Loadsheet from dispatch..

Hi all !

I'm back from holidays and fly again.

I used EDDK LPPT Flight plan and It seems there is a little problem in it.

The 747-400FPW has 165086kg DOW.
I add 11200kg cargo.
ZFW is: 176286kg (It's OK)
I planned 8400kg Taxi (It's to much, I know. lol)
Trip need 35400kg.
Contingency: 1770kg.
Alternate to LPPR: 7410kg
Final Reserve: 7176kg.

Total fuel: 60156kg.

Take off fuel is 55956kg (It must be 51756kg because Total fuel - Taxi fuel = 60156kg - 8400kg)
Then TOW must be 228042kg: ZFW+TOF = 176286kg + 51756kg instead of 236442kg given in FP.

Off course LW and Remain are wrong too.

What do you think about?

Cheers

Pierre

Chalut!

Nah, I'm sure it's ok. You can never have enough taxi fuel :lol:

Take off fuel is 55956kg (It must be 51756kg because Total fuel - Taxi fuel = 60156kg - 8400kg)

Not quite correct. If you deduct all the taxi fuel at departure already, you will have no fuel after landing to roll back to your gate (theoretically spoken)
In other words: the 8400 kg must be used for the departure airport AND the destination.

So what I do is to simply cut it in half (because I have no clue about your actual taxi distances). So there's 4200 kg for the taxi at EDDK and another 4200 kg for LPPT. The latter still add to your TOF/TOW. You follow me?
Thus the TOF is perfectly ok from my point of view.
However, it seems that the TOW is too high by ... exactly 4200 kg (surprise, surprise). Looks like the work of a bad programmer...
Will be checked and possibly fixed.

All right Peter.

I'm wrong, but I've discovered a little bug.
Your explaination is very clear, Thanks.

So long

Pierre
