No figures in any ops manual/perf manuals . Performance guys at work have no data
I'll put in in mathematical form for you :
If flight plan fuel is (A)
taxi fuel+
ff (all eng) +
10% of ff +
Approach fuel +
ffr (30 min)
And eng out requirement preflight is (B)
From dp1 need
ff+5%+ffr+approach fuel
Where in this case dp1 is takeoff...
How do we know A > B when we can't calculate ff in (B)?
It is capt responsibility to carry enough fuel for e/o contingency and I can't see how the tools are there to do this?
