A Look Inside The Gulfstream G500
Gulfstream G500 operators live in a 500+ kt.-world where few, if any, competitive aircraft can catch them. They tell BCA they only slow down to Mach 0.85 cruise when they need to stretch range to the maximum. And many say their normal cruise speed is Mach 0.90, equivalent to 516 KTAS in ISA conditions above the tropopause, even faster at lower altitudes where it’s warmer.
Gulfstream officials fully appreciate that the G500 represents more than just a new model. It’s a step change in aircraft design that is the basis for the new G700 flagship and other unannounced models in the pipeline. Thus, they are committed to ironing out the G500’s wrinkles. And it appears they are succeeding.
