[A380 UPDATE] Your Ultimate Guide to Infinite Flight Fuel Burn + Fuel Calculator


Your Ultimate Guide to Infinite Flight Fuel Burn

Sometime in early 2021, I decided to start my most ambitious Infinite Flight related project to date. I was going to find a fuel burn profile for every airliner in the game, so that people could minimize the fuel they used as well as not accidentally pack too little and have to divert.

August came and went, and my subscription expired and I chose not to renew it. I didn’t finish the project. Over this summer, I decided to come back to it due to the semi-frequent “fuel burn” topic. Yes, I bought a month subscription and spent $10 to do less than an hour of flying on live servers just so I could finish this. I really hope this helps at least one person.


Fuel Calculator

In my previous fuel burn topics, I provided fuel burns with respect to load and altitude. This time, I have added a calculator too. Instructions will be in the follow-up post.


Disclaimers

I don’t have enough characters to write a full list but basically I’m not perfect, my numbers aren’t perfect, and I assume no responsibility for violations (but let me know if something is wrong).


Terminology

  • Game Fuel: the amount of time that Infinite Flight says you’ll get if you max out the fuel on an aircraft (also translated into a distance based on cruise speed).

  • MFR: maximum ferry range, the absolute maximum amount of time the aircraft can fly for without engine-off shenanigans (also translated into a distance based on cruise speed). Includes exactly zero reserves.

  • MPR: maximum practical range, the maximum amount of time the aircraft can fly for while carrying max passengers for airliners or max cargo for cargo planes (also translated into a distance based on cruise speed). Includes 5% contingency fuel, 30 minutes holding fuel, and 30 minutes diversion fuel.


Aircraft Included

This guide is mostly for airliners, so military aircraft as well as select general aviation and specialized aircraft are not included. I simply don’t have the expertise to even begin to measure fuel burn for these aircraft because there are so many variables that I don’t know. However, I suspect that the vast majority of you aren’t long hauling these aircraft anyways so this shouldn’t be a problem.

Airbus A321-200 [A321]

Fuel Capacity Tested Speed Game Fuel MFR MPR
55,609 lbs / 25,224 kgs M 0.80 9hr 46m / 4,430 nm 13hr 35m / 6,200 nm 10hr 00m / 4,540 nm

Flight Profile (East): FL290 (100%-0%)

Flight Profile (West): FL280 (100%-0%)

Additional Comments: The A321 has a bit of a broken fuel curve in which it doesn’t exactly matter what altitude you fly at. As long as you aren’t being egregious (like FL400 at 100% load), you will probably be well within margin of error. It also seems to be more efficient at M 0.80 when heavier and 0.78 when lighter.

Airbus A330-200(F) [A332]

Airbus A330-900neo [A339]

Fuel Capacity Tested Speed Game Fuel MFR MPR
245,313 lbs / 111,272 kgs M 0.82 24hr 11m / 11,390 nm 24hr 23m / 11,490 nm 15hr 49m / 7,410 nm

Flight Profile (East): FL290 (100%-81%), FL310 (80%-71%), FL330 (70%-61%), FL350 (60%-41%), FL370 (40%-31%), FL390 (30%-11%), FL410 (10%-0%)

Additional Comments: Interesting to note that the A339 presents little fuel efficiency advantage over the A333 (the 40 extra minutes of flight time comes from the added fuel capacity). The only benefit is a slightly higher load capacity, which means a lower load percentage with the same non-fuel weight which means slightly less burn with heavy non-fuel loads.

Airbus A340-600 [A346] (LEGACY)

Fuel Capacity Tested Speed Game Fuel MFR MPR
375,932 lbs / 170,520 kgs M 0.82 17hr 21m / 8,130 nm 18hr 02m / 8,470 nm 14hr 42m / 6,880 nm

Flight Profile (East): FL290 (100%-31%), FL310 (30%-0%)

Flight Profile (West): FL280 (100%-41%), FL300 (40%-21%), FL320 (20%-0%)

Additional Comments: Slight fuel advantage going west but not enough for me to make two different regressions for the calculator.

Airbus A350-900(ULR) [A359]

Fuel Capacity Tested Speed Game Fuel MFR MPR
285,499 lbs / 129,500 kgs M 0.85 22hr 19m / 10,900 nm 25hr 25m / 12,430 nm 18hr 17m / 8,910 nm

Flight Profile (East): FL290 (100%-51%), FL310 (50%-0%)

Flight Profile (West): FL280 (100%-31%), FL320 (30%-0%)

Additional Comments: I know most of you won’t want to fly your A350 this way so if you follow a more normal curve starting around FL330 and going up to FL410 and climbing linearly, plan to add about 500 pounds of additional fuel per flight hour.

