Gdesi brate. Right i've just bought this toper tool and everything was lloking fine, however the MAX TOW is incorrect as i was going from KIAD-OMDB and put in the TOW as 347835KG and the INTX 3800M which was the full TORA for 01C. All the wind QNH info was correct with flap 15 setting, but when i pressed calculate, it said i exceed the limit for the selected runway. I ignored this and applied a 35 degree ass temp and everything look fine. Later i tried this in DUBAI the TORA was 3800 M aprox with the same TOW and i couln't get a calculate.
