Phase II: Request For Proposal (RFP)
        - Offerors shall propose to the FAA a validation plan.
        - Offerors shall propose steps to develop a FAA L-862(L) LED with an IR emitter, to be designated as L-862(L-IR) and to ensure their compatibility with aircraft currently equipped with EFVS.
        - Offerors shall propose steps to develop a standalone IR emitters and to ensure their compatibility with aircraft currently equipped with EFVS.

Legacy L-862 High Intensity Runway Edge Light

Uses a quartz halogen lamp with a tungsten filament. 

Ideal source for EFVS systems since 90% of its radiant energy is in the infrared (IR).

Filament’s small size and flat shape ideal to produce the required controlled beam shape.

The lamp’s IR output decreases rapidly above 2 microns and effectively zero above 2.5 microns. Due to absorption of the glass used in the filament housing.

Because of this, EFVS should be designed to operate in the IR transmission window of 1.3 to 1.8 microns.

Legacy L-862 High Intensity Runway Edge Light

L-862 - Incandescent

L-862(L) - LED

Status

Company 1:

Their objective is develop an emitter that has an equivalent IR main beam intensity and angular spread as existing 120W L-862 fixtures and demonstrate a method to activate the IR emitter only during those periods of time most useful for EFVS operations.

Has selected an IR source for a stand-alone emitter.

The IR prototype will include an alternative material for the lens, rather than glass, to allow for a wider spectrum of IR, out to 4 microns compared to 2.5 microns through glass.

Status

Company 2:

Developing a totally new Integrated Visual and IR fixture design.

Selected an IR source.

The design package is complete. 

Visible and IR tests are complete.

Status

Company 3: (No award to date)

Initial overall proposal was not accepted, however they introduced a unique IR source.

FAA requested a scaled down effort, Company 3’s 11/07/16 resubmittal’s effort and scope was still to large and required more funding then available.

Status

Company 3: (con’t)

FAA requested another submittal asking for smaller scale effort :
        - Build one laboratory prototype equivalent in size to legacy L-862 HIRL fixture. 
        - Measure IR output and IR beam pattern of the laboratory prototype.
        - Provide a final report including all (legacy and prototype) data measurements.

Company’s submittal on 2/09/17, funding request still over funding available. Proposal still under consideration.
