California-based New Bedford Panoramex (NBP) has contracted with the FAA to replace the aging incandescent bulb-powered precision approach path indicator (PAPI) systems at 100 airports around the country, according to the initial contract. NBP’s new “next-gen” precision approach path indicator (PAPI) systems use light-emitting diode (LED) lamps. In addition to providing greater reliability and durability, once implemented, the LED systems, will cut energy costs by 75 percent when compared with the incandescent versions.
