It has only been done once before, in 2007. With a smaller jet. More advance coordination w Tiger Tiger might have been useful. There is a prop shuttle between Reno RNO and BRC.

I've done it in Herks on shorter, less improved strips... Best bet is to wait for word from Gulfstream's chief pilots. There may be additional considerations with respect to warranty and insurance, hurdles which should also be cleared before attempting this in such an expensive airplane.

I wouldn't think the question is if the feat is possible bt rather, whether or not it's advisable, or safe, given the operating requirements of the aircraft, the limitations of the runway, and federal aviation regulations. Even if Gulfstream gives their go-ahead, might a special permit be required from the BLM?

A key consideration is whether or not the runway will hold up. It's not just the gross weight of the aircraft. Rather, it's how the aircraft's landing gear and tires distributes it's weight across the runway surface. A key input, believe it or not, is the aircraft's tire pressure. There are several systems throughout the world, including the older ST/DT/TT etc. system, as well as the newer ACN/PCN system. So far as I know, the runawy at BRC has never been evaluated, other than by means of actual flight testing. If the runway bearing strength is insufficient it may result in a degraded runway surface, or worse, rutting and possible damage to the aircraft's undercarriage.

I would advise you to proceed cautiously, ensuring that all issues are acceptably addressed. Coordinating with the BRC staff would probably be prudent, too.
