Approach Lighting


Approach Lighting Systems - Research & Development

The purpose of this research is to determine if a more effective, cost efficient Approach Lighting Systems (ALS) can be developed to meet the increasing need at airports.

This effort includes:

  • Modifying and/or reducing the number of lights in a standard ALS configuration.
  • Evaluating new technology for use as ALS components. Configurations differing significantly from those presently in service, but offering advantages in economy and/or effectiveness.
  • The data will be used in developing a performance specification for an ALS having reduced Acquisition, Installation, and Maintenance costs while maintaining the visual cues necessary for safe operations.

Plan objectives:

  • Determine those devices and/or concepts most likely to provide significant enhancements to approach lighting systems.
  • Test Feasibility light bars using these devices and/or concepts. Field test the proposed approach lighting system.
  • New technologies such as, fiber optics, metal halide lamps, light emitting diodes, are being considered.

The Visual Guidance Program has an on-going commitment to seek out new technologies which may be applicable to airport visual aids. We encourage companies who may have such technologies to contact us.
