- Airfield Lighting Sustainability Study
Burns & McDonnell inspected, evaluated and studied the airfield lighting system, including field components and those within two electrical vaults and the control tower. The project team reviewed existing airport plans, conducted site surveys, analyzed survey information and photos, and discussed plans with airport and Federal Aviation Administration personnel. The main objective of the study was to review all airfield electrical components for condition, maintenance/replacement needs and to identify potential projects that could provide electrical efficiency, reliability and reduced maintenance.
LED lighting options were evaluated for taxiway lighting and wind cones. Over the winter, a few LED taxiway lights were installed and evaluated for performance in cold weather conditions. A financial evaluation of the rate of return on investment and physical damage probabilities during plowing operations was conducted. With a successful test of the LED taxiway lighting and a favorable financial review, the airport will consider LED for future taxiway lighting projects. The airport also decided to replace all existing incandescent wind cones with LED types. These projects will have a significant impact on electrical use.
As the electrical load for taxiway lighting and wind cones is reduced, we will modify the Airfield Constant Current Regulators by replacing them with smaller rated units or change their settings to improve performance and efficiency and reduce maintenance. Future projects, identified in our report, include apron lighting improvements that will replace old fixtures with new ones with electronic ballasts, new control systems that allow circuit isolation/control, and revised layouts to reduce the number of fixtures needed to light the apron areas.
A new airfield lighting control system was also recommended to isolate circuits during various weather conditions so the entire airfield lighting system would not be on at all times. These improved control capabilities also increase efficiency and reliability.
