I have a couple of curves that describe the fuel efficiency of a plane at various speeds with two different gross weights.
The first curve is with the plane fully loaded 16000 lbs gross weight:
y = 0.0115x2 - 3.0703x + 258.19
Where x is the speed and y is the MPG.
The other curve describes the speed versus MPG with a 9300 lbs gross weight:
y = 0.0093x2 - 2.396x + 188.04
If I want to estimate the efficiency at an arbitrary gross weight (say at 12000 lbs), is there an accurate way to do this easily?
I was thinking about just performing a linear estimation between the two (~40% between the 16000 and 9300 y values for 12000lbs).
Is there a better way to do this?
Thank you in advance.
