POH. You may have to obtain the Pressure Altitude by calculating it using your Field Elevation and Atmospheric Barometric Pressure reading. By this calculation, you expect to be airborne at midfield and accelerating skyward. It will give you parameters that must be met in order to make the chart as accurate as possible. These are usually also available in tabulated data form, but not always. But there should be charts for different flap settings, wind speeds, elevations, temperatures in other words, enough to calibrate the model for all those parameters. Parabolic, suborbital and ballistic trajectories all follow elliptic paths. does not recommend for that altitude - power settings above about 70% power are not Employer or Employee: Who is Responsible. Once you have time and speed, calculation of distances should be easy. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
