Hey everyone. I’m doing a bit of research, and I wanted to see if anyone would have an answer.
Before you go down to to reply: this is not a topic about how to calculate how much fuel I need for a trip.
How is specific fuel burn calculated? Is there a formula?
I would imagine it goes something like: weight/thrust-headwind/N1
What factors are taken in to consideration? How much does air pressure (by changing altitude) affect fuel burn. And climbing?
