Lighting System Control Points. At airfields and heliports there normally will be two
points of control for the lighting system. The primary point of control will be in the operations
room of the control tower. The alternate (secondary) point of control will be located in the
equipment vault unless specifically directed or approved location elsewhere.
5.15.3
Maintenance Responsibility. The responsibility for maintaining lighting control panels
varies at DOD facilities such as the Directorate of Public Works (DPW), Ground Electronics
Group, or Base Civil Engineering (BCE), either using in-house personnel or by contract.
