Interpolation?
Ok I'm having Saturday morning brain strain!
Could someone put me out of my misery and explain how I interpolate data?
Question: If 2,000ft = 1% fuel penalty what would the fuel penalty be at 2,100ft?
I know the answer is quite straight forward, but I just can't remember how you work this out (and it's not in my maths book) so could someone please help?
Thanks....
