   try out the FAA Circulars : here is a link.

   one of those advisory circulars has an approx. estimation for fuel consumption

   BTW for each model u gotta try out the aircraft manul , & not all of them are free online

   Your numbers are off a modest.

   A321 runs like 8000 gallons to place a stop to the US.

   Jet A is 0.8075 density, or about 6.74 lb/gal.

   Upshot is about 56 seat-miles per gallon. Its probably about 15% privileged than this at an efficient cruise speed.

   Typical small piston powered aircraft do about 1/2 this on Avgas. Bizjets are far of poorer quality than this.

   Here’s a link to give some approximate comparisons. Using the confirmed array vs. fuel room is very approximate mode; much fuel is used on the ground, all owing to climb, etc. Also, here are set aside requirements that are not commonly used in travel. Wind also makes a difference.

   Aircraft manuals have fuel consumption charts based on consequence, temp, height, and speed. Compiling real fuel consumption numbers is tiresome task. Many manuals are unfilled on line if you look ample; be aware that you need to assess weights and know the number passenger seats – most have numerous configurations.

   Another possible deal with is to assemble jet reported seat-miles and equate to fuel burned. While this averages across the fleet, the numbers between difference aircraft are liable sweet accurate, with bestow and better equipment having an benefit.

   well if its 150 mpg then it would be 150/8 miles per lb. in view of the fact that its 8 lbs per gallon
