How to interpolate series#

JunJug, If you run the same series of calculations at 2500, youвЂ™ll see you get the midpoint value that you would get simply by dividing by 2. Add that to the takeoff distance at 2000 MSL and you get a total takeoff distance of 1630.5вЂІ The result, 85.5, is the additional takeoff distance you will need at 2643 MSL over the takeoff distance at 2000 MSL.Д¤. The 2643 MSL airport is 643вЂІ higher than the 2000вЂІ airport, so we take the 0.103 and multiply it by 643. ThatвЂ™s the change in takeoff distance for each foot increase in altitudeДЈ. divide that result by 1000, giving you 0.103. There are shortcut formulas, but the long way may help with understanding what the shorter formulas are doing.ДЎ. The whole idea is to take two sets of known values, find the rate of change between them and add the result. ItвЂ™s probably too complex a process to describe in a short post, but letвЂ™s take a step back from a formula to the concept of interpolation. Your result give a shorter takeoff distance than the midpoint at an altitude higher than the midpoint. The midpoint between 20 is 2500 and the midpoint between the two takeoff distances is 1611.5. Wes, I think you may have kicked in a wrong number along the way. It isnвЂ™t going to affect your fuel consumption all that much. I would either interpolate the surface temperature with the first temp at altitude or subtract 2В° c / 1000вЂІ for a close approximation. The reason this is the case is due to coriolis effect for the wind and surface heating for the temperature. The forecasted winds and temperatures (FD) report does not include winds where the reported altitude is within 1500вЂІ AGL and the temperature is not reported when within 2500вЂІ AGL.

I put the decimal in front so we would not have to divide by 1000 later. Add the higher figure multiplying it by the difference between the higher altitude and your altitude.

Take the lower figure and multiply it by the difference between your altitude and the book altitude. The interpolation process though is this: Say you are at a field elevation of 2643вЂІ and the POH gives you numbers for 20. I typically take the takeoff or landing distance of the next higher one and use that. Being extremely exact is nice but I have found that flying the airplane not to be so exact. Interpolation is difficult sometimes but I have found a way to get a close of an answer as you like.
