Hello everyone,
Please bear with me.
In our company flight plan, the format goes like this,
R/W limited t/o weight.........79.0 ( let’s say the max structural t/o is for today)
Max Ldg weight.....66.4
B/o fuel..................10.0
Ldg limited t/o weight.....76.4 (adding above two)
Max ZFW......62.7
Required fuel....13.5 (excluding taxi)
ZFW limited t/o weight....76.2 (adding above two)
planned zfw...61.0
planned t/o weight...74.5
landing weight....64.5
Now the problem I’m facing about how much extra fuel I can take for this flight. I know maximum time and easy calculation is just to subtract ldg weight from max ldg weight which gives us 66.4 minus 64.5= 1.9 tons. But in the above case we are limited by zfw limited t/o weight which is 76.2 (lowest of the three above) so should we minus this from planned t/o weight 76.2-74.5=1.7 tons. I am a bit confused here. If we take 1.9 tons then we are uplifting additional 0.2 tons here? So for the above what will be the correct answer? Thanks in advance.
