When Gulfstream’s G650 enters service later this year, pilots will find a pleasant surprise, a Honeywell RDR 4000 3-D weather radar that is far easier to operate than earlier systems. The radar has been flying for a few years on airliners, and the G650 is the first business jet application. New features just implemented on the RDR 4000 include turbulence detection, hail and lightning display and a new attenuation display.
