulence Aware improves on the industry’s capabilities by collecting data from multiple contributing airlines, followed by a rigorous quality control. Then the data is consolidated into a single, anonymised, objective source database which is accessible to participants. Turbulence Aware data is turned into actionable information when fed into an airline’s dispatch or airborne alerting systems. The result is the first global, real-time, detailed and objective information for pilots and operations professionals to manage turbulence.
IATA’s Director General and CEO Alexandre de Juniac said: “Turbulence Aware is a great example of the potential for digital transformation in the airline industry. The airline industry has always co-operated on safety - its number one priority. Big data is now turbocharging what we can achieve. In the case of Turbulence Aware, the more precise forecasting of turbulence will provide a real improvement for passengers, whose journeys will be even safer and more comfortable.”
The challenge of managing turbulence is expected to grow as climate change continues to impact weather patterns. This has implications for both safety and efficiency of flight.
Turbulence is the leading cause of injuries to passengers and crew in non-fatal accidents, according to the Federal Aviation Authority (FAA).
As we progress to having accurate turbulence data available at all flight levels, pilots will be able to make much more informed decisions about higher flight levels with smoother air. Being able to climb to these altitudes will result in a more optimal fuel burn, which will ultimately lead to reduced CO2 emissions.
Turbulence Aware is already generating significant interest among airlines. Delta Air Lines, United Airlines and Aer Lingus have signed contracts; Delta is already contributing their data to the programme, IATA noted.
“IATA’s collaborative approach to creating Turbulence Aware with open source data means that airlines will have access to data to better mitigate turbulence. Using Turbulence Aware in conjunction with Delta’s proprietary Flight Weather Viewer app is expected to build on the significant reductions we’ve seen already to both turbulence-related crew injuries and carbon emissions year-over-year,” said Jim Graham, Delta’s senior vice president (Flight Operations).
The first operational version of the platform will be developed by the end of this month. Operational trials will run throughout 2019, with ongoing feedback collection from participating airlines. The final product will be launched in early 2020, IATA said.
