FAA-E-3007 (W/ CHANGE 1), FEDERAL AVIATION ADMINISTRATION PERFORMANCE SPECIFICATION: FOUR BOX, LIGHT EMITTING DIODE (LED) PRECISION APPROACH PATH INDICATOR (PAPI) - VERSION A (16-JUN-2009)

FAA-E-3007 (W/ CHANGE 1), FEDERAL AVIATION ADMINISTRATION PERFORMANCE SPECIFICATION: FOUR BOX, LIGHT EMITTING DIODE (LED) PRECISION APPROACH PATH INDICATOR (PAPI) - VERSION A (16-JUN-2009)., This specification sets forth the requirements for a Precision Approach Path Indicator (PAPI) that is used to provide accurate approach path guidance to pilots of landing aircraft. The PAPI consists of four Lamp Housing Assemblies (LHA), a Power and Control Assembly (PCA), and an aiming instrument set if an aiming device is not built into the LHA. This specification specifically addresses the use of light emitting diode (LED) illumination sources that will replace incandescent bulb technology. The use of LED illumination sources in lieu of incandescent bulbs shall meet all PAPI operation requirements, provide much improved reliability and maintainability characteristics, and will significantly reduce life-cycle system operational costs.
