G-IV Fuel Burn

[Beechjetr]

Does anyone have some quick hourly fuel burn numbers for a G-IV or G-IVSP?

Thanks.

I've found that 4, 3.5, 3, 3, 2.7, 2.7, 2.7 etc. works pretty well for me... Hope this helps...

What's the max fuel? What's a typical min landing fuel #? How many hours endurance?

Could you make it to Buenos Aires from Southern FL?

If I remember correctly max fuel is 29.5K, we used 5-6K typical landing fuel, and I've done 8+30 at .80 and landed with 4500.

As a rule of thumb, I found that the first two hours you burn 8000 if heavy and 7000 if light then I use 3000 for each additional hour. Generally I use 5000 as minimum planned landing fuel, depending on the weather. Have landed with less than that a few times. Keep in mind that with full fuel, you will need about five hours to get down to landing weight.

8000 pounds are you NUTS!

Here are REAL world numbers.
4100 - 3100 - 3100 - 2800 - 2800 - 2500

For normal 2-4 hr trips are real goog gouge is 3000 perhour PLUS 1000 more for the first hour. Normal Landing 3-5000 .

BTW the GV fuel burns are ABOUT the same but go on and on and on..

These are the numbers I use for the G-IVSP and the GV. The G450 and G500/G550 will do better.

Too hard for me. I've used 3k per hour plus 1K. Always worked fine. For very long trips I used CFP

I too always rough in flight time multiplied by 3 plus 1000 pounds. Then compare against the FMS and Flight Plan.

Always worked pretty good.

That doesn't work at Mach 0.85 in either the G-IV or GV. Good post GV. SS
