Gulfstream Aerospace Corp. has received approval from the Federal Aviation Administration (FAA) to retrofit Gulfstream IV, GIV-SP and GV aircraft cockpits with light-emitting diode (LED) lamps via two Gulfstream aircraft service changes (ASCs).
The LED lamps were developed by Gulfstream engineers and suppliers to replace up to 700 incandescent bulbs throughout the cockpit, depending on each aircraft and its configuration. LED cockpit lamps offer better performance, reliability and cost-effectiveness. Because they have a much greater lifespan, the new LEDs reduce maintenance and material costs. The colors — blue, white, red, green, amber — are richer and more vibrant than those emitted by the incandescent bulbs. The LEDs also offer a purer color light and operate at temperatures approximately 80 degrees cooler.
“The old bulbs require considerable maintenance time, whereas the new lamp technology can be installed quickly and without significant modification to the aircraft,” said Mark Burns, president, Gulfstream Product Support. “These new, more reliable, energy-efficient LEDs emulate those that we already have in the G450 and G550, and they provide the operators of legacy Gulfstream aircraft the same advantages afforded the G450 and G550 operators.”
The new cockpit LEDs are available now and can be installed in three days or less.
