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

A take-off and landing distance calculator would be too comoplicated, in my opinion, to setup and use correctly. Just note how many people have problems setting up weight & balance data. Also, these distances depend on a lot of variables: temperature, dewpoint, atmospheric pressure, altitude, weight, surface conditions, wind and pilot skills. I believe it would even be dangerous if people delegate these considerations to a piece of software and possibly faulty input.

Without wanting to tread on anybody's toes, I am the kind of guy who questions why people even bother to get into a plane if they have the software do all the prep work, the GPS do all the nav work, and the AP do all the flying.
