In icy runway conditions, what is the maximum allowable wind during taxi?

In icy runway conditions, the choice of a maximum allowable wind during taxi is significant for maintaining safety. The correct answer reflects an understanding of both aircraft performance and environmental factors impacting ground operations.

Wind can affect an aircraft's control and stability, especially on icy surfaces where the risk of skidding or losing directional control is heightened. A maximum allowable wind of 5 knots during taxi provides a balance that minimizes these risks while allowing for safe maneuverability.

This limit considers the difficulty pilots may face in maintaining control at higher wind speeds on slippery surfaces. At 5 knots, the wind may assist in maintaining aircraft control while still allowing for effective response to any directional changes needed during taxiing. Ensuring that wind speeds are within this limit helps preserve safety in icy conditions, minimizing the chances of losing control due to the combination of wind and reduced friction on the runway surface. Other options suggest tolerances that could potentially compromise safety, particularly in challenging runway conditions.
