Looking to see what people are using for FP.com fuel burn rates on the hawker 850xp so I can input and compare on short and long leg flights. thx BB

hello,count for the first hour 2000 lbs
2=second hour 1600
3 third hour 1450
4 hour 1400
5 hour 1400

Thats what were getting with our 800XP (without winglets.) Were getting winglets on our 800XP in June, hoping it will make a noticable difference. I heard up to 10% difference. An extra 200 miles or so would be nice. We'll see.

Winglets are great. We can up to 39-41 at max gross and still get .77M out of our XP.

Is there any validity to keeping the speed back at .75 instead of .77 since some have said the small gain in airspeed is not worth the cost in added fuel burn.

Thoughts?
