Photo- "Break Away" In A Gulfstream-V /C37A

Thu Jan 10, 2013 8:00 pm

Is it wise to do a "break away" fighter jet style in a high-performance commercial jet like a G-V? (Granted it looks like it was during an airshow).. I like the spotter's comments

Well it is not a "Gulfstream V" but rather a C-37A, the difference being the former is a civilian jet and the latter is a "spec'd for the government" version of the jet. It quite likely has additional systems that may allow things like this without problems (not that I actually know).

I guess the real question is what are the differences between a "stock" G-V and the C37A?

No reason not to, especially if the aircraft is lightly loaded. Passengers may not appreciate it and it isn't something you'd probably want to do on a regular basis, but occasionally it's probably just fine.

As far as the airframe goes, nothing I think. The C-37 has some additional avionics and maybe some extra bolt on type equipment, but I don't believe the engines, airframe, etc. are appreciably beefed up over a bone stock G-V.

If a 707 can do a barrel roll, I'm sure this is perfectly acceptable in the Gulfstream.

I fly G-V/550s.. Would be great if I could attempt something like that, but I won't (I kind of need my job)

This photo will be on as my screensaver for many days

I am thinking it may have different oil and fuel elements that make it safer to do this kind of thing.

Of course probably the real reason this plane can do this is because unlike g500 above, the pilot doesn't worry about not keeping his job because quite frankly the "company" that owns the plane doesn't care that much about doing damage to it. I meant hey can always get another one if they need to.....

An overhead approach, while awesome-looking, really isn't that big of a deal. I have personally seen a C-5, C-17, two C-130s, a KC-135 and an E-3 do an overhead approach.

Just YouTube airliners at air shows. What an empty 757 or even 747 can do is impressive. Remember these airplanes are made to withstand a lot more than even a horrible flight with terrible turbulence.

I know the chief pilot at John Deere and he mentioned to me one day that the wing on the G-V/550 is so big that you could do an 80-90 degree back and hardly even feel it. I think he was slightly exaggerating but he said the big wing is so comfortable that aggressive maneuvers like that aren't nearly as uncomfortable as you'd think they'd be or like they might be on an airliner or other corporate jet with a smaller wing. As a side note, that's one CLEAN plane! I always appreciate how corporate flight departments take care of their equipment (understandably) compared to the planes I fly.

the G-V/550 wing is pretty darn long..... G-V/550 vref speeds are usually around 115-120, because of the long wing.

A properly executed barrel roll is a 1G maneuver throughout the roll.

The maneuver seen in the photo in the OP would likely be higher than 1G.

Considering there is no reference in the photo to determine the bank angle, it probably was not as steep as is being assumed here. GV/C-37 max bank angle is listed as being 60 degrees, and I am guessing these pilots did not exceed that limit.

When I saw this picture, it reminded me when I was down at Norfolk Naval Base for work last summer. We were on one of the piers walking to a morning meeting and I happened to look out over the bay and saw an inbound Navy C-37. I was somewhat surprised to see as it got closer, it still had its gear up and had maybe 5-10 degrees of flaps down, but was going well above 200kts. It flew above us at around 1,000 feet and once they got a little past midfield, the pilot did a carrier break and came around to land. I had never seen that performed by a Gulfstream, and thought it was the coolest thing to see. I want to say the bank angle was between 30-45 degrees, but I may be wrong. A few mintues later after the C-37 landed, an E-2 and a couple F-18s did some breaks and the C-37 was just as smooth and agile as they were in the break.

An overhead pattern is also just a 1G maneuver. It is no big deal for the airplane.

A 45º overhead would produce 1.4g (as would any level 45º banked turn). The KC-135 is rated to 2.5g in certain conditions.

So is just about every commercial jet Aircraft.
