A 5 kt difference is too much, suggest you investigate if the FMGC speeds are balanced while the paper weight/speed are optimized. Strongly suggest that you use the paper weight/speed combination.
Old_smokey,
Will you please explain this....
Assumed Temperature above the environmental limit. Why do you not use the FMC?
The jungle jet comes with one of the best software suites that i've ever seen. Digital AFM, Runway Analysis, Enroute and all manuals available in PDF format. The output was defined by us for commonality, so at least for the purpose of takeoff charts they are identical to our Boeings. Let me know if you have a buddy coming here and i will give you a set.
Hope you enjoyed visiting the revolutionaries
