Hi,
Thanks for that report.
I assume these were all tests on supposedly the SAME type of fuel (Jet A1 or whatever it might be called in the USA).
The report doesn't indicate the specification limits nor the expected range limits for most samples.
So were these 19 samples in spec?
Differences look considerable. So why such differences?
This supports my fuel quality is a "Black Art" proposition.
I wonder why vapour pressure, calorific value etc wasn't (aren't) checked?
If I was buying aviation fuel in vast quantities I would want to be sure that the stuff wasn't being "diluted" or in other words providing less bang (mpg in car speak) for my buck.
Interesting.
