Phasing out Incandescent Lamps
The Energy Independence and Security Act of 2007
– Begins to phases out incandescent and halogen incandescent lamps in 2012
– Department of Energy (DOE) within five years is mandated to create an LED replacement for the PAR Type 38 halogen light
– Probably will not be compatible with MALSR voltage levels
The Energy Independence and Security Act of 2007 is available at: http://energy.senate.gov/public/_files/RL342941.pdf

Issues with Implementing LED Technology
Claim: LEDs can not be seen as well as Incandescent lights in low visibility?
True or False?
FALSE!Any source with the same Candela value can
be seen the same in a given visibility.
Except…

Perceived Brightness
There is a quantifiable “Brightness/Luminance” (B/L) conversion factor with LEDs.
• Conversion to Incandescent:– Blue B/L = 1.4– White B/L = 1.6– Green B/L = 1.4
• However, light scattered by Fog can desaturate LED signal colors reducing or eliminating the brightness advantage.

Observers noted that the Incandescent lost the GREEN appearance early.

LED Applications IssuesLED Applications Issues Chromaticity Boundary for Aviation White
– Preliminary results for Aviation White Chromaticity Boundary Changes:
• Yellow boundary could be moved from x=.540 to .440 which will help limit confusion between white and yellow signal colors.
• Blue boundary could be moved from x=.350 to .320 which will allow a more bluish white (CCT up to 6000 Kelvin) while not contributing to confusion between white and blue signal colors.
• To match CIE S004 for LED binning:
• Green boundary y=0.150 + .640x to 0.150 + .643x.
• Purple boundary y=0.150 + .750x to 0.150 + .757x.

Retro-reflective Media for Marking MaterialsRetro-reflective Media for Marking Materials Findings – Ground Based
1. All retro reflective beads tested proved suitable for use on aged Hot Mix Asphalt and aged Portland Cement Concrete.
2. Proposed new beads A and B proved suitable on aged Hot Mix Asphalt and aged Portland Cement Concrete.
3. Paint marking materials and included beads do not perform well on new Hot Mix Asphalt as airports typically can not afford to wait the appropriate curing time.

Findings – Airborne
1. The majority of subjects involved in the tests at both ACY and SAV stated they do not use runway markings as a visual cue on approach to the runway at night.
2. The predominate visual cues they focus on during the approach to a runway are the runway lights.
3. All but one of the subjects reported no difference in ease of detection between Type I and Type III beaded markings.

Automatic Switching technologies for Rwy Automatic Switching technologies for Rwy Centerline Lights in a Displaced ThresholdCenterline Lights in a Displaced Threshold
• The FAA Advisory Circular AC 150/5340-30D “Design and Installation details for Airport Visual Aids” states:
– “For displaced threshold areas over 700 feet (100m) in length and used for takeoffs, the centerline lights in the displaced area are circuited separately from the centerline lights in the non-displaced runway area to permit turning “off” the centerline lights in the displaced area during landing operations.”
• Teterboro Airport has this issue on both ends of runway 1/19.
• Air Traffic Control are indisposed to operating the interlock switch that manually controls the centerline lights.
Federal AviationAdministration
27
Project ObjectivesProject Objectives
• Evaluate and determine the feasibility of using varied surveillance technologies and safety logic to automate the activation/deactivation of Runway Centerline Lighting in a displaced threshold to support takeoff/landing operations.
• Install and optimize the preferred technology at Teterboro Airport (TEB)

Signs

Holding Position Signs for Runway Approach Areas
ATO is in the process of revising their current procedure, which does not require pilots to obtain a specific clearance to cross these holding positions.
In the revised procedures Pilots will now be required to obtain specific clearance to pass any holding position.
Federal AviationAdministration
32
Holding Position Signs for Runway Approach Areas
The RSO has identified a potential risk of runway incursions due to pilot confusion at the holding position marking and signs for a runway approach.
ATO would like to retain their current practice -therefore a different signage and/or marking may be required.

The LCGS Project Scope
• Develop FAA functional and operational standards for LCGS implementation that would support AIP eligibility for this system.
• Provide the foundational capability to support other runway safety improvements (e.g. RWSL, dynamic stop bar automation, …).
• Develop a cost-benefits case for the use of Low Cost Ground Surveillance Systems for airport operations.
MissionTo enhance airport operations by improving safety, shared situational awareness &
environmental impact, reducing airport operating costs and improving capacity and resource utilization
Federal AviationAdministration
39
LCGS Challenge
• Of over 460 towered airports in the NAS only 35 of the larger airports have or are slated to receive comprehensive surface surveillance systems (i.e. ASDE-X).
• Many of the excluded small to mid-sized airports have considerable surveillance needs that are not being met.
– Surveillance capacity is limited to voice reporting and field of view
• Many of today’s airports struggle with the challenge of improving operational efficiency and maximizing revenue growth opportunities.
Federal AviationAdministration
40
LCGS High Level Concept
• The currently developed LCGS solution is centered on the use of a Surface Movement Radar (SMR) to monitor ground traffic movements.
• SMR inherently presents some deficiencies (loss of target due to masking, plot clutter due to rain or grass reflection, flight label overlap, etc.) which renders the surveillance function less effective and could result in a lack of confidence in the system.
• SMR technology is characterized by high maintenance and lifecycle costs.
Federal AviationAdministration
41
LCGS High Level Concept• Researching existing technology the framework
recommended for an LCGS system is the coupling of a network of non-cooperative (i.e. optical and thermal devices) sensors and a Mode S multilateration system.
• This will provide the most flexible and modular framework for the smaller airports as multilateration systems can be easily adapted to smaller coverage areas with complex layouts and no vertical extension.
• This network design would provide several levels of redundancy which would translate into continuous operational availability and coverage.
Federal AviationAdministration
42
Status• Concluded final preliminary study on strengths, limitations and
cost effectiveness of prospective systems.
• Conducting site visits to deployment locations of prospective systems.
• Work in concert with the Advanced Technologies Development & Prototyping Group (AJP-67) at the three approved test sites of San Jose Airport (SJC), Long Beach Airport (LGB) and Manchester-Boston Regional Airport (MHT).
- Test candidate systems against predefined functional
requirements. - Evaluate operational feasibility of candidate systems.
