LED Implementation Issues
ICAO Visual Aids Working Group formed a Sub-Group on LED implementation on Aerodromes
Airport Safety Technology R&D hosted first meeting at the FAA Technical Center in April 2006.
Sub-Group identified 11 issues to be resolved.
Consolidated to 8 issues:
The Energy Independence and Security Act of 2007 is available at:http://energy.senate.gov/public/_files/RL342941.pdf
Incandescent lamps generally produce energy as a small amount of light and a large amount of heat (IR).
LEDs being a more efficient light source, produce more light compared to very little IR and not nearly enough to be detected by the EFVS systems currently certified.
Enhanced Flight Vision systems (EFVS) utilize the wasted energy in the form of IR generated by current incandescent lamps.
Enables incandescentsignal lights to be detected at further distances than is possible by the unaided eye under certain weather conditions such as fog and snow.
Utilizing these systems, aircraft so equipped, may see the required cues (Approach Lights) to continue their approach at CAT I DH (200ft) when these lights arenot visible tothehuman eye down to 100ft.
May not need emitters at every light position
IR Emitters only
A team of FAA and Industry experts formed to design an Airport Lighting Infrastructure to take full advantage of new lighting technologies.
Elevated Runway Guard Lights
100 W (PK30D) quartz
AC 150/5345-46C (2006)
Area of Interest
Identifiable as an RGL
40:1 scaled apparatus
Based on using single 5mm LED to be equivalent to an 8-inch signal
Pilot eye height: 28 ft → 8.4 in
Viewing distance: 158 ft → 47.5 in
Taxiway width: 100 ft → 30 in
RGL from taxiway edge: 17 ft → 5.1 in
Foggy day setup
1.25 Hz@ 70%or2.50 Hz@30%
Field study is needed to validate results before final recommendations are made.
