[Solved] Fuel burn issue with FSX 738

[Glenlek]

Thank you guys for this forum so much! I finally have some numbers that work very well for me, hope they help you as well.

Flight Plan:
Distance: 913.6 Nm
Estimated fuel burn: 15,140 lb
Alt: FL 220
Speed: 315 knots

Actual numbers after the flight:
Distance: 914 Nm
Fuel burn: 16,157

Numbers:

Engine.1 = 0, 16.1, -3.2 //(feet) longitudinal, lateral, vertical distance from reference datum
