how many gallons of gas would it take to cover a mile in an airplane?

Answer 1

There are too many variables here, we need more info.

Answer 2

this depends a lot on the type of airplane, the speed of the airplane, the load of the airplane, etc

its like asking about the gas mileage for a "vehicle"

a loaded semi going up hill at 70 mph will get very different gas mileage than a light hybrid on flat goin 30 mph

the text below describes a small plane that gets about 16 mile per gallon
----------------------------------------
The Young Eagles RV-6A airplane can carry 36 gallons of fuel. The engine uses 9 gallons per hour, which means we can fly for four hours. The airplane travels at about 150 miles per hour, so that means I could fly for 600 miles.

this site:http://www.eere.energy.gov/news/news_detail.cfm/news_id=9928

gives 44 passenger miles per gallon as a reasonable jet airliner rate

that means a 200 passenger jet would only average about 1/5 mile per gallon

Answer 3

Check this website out, it says that a Boeing 747 uses about 5 gallons of gas for one mile. There are a few other interesting facts on there too. I hope this is what you were looking for.

Answer 4

For each gallon of gas burned, the weight of the plane decreases which also decreases the fuel load.

Boeing probably is quoting an average number for one of its flights.

To be more specific, one may have to look at curves.
