Gulfstream G150

[G100driver]

I've always been curious - does the high placement of the engines on the fuselage result in pitch changes with power adjustments?

It made the Gulfstream 100 a self flaring airplane. Pull the power to idle and the nose comes up!

I cannot speak for the Gulfstream 150, however.

Trimec is a great facilty for westwinds. I have heard nothing but good about them ... but they are not a service center. Sounds good on paper until the "f" it up and you are stuck with the bill.

GS in Savanah is not going to save your bacon when you are sitting at the hanger with "M" procedure to your MEL and the boss is waiting. Trust me on this one. Been there done that. No one makes his salary more than a good DOM.

Sounds nice though having a new Gulfstream to fly. Good luck.

TRIMEC is a Certified and approved 1124/1125 service center for Gulfstream / General Dynamics.....


last i heard....

1124 yes ... 1125/Gulfstream 100 I do not think so.

Gulfstream is very stingy with their authorized service centers. Especially on their current production products. IE G150. I would not expect this anytime soon.

As my memory is fading here in the sun, but I believe El Corta is the only 1125/G100 service center outside of GS/Gulfstream.

Gulfstream could care less about 1124 as they do not own the type certificate.

I take that back about El Corta. According to their web page there is no authorized service centers outside of GD/Gulfstream on the 1125/G100.

Gulstream took away all the service centers for the 1125 with the buyout of IAI.

G100- Good advice (as usual).

I'm curious how much "better" the speed and range numbers are working out. It's using the -40's isn't it? Seems like the engines would be working pretty hard to push the extra weight/size around.

 

[G100driver]

No clue about the G150. The only thing I know is the Gulfstream redesiged that abortion of a slat/flap system. While the wing looks the same the internals are different than the G200/G100.

They also put a new nose on as well to quite down the world's loudest cockpit.

Westwind dude ... Good luck with your new job.

G100,


Do you spend as much time on the porn sites as you do this board ? When are you going to change your name to F2000EXSkyGod ? Just kidding.

For the life of me I cannot figure out why a guy would spend so much time on his computer when there is a cold beer and a warm beach full beautiful things to look at ???????

I for one thing the G150 will be a great plane, just like the 1121 I use to fly......

Spoken like a guy who flew .... and still flies a POS Have your brakes caught on fire yet ....

As for the beach and beer ... This was a crappy trip. I spent much of it sick.

 

[P3-Adub]

POS ??? At least I am not lining the pockets of our faithful French friends. Think you and Jane F. might dine at the same establishment ! Oh wait, Bombardier is part French too, crap...

And no, my brakes have not caught fire, lately.....

Hasn't anyone told you to not drink the water down there ? Or did you get a little more than perfume on your collar at the Donkey show ? Jeez, can't take you anywhere....

We met with Gulfstream the other day. Our LOI and financing is offered at $13M

They say it's gonna be a 2700nm aircraft at .75 mach with 4 pax. They're also saying it will do NY-LA at mach .80 and land with 200nm alternate fuel and NBAA IFR reserves, using NBAA 85% annual winds. That is with 4 passengers as well.

One nice thing about the G150 which westwind and G100 operators may like, is that it does not have a wet footprint. The sales director from Gulfstream stated the G150 will do Hawaii from California without a problem with 4 pax, and if you lose an engine going either direction, drift down and fuel burn are not a problem to make it to a diversion airport.

I know a couple of Astra/G100 and Westwind operators that routinely fly their aircraft to Hawaii. One says with 4 pax he can fly there from the San Fransisco area during the summer, but that he lands with 800 pounds of fuel. In the Westwind we're only talking 35 minutes of fuel at altitude. Both the Astra and Westwind have a huge wet footprint. You wont ever catch me flying one that far out over water.

The only thing I don't like about the G150 is it's Full Fuel Usable Payload. Load this thing up with it's 10,250 punds of fuel and you can only haul 800 pounds of pax/bags/etc before you reach MGTW.

Runway performance looks much like it does with the Astra SPX (G100). It uses the similar/uprated TFE731-40R-200G engines, but with improved/updated FADEC control that squeezes an extra 5% of thrust out of the engines during takeoff and climb (4420 Lbs of thrust on the G150 vs 4250 on the G100). This also applies to hot and high situations. Cruise flight Fuel flow was also reduced compared to the G100.

For most day-to-day operations and pax loads, the G150 looks like it will have performance just slightly better than the G100. At MGTW (26,000 Lbs), at SL and ISA, the BFL is close to 5900 feet.

Again, on most days, with t/o weights close to what one would see with the G100, the G150 will be comparable with the former. Not too bad for a fattened up Astra.

I can say however, that while I believe the G150 will be successful, IMHO Gulfstream and IAI should really evaluate it's engine choice and the future of the Astra wing. It would be nice to have more thrust. Maybe TFE731-5 series or Pratt & Whitney's PW306 series should be looked at. The Citation Sovereign has PW306C's installed, each rated at 5,688 Lbs during takeoff. I like the higer thrust personally.

One other thing to think about. Maybe it's time for the Astra wing to grow some, or a new wing designed all together. I say this because of the Citation Sovereign. At it's MGTW of 30,000 Lbs, the Sovereign's BFL at sea level on a ISA day is only 3,580 feet!. Basically you can add on another 2000 feet if you're flying the G150, and you're weighing 26,000 Lbs in it. (G150 MGTW is 26,000 Lbs)

Granted the Sovereign has more thrust and is more of a straight wing with a ton of flap surface as compared to the G150, but you would think having slats and flaps would help the latter.

Last not so great point, which I did mention above, the G150 is not a Full Fuel Full Passengers airplane. The Sovereign on the other hand is,.. and while on a east coast-west coast trip it may take the C680 an hour longer to get there, at least you can load it up with full fuel and 8 passengers and still fly 2,679 nm. The G150 will only do 2,700 NMs with 4 passengers.

Those are just my thoughts, maybe Gulfstream/IAI will see the light.
I have spoken to my boss about these points, and he is still interested in the G150. Nothing is signed yet, so we have time.

If we end up flying a G150 I will be just as happy with it as I am right now with the Westwind, but with other, better options out there, should we be looking at them?

I am starting to wonder if maybe we should go in the direction of the C680, but I know some people feel Cessna is the "plane in a box" manufacturer, meaning their products are not built like tanks, and they are the "Ford of Aviation."

Any thoughts on this? Should I and the other pilots attempt to go in the direction of C680?