Airbus A380-800 [A388]

Fuel Capacity Tested Speed Game Fuel MFR MPR
560,263 lbs / 254,131 kg M 0.85 22hr 11m / 10,840 nm 22hr 32m / 11,000 nm 17hr 55m / 8,730 nm

Flight Profile (East): FL350 (100%-91%), FL370 (90%-41%), FL410 (40%-11%), FL430 (10%-0%)

Flight Profile (West): FL360 (100%-81%), FL380 (80%-21%), FL420 (20%-0%)

Additional Comments: Be careful climbing, especially when heavy. Above FL320 you’ll probably need to be around 500 FPM maximum.

Flight Profile (East): FL290 (100%-0%)

Flight Profile (West): FL280 (100%-31%), FL300 (30%-0%)

Additional Comments: Using Flaps 10 saves a massive amount of fuel in a pinch.

Boeing 747-8 [B748]

Fuel Capacity Tested Speed Game Fuel MFR MPR
433,936 lbs / 196,830 kgs M 0.85 23hr 44m / 11,600 nm 21hr 06m / 10,300 nm (20hr 38m / 10,070 nm) 17hr 31m / 8,530 nm (17hr 01m / 8,280 nm)

Flight Profile (East): FL290 (100%-71%), FL310 (70%-41%), FL330 (40%-21%), FL350 (20%-0%)

Flight Profile (West): FL280 (100%-0%)

Additional Comments: This is the only aircraft in this guide that had such a big east/west discrepancy that I decided to do one calculator for each (for comparison, most other aircraft are within 5 minutes between their east and west profiles). It is likely that FL270 has the same effect as FL280, but that is below the Mach Transition so I chose not to include it. Eastern values are in parentheses.

Boeing 757-200 [B752]

Fuel Capacity Tested Speed Game Fuel MFR MPR
76,968 lbs / 34,912 kgs M 0.80 10hr 17m / 4,670 nm 11hr 23m / 5,180 nm 9hr 29m / 4,300 nm

Flight Profile (East): FL310 (100%-41%), FL390 (40%-21%), FL410 (20%-0%)

Flight Profile (West): FL300 (100%-71%), FL320 (70%-41%), FL400 (40%-0%)

Additional Comments: The middle altitudes aren’t bad either, just make sure you follow altitudes that are somewhat along the line between the higher loads and lower loads.

Additional Comments: This has got to be the most ridiculous fuel curve in the game. Everything is fine until you get to the lower weights. Then, the MD-11 enters this pocket where around 70% (ish) throttle it experiences a significant drop in fuel usage. This leads to some pretty insane numbers (as well as points where decreasing the weight actually increases fuel usage because it leaves the pocket). Flight times can be significantly increased (2-3 hours) by being more precise on the margins.

Additional Comments: Like the DC-10, I was expecting this to have the same numbers as its passenger counterpart. However, this is not the case. It doesn’t go into the same pocket that the passenger version does, which leads to it having a more normal fuel curve (albeit it burns quite a bit more than the passenger version even when its out of the pocket).

Step Climbing

One question that I wanted to make sure to answer while putting together this project was which aircraft need step climbing to be efficient. One of the loading screens says you should step climb for greater range, but how true is this?

For the purposes of this chart, I will assume that you have picked a good starting altitude. Just because an aircraft is in “Don’t Bother” doesn’t mean you can take it to FL410 at 100% load.

How To Download

  1. Use this link to open the spreadsheet in Google Sheets.

  2. If you have Microsoft Excel on your local machine, you can download the file from here and start using it.

  3. If you don’t have Microsoft Excel, you’ll need a Google Account.

  4. Hit “file” in the top left corner, and then “make a copy”.

  5. Follow the prompts until you have a non-read-only version in your Drive, which you can then use.

Fuel Calculator Instructions

  1. Input your zero fuel load (this is a percentage - not a weight in pounds or kilograms). To get this, load however many passengers and how much cargo you want without any fuel, and check the load percentage.

  2. Input your projected flight time obtained from SimBrief, converted into a decimal (for example: 1 hour 30 minutes is 1.5, 3 hours 12 minutes is 3.2). Since the age requirement here is 13, I hope you guys can handle this. SimBrief times are generally a little longer than Infinite Flight flight times, so this extra fuel will make up for the excessive fuel you use on your climb out.

  3. Fuel needed is (approximately) how much fuel you need to complete the flight. Please never take off with this load as there’s probably a good chance you won’t make it. Fuel with reserves adds an hour flight at 50% load worth of fuel. This will translate to an extra 45 minutes of flight time with most aircraft, which should be safe. I added a third section because I know a lot of you fly overnights where you don’t step climb.

I tried to make the calculator as usable as possible, but it isn’t idiot proof. Please use some common sense.

Note that all calculator values are simply based off trends and are not tested. So before you trust your account’s violation history on it, perhaps test it by bringing a little extra fuel and seeing how much you actually burn.

Closing Remarks

Honestly, this topic was long overdue but I’m glad I finally got it done. Doing all of this was tedious to say the least but I hope that the community appreciates it and finds it useful. Please do let me know if anything is mistyped in here or if my numbers are significantly off so that I can fix it.

Now I can retire in peace.
