What is a good rule of thumb regarding taxi speed?

A good rule of thumb regarding taxi speed is no faster than a brisk walk. This guideline ensures that pilots maintain a safe and controlled speed while taxiing. Taxiing is performed in a congested environment where other aircraft, vehicles, and personnel may be present. By keeping the speed to that of a brisk walk, pilots can react promptly to any unforeseen circumstances, such as another aircraft crossing their path or sudden instructions from air traffic control.

Choosing a speed that aligns with the brisk walking pace allows for better control of the aircraft, enhancing situational awareness and safety. It also minimizes the risk of damage to the aircraft or other ground personnel that may be in the vicinity.

Other speeds, such as faster than a brisk walk, would increase the risk of accidents and reduce the pilot's ability to react quickly during taxi operations. Therefore, adhering to this guideline is essential for ensuring safety on the ground.
