What illuminates parking areas at an aerodrome?

The illumination of parking areas at an aerodrome is primarily done using blue lights. This color is used specifically to denote the locations of aircraft parking spots, ensuring that pilots can easily identify these areas both during daylight and at nighttime. The use of distinctive colors helps in avoiding confusion with other operational areas, which is critical for maintaining safety on the airfield.

In contrast, other colors have specific uses in aviation lighting. For instance, green lights typically denote runways or indicate the approach direction to a runway. Red lights often signify that an area is restricted or contaminated, while yellow lights are usually associated with taxiway markings or to indicate caution in certain zones. Understanding the color coding used in aviation lighting is essential for pilots, as it aids in navigation and enhances safety during ground operations.
