What action should be taken if the lights on AFLCS are burnt out?

The appropriate course of action when the lights on AFLCS (Automatic Flight Landing Control System) are burnt out is to contact Public Works for maintenance. This option is correct because maintaining and repairing lighting systems generally falls under the purview of the maintenance team or facility management personnel. They have the expertise, tools, and resources necessary to address electrical and lighting issues safely and effectively.

In situations like this, calling maintenance ensures that the repair is conducted in compliance with safety standards and regulations. This approach minimizes the risk of accidents or additional damage that could occur from an untrained individual attempting to fix the issue on their own.

Other options, while they might seem like potential responses, are not suitable for this specific situation. Emergency landing protocols would typically only be invoked in a life-threatening situation or when the aircraft is in immediate danger, which does not apply to burnt-out lights alone. Resetting the modem is irrelevant to the lighting issue since it does not address the physical problem of non-operational lights. Although replacing the lights on site might sound feasible, this action should only be carried out by qualified personnel to ensure compliance with safety regulations and to avoid further complications.
