White Flashing Omni-Directional Approach Lights (ODALs) | FAA L-859
Omni-Directional Approach Lights (ODALs)
FAA Type L859 Style F
ODALs (Omni-Directional Approach Lights) are used to identify the approach end and centerline of the runway. The omnidirectional horizontal beam pattern, bright flashes and a sequential strobing flash pattern that rolls toward the runway threshold helps the pilot identify the runway in use. Three intensity settings allow the approach to be used under changing weather conditions.
