What are the key considerations for selecting the appropriate towing speed for an aircraft tug on a wet surface?

Selecting the appropriate towing speed for an aircraft tug on a wet surface requires careful consideration of several factors to ensure safe and controlled movement. The most critical factor is reducing the towing speed significantly compared to dry conditions. Wet surfaces reduce the friction between the tug's tires and the pavement, increasing the risk of skidding or loss of control. As a general guideline, reduce the towing speed by at least 50% on a wet surface. The specific type of pavement also plays a role. Smooth concrete surfaces tend to be more slippery than grooved asphalt surfaces. Adjust the towing speed accordingly, reducing it further on smoother surfaces. The weight of the aircraft being towed is another key consideration. Heavier aircraft require more braking distance, which is further increased on wet surfaces. Reduce the towing speed even further when towing heavier aircraft. The tug's tire condition is also important. Worn tires have less grip than new tires, especially on wet surfaces. Ensure that the tug's tires are properly inflated and have sufficient tread depth. Weather conditions, such as the intensity of the rain and the presence of standing water, should also be taken into account. Towing speed should be further reduced during heavy rain or when there is standing water on the pavement. The presence of ice or snow requires even more extreme caution and may necessitate the use of specialized towing equipment or delaying the operation altogether. Constant communication between the tug operator and any wing walkers or spotters is essential. The wing walkers can provide valuable feedback on the aircraft's movement and any potential hazards. Finally, always adhere to airport regulations and procedures regarding towing speed limits, which may be further restricted during wet weather conditions. Failure to consider these factors can lead to loss of control, collisions, and damage to the aircraft or tug.
