What color is the solid line that denotes tail wingtip clearance?

The solid line that denotes tail wingtip clearance is colored white. This color coding is essential for airside operations as it helps operators visually identify safe distances from aircraft. The white line indicates the area that should be kept clear to ensure that the wings and tail of an aircraft do not interfere with vehicles or equipment moving in that vicinity. This is particularly important in preventing damage to the aircraft or vehicles and maintaining safety in high-traffic areas like the airside of an airport.

Other colors like red, green, and yellow are used for different purposes on airport grounds, which have specific meanings regarding safety zones, operational limits, or other indications. Understanding the significance of these colors is crucial for anyone operating vehicles in the airside environment to ensure compliance with regulations and safe conduct around aircraft.
