How are you planning on flying the airplane - Max cruise thrust or constant mach? What are you trying to figure out?

This is what I use as rough planning inthe Astra Classic:

1st hr 2000#

2nd hr 1500#

3rd hr 1400#

4th hr 1400#

etc..

Assuming that you're going to use max cruise thrust in your SPX/G-100 you'll burn 1800 pounds the first hour and around 1400 pounds every hour after that. The SPX will burn less fuel on any given trip than a Classic or SP.

Depending on the weights, you can plan on a solid 460 KTAS and maybe 5 kts more if you're light. The G-100/SPX is one of my favorite planes to fly - it's a real scooter.
