AVTECH Sweden AB (publ) announced a three-year contract extension with Dallas, Texas-based Southwest Airlines® for the Aventus Enroute and Descent Winds service. The service agreement is extended until the end of June 2026 with an expected contract value between SEK 38 million and SEK 52 Million, dependent on USD exchange rate. The Aventus Enroute and Descent Winds services, together also known as Aventus Full-flight Winds, provides highly accurate and tailored wind and temperature information in-flight to Southwest Airline’s aircraft.

This supports improved flight execution, increased situational awareness, and reduced workload for the pilots. The optimized descent winds enable improved aircraft automation while reducing the CO2 footprint and flight crew workload for the descent phase of each flight. Through optimization of the flight path, AVTECH estimates the service to save up to 84,000 metric tons of CO2e yearly in Southwest’s operation.

This is a part of the airline’s initiative to reduce its environmental impact. Utilization of Aventus optimal wind data additionally positions Southwest for the continued expansion of NextGen initiatives.
