What kind of lighting system is activated by pilot control?

The Surface Movement Guidance and Control System (SMGCS) is a specific type of lighting system that can be activated by pilot control. This system consists of ground lighting and signage that aids pilots in navigating safely on the airport surface, especially in low visibility conditions. The pilot control aspect usually involves the activation of these lights through communication with air traffic control, ensuring that pilots can safely taxi to and from runways and gates.

High-intensity lights, taxiway edge lights, and runway visual range lights all serve specific functions but do not typically include pilot-activated controls as a common feature. High-intensity lights are often utilized for runway operations and may be controlled by air traffic rather than by pilot request. Taxiway edge lights provide guidance along taxiways but are generally not activated by pilots. Runway visual range lights give a measure of visibility for pilots but, like others, are not activated directly by pilots in the same manner as the SMGCS. Thus, SMGCS stands out as the correct answer due to its design and operational capability regarding pilot control.
