Regarding Fuel Consumption for four-engine aircraft (maybe two-engine aircraft as well) is it in total or is it per engine?   Capture.PNG   540.69KB   0 downloads

 

For example for this 747-400, its about 73k. Is it for all 4 engines its 73k, or each engine has a fuel consumption of 73k? 

 

 

Same can be said for the 777-200LR

Thank you in advance, and sorry if this is the wrong thread, I rarely post here  

 

Thanks and have a good day/night :-)

Total for the plane

You know I don’t really know how fuel consumption is calculated
All I know is that the faster the plane, although the plane has a slightly higher fuel flow but the fuel consumption is still the same.
Like how is it calculated in the first place

I feel like it should've been more clear on the fuel consumption because it makes it makes it somewhat unclear whether is it for each engine or total?.

It is obviously total.

You could have, for instance, tested the fuel bill for a 744 vs. a 77L.

This is the kind of basic and easy information gathering. 

 

Fuel consumption per mile is a simple matter of flow*time, where time = (stage length) / speed

 

Add seats to that calculation and you have fuel efficiency. 

 

It's all ridiculous of course, as you'll see things like the 737-400 having lower fuel burn than the -800. 

 

This is because the game calculates fuel flow based on specific fuel consumption at takeoff and at full thrust, imagining that these conditions hold for the entire flight. The concepts of L/D and even weight are far beyond the game's  purview.

I see, so the easiest way would be to test it out right?

 

 

 

 

 

 

 

Also thank you guys for your feedback!!

This is how you calculate it:

 

A - Fuel Flow (kg/hr)

from game

B - Fuel Flow (lbs/hr)

divide Fuel Flow by 2.2

C - Max Pax for the plane

from game

D - Speed (mph)

from game

 

Efficiency (lbs/pax/ 1000mi - lower is better)

 

B/C * 1000/D

 

This gives you an efficiency factor you can compare between planes, which indeed shows like Emperor noted that 734 is more efficient than 738
