Good morning,

would it be possible to add the calculation of takeoff distance (in addition to weight and balance) to Skydemon ?
A model could be this slide rule ("T.O.P. Comp" brand):

which can be bought here:

many thanks and best regards

Because if the wide variability of conditions not easily included in such a calculation, whatever number you do get out will be worth next to nothing. This questionable benefit is countered by the added complexity of entering your aircraft's data into SD as well as the danger of pilots relying on this and then not making it.

There just are some things which are better left to the pilot's judgement.
