What is the maximum taxi speed in straight conditions on wet or contaminated surfaces?

The maximum taxi speed in straight conditions on wet or contaminated surfaces is set at 10 knots. This limit is established to ensure safety and control of the aircraft under conditions where traction may be compromised. Wet or contaminated surfaces can significantly affect braking and directional control, which is why maintaining a lower speed is crucial. By adhering to this speed limit, pilots can better manage the aircraft's performance on less-than-ideal surfaces and reduce the risk of accidents due to hydroplaning or loss of control.

Knowing this limit is essential for pilots to operate safely and effectively in varying weather conditions, ensuring that they always prioritize safety and operational integrity when taxiing on potentially slippery surfaces.
