This is kind of silly, but what is with the beacons, or lack thereof on the GV? The one lonely beacon is mounted behind the main gear, and seems like it is only visable when you are directly behind the aircraft. Is drag so critical that they couldn't mount one on the top of the fuselage, or at least on the belly behind the nose gear?
You are right that drag is critical and Gulfstream does everything it can to minimize drag count, but that is not what's at play here. The jet's traffic avoidance lighting is too powerful to be used on the ramp.
There's no shortage of lights on the Gulfstream, in addition to the landing lights, three taxi lights, wheel well lights and emergency lighting system the jet has:
The beacon which is used primarily to alert outside observers the aircraft engines are operating.
The strobe lights which provide the aircraft with a lighting system that will make it more visible to other aircraft. It consists of three strobe light assemblies, one in each wing tip and one in the tailcone. We don't turn these on until taking the runway and turn them off leaving the runway, so perhaps you haven't seen them.
The double navigation lights provide the aircraft with lighting for navigation and directional recognition.
Ice inspection lights provide a means of illuminating the leading edge of the wing for ice inspection and to increase aircraft conspicuity in the terminal area.
Wing tip lights that assist in clearing the wing tips while taxing at night and for increased visibility in congested areas.
Pulse lights which pulse the 600,000 candle power landing lights below 18,000 feet, again for greater conspicuity.
Logo lights which illuminate the vertical fin and the lower surface of the horizontal stabilizer and look cool.
