JET-A Density - Temperature relationship
JET-A Density - Temperature relationship
(OP)
Is there a useable formula to correlate temperature to fuel density particularly Jet-A ? I am aware of the Coefficient of Thermal Expansion value of 999 x 10E-6 (ie .00099) per Deg C but reluctant to use this as there may be other variables to consider... Trying to plan airplane fuel requirements in gallons since most flight planning systems work in pounds.

i'm guessing that your coefficient is for volume change and that it is independent of the volume unit, ie .00999 gallons/gallon/degC

FYI, from what I understand these handbooks are available at a reasonable cost. How much and where from, I don't know as my previous employer bought them. But, they've got all sorts of conversion tables, physical properties, aircraft performance, engine performance, etc. data.

How did You get lucky enough to get a P&W Aeronautical Vestpocket Handboook?

The following link advertises them as part of a training course. You might be able to contact them and get a copy. $50 is a bit pricey though. I used to work for a UTC company (Sikorsky). I will check with my old cronies about getting a copy.
