Most of the Forbes List have planes ranging from Trump's 727(he also has a Gulfstream of some kind) to the Arab's 744's.
Generally, they settle on the Gulfstream IV
's or V's, Falcon 50/900 or GLEX's. There are a smattering of BBJ
's around but a lot of FBO's can't accomodate an airplane that large. Even the GV
is tight on a lot of ramps.
I wouldn't want to do LAX
in a bizjet. As it stands, we do LAX
with a fuel stop in a GV
. I've done the midwest to Istanbul non-stop(in fact, most of the way, we did M .85). Over the oceans we use Equal Time Points which gives us the rough equivalent of ETOPS without being required to stay within the 180 min. range.
The engines and systems on the aforementioned aircraft are as advanced as anything in the air. The GV
has the same level of redundancy as the 767/777. In fact, the APU's have a larger envelope than those of the airliners.
I remarked to my friend as we were over the N.Atlantic a couple of weeks ago that we used to approach a crossing like a mission to the moon. Now, we just jump in and go without a second thought. Some of that stems from experience but the bulk of our confidence is the aircraft and it's systems.
Sorry to hijack the thread a little.TC
