No problem in a 450. If you want to stretch her out a little longer and be a man, taking her up to FL450 will definitely get ya there, even at .84.

Unfortunately the 450's are too pricey.........but let's just wait and see.........

Really...

Longest flight I ever did on a IV-SP was 10 hours flat. Miami to Milan. 2 Pax. Landed with 2600 lbs.

Must be well below ISA over the N.Atl.

That and you have to be 25,000 lbs. under MTOW AND at .83 for an ISA day. AND no headwind...

EINN or KBGR for me.

what are you saying? you won't extend the range doing m84. we are talking about a g450 not a g550. please clarify

I don't speak PlaneView, but I do know the GIV pretty well. The airplane is very happy (and fuel efficient) at .80M. LRC is a moving mach number, so once you reach the coast out point LRC really isn't an option. At FL450 you might get .82M or .83M - if you're in MCT. Of course, then your fuel burn goes up...well, you get the picture.

The other issue coming from Italy (or anywhere in Europe) is being able to take a full fuel load. My experience in LIRA / LIML / LIPZ / LFMN - etc. has shown a top off will only get you about 28,500# due to differences in specific gravity of their Jet-A. So, be careful going westbound. If you flight plan assuming a full fuel load, chances are you're not going to get it.

YMMV

 

[semperfido]

I agree with what profrac said. G4 or G450, they both like M80. not M84

 

[G21Agoose]

So what you're all saying is a 900ex. Thank you all for the info.

back to the original question I see:
LIRA-KTEB
ETE / Speed / Distance: 8 hrs 51 min. @ M80 3881 nm
Average Wind Component: -23 Headwind
Total Fuel Main Burn: 26299.00 lbs. | 3944.85 Gallons | 14932.88 Liters
Flight Levels: FL400, FL380, FL400, FL430
Weights: Takeoff: 73900 lbs. Landing: 48001 lbs. Payload: 1500 lbs.


that will leave you approx 2500 lbs in Teb, if you allow for 29K fuel at Lira. So, yes it could be done.

One little typo and it's off with his head....

OK, so I'll mea culpa on this...

should be FL 450 even at 0.80M assuming 68% headwind probability at ISA of 24-29 kts. You'll still make it.

Landing a G4 with 1700 lbs. is illegal and stupid. That is from me the former FAA Inspector and Gulfstream Test Pilot in Savannah.

Leaves you with a resonable 2200-3000 lbs if things go as planned.

Thanks 2EASY, nice to see the numbers. I have seen 900EX's for 25-25mm now and even EASY's way under 30mm but we're looking at sub-20mm- we'll have to wait and see.

Thanks for all your replies.

Stupid = yes; illegal = no.

Whoa...my longest leg on straight GIV was 8+45, landed w 4400. Anything 9+ is a fuel stop in that airplane. Call me a pu$$y, but it is simply not worth it.
