To interpolate you will need to figure out the percentage between the two temperatures
We take the difference between the chart values for 20 and 30 degrees Since we subtracted the 27 from the lower value we will add in this number ot the lower chart value This is a difference of 70 feet
When you’re not flying at one of these intervals, you have to use a process called interpolation in order to accurately plan your flight
Interpolating is when you use the information about a set of conditions listed in your performance chart and calculate a value based on your specific circumstances that falls between the given intervals
Therefore the best angle of climb (produces the best climb performance with relation to distance, occurs where the maximum thrust is available The relationship between propulsion and drag is such that it takes a certain amount of power/thrust to overcome drag both on the high end (the faster you go) and also the low-end (the slower you go)

For most of the information in those charts there is not a single formula which would cover all aspects. The graphical way is the simplest and has...12
The equations, if they exist, are often rather non-linear and not enjoyable to calculate on the fly.10
As has already been pointed out, a lot of the data are not results of a (single) formula. Besides (non-linear) differential equations, even a lot o...6
