Fuel Burn Vs Weight
B738, anyone got a rule of thumb or preferably a formula for working out extra\reduced fuel burn for a TO weight that differs from the computer plog TO weight.
Jeppesen used to provide this on our plogs for a previous company, eg 78kg per 1000kg above or below scheduled TO weight. Their calculation obviously based on flight time and flight profile. Brgds |
Thumb rule - you save 3,5% of the weight reduction.
Offload 3000 kg - you save 105 kg. fuel. Brgds Empty |
Agree with Empty Cruise's figure of 3.5 %, but it's 3.5% per hour.:ok:

DOH!
Of course Slick - I should start reading my own posts after posting them :O - might catch the odd embarrasing omission.
But hey - you did the work for me :p Stay safe - brgds from Empty |
Thanks fellas,
