Abstract

The NASA Langley Research Center is conducting a feasibility study to show that a Forward-Looking Interferometer (FLI) can be used to detect and measure hazards to aircraft. The FLI concept is an aircraft-mounted Michelson Fourier transform spectrometer capable of measuring atmospheric conditions ahead of the aircraft for the purpose of detecting hazards to the aircraft or determining other information relative to flight deck requirements. Hazards of interest include turbulence, low visibility, slant range VFR/IFR visibility transitions (by evaluating optical extinction parameters), volcanic ash, icing conditions, wind shear, and wake vortices.
