Airbus Limits Takeoffs in Cold Weather for Some Pratt & Whitney-Powered Aircraft
Airbus is restricting operations for some aircraft in cold weather conditions. The measures affect single-aisle aircraft equipped with Pratt & Whitney PW1100 GTF engines. The company has notified airlines of updated procedures established for pre-takeoff maneuvers in scenarios with freezing fog and visibility of less than 150 meters.
A spokesperson for the European manufacturer confirmed that the adjustments aim to reinforce safety during critical phases at airports affected by ice. They added that there is ongoing communication with operators and that Pratt & Whitney is working on a technical solution. The US-based firm did not provide immediate comment.
Impact on Airlines and Operations
The restrictions apply to A320 family models powered by GTF engines. Aerotelegraph reported that Air Astana had to delay several departures of aircraft with this propulsion system due to the presence of freezing fog. The specialized publication was the first to report on the measure.

Risks Associated with In-Flight Ice
Ice formation can alter airflow over the wings, generate additional drag, or reduce thrust capability. These effects have been factors in several accidents over time, which is why the industry maintains strict protocols to mitigate any risk.
GTF Engine Context
Pratt & Whitney, a unit of RTX, has faced previous problems with contaminated metal dust in components of its GTF engines. This issue forced various operators to temporarily ground part of their A320 fleets while affected parts were replaced.
The company continues working to reduce repair delays and advance the certification of an improved engine version, aiming to normalize the performance of the product line and return operational capacity to airlines.
