TAKE-OFF DATA
Based on the above determined take-off weight of 31’715 kg (69’917 lbs.) we will now define the critical
speeds for departure. EDDL runway 23L is long enough (9’843 x 148 ft. / 3000 x 45 m) so that there is no
restriction and we can use the speeds from the speed card for 70’000 lbs. (31’751 kg) that can be found in the
Quick Reference Guide. Or for those lazy RW pilots under us we go directly to DAVE and get our speeds from
there. You can even insert them automatically, inputting these speeds manually is a real chore.
We will be setting flaps to 8 degrees for the take-off and our departure airport altitude is close to sea level.
Outside temperature is less than 10 °C. This concludes in the following speed selection (DAVE sometimes
calculates slighty different values due to more accurate weight info):
