How is the height of a control tower typically indicated?

The height of a control tower is typically indicated by a clear and concise marking that is often located right under the control tower. This marking is important for aircraft pilots and air traffic control personnel, as it allows for quick and easy identification of the tower's height. Such visual indicators are crucial for ensuring safe flight operations, as they help pilots understand their vertical positioning in relation to the control tower during takeoffs and landings.

While the color of the tower might provide visibility, it does not give specific height information. Similarly, although markings on the building’s side may indicate height, they are not standardized in the same way as the dedicated markings below the tower. Radar readings do not convey the physical height of the structure; instead, they are used for tracking aircraft positions and movements. Thus, the most straightforward and useful method for indicating the height of a control tower involves the markings beneath it.
