This looks like a very nice tool to enhance the 707 sim.

I think the only parameters that would alter results are if we use different weather add ons that produce wind variables at climb/cruise/descent. ( and then really only over long distances)

Of course with modern FMC's we can enter these variables and see the resultant fuel calculations (assuming the FMC logic works!) With the 707 its all down to tables and maths!

Anyway, it beats having to use the fuel dump when you realise your going to be overweight on landing! ;D

Will the tool require MS Excel or will it run as a stand alone tool?
