What's the Best Way to Adjust Weight to Simulate Fuel Burn?

I’d like to start simulating fuel burn during my flights on the Expert Server.
I’m worried about disrupting Live.
I don’t want to leave the flight to change the weight settings too often. I also don’t want to create network issues and loose connection. Disappearing and re-appearing might also confuse ATC and other pilots.
So what would be the best way to go about this?
Advise would be appreciated.

Maybe once you reach cruise and turn final adjust it.

I change my fuel quantity periodically during my flight.


I just leave everything at minimum. 😅

Changing ur weight on live doesn’t make u go offline, leaving the app to go calculate the weight could get u offline. Also I just change my weight to landing weight right before I start my final descent

Fuel consumption ratio This has the fuel burn ratio in US Gallons to nautical mile travelled. Multiply the given number by your desired distance (within an aircraft’s actual range capability) then multiply that by 3.


I only adjust the fuel weight once on a flight. Normally this is about 10nm from TOD so still far enough away not to interfere withbATC or other traffic as usually around FL340+ and 130nm from landing

Thanks!! Bookmarked!!

It’s in Gallons.
How do I get the amount of kg I have to reduce the fuel with?

You multiply by 3 to convert from US gallons to kg.

This is a conversion chart link


I’m always reluctant to leave the flight.
Is it true that ATC commands come through even when you’re on the Weight & Balance screen?
So just to make sure; this won’t interrupt the flight in any way?

Ah, OK! I didn’t get that. Sorry.

WOW! Looks complicated!

I’m going to try to figure it out.


So, let’s see if get this.

Let’s use the 777-300ER.

The list states 777-300ER- 6.49796472

6.5 x 3 is 19.5 kg per nm

When I’m flying a distance of 100nm, I have to reduce the weight by 1,950 kg?

thar is correct. On longer flights you want to keep it as close as possible to the exact fuel burn ratio when multiplying. You will see a larger fuel burn difference the longer you go, obviously. The ones that have Confirmed MTOW means that the maximum amount of fuel is compliant below the MTOW. The 787’s MTOW in IF are incorrect.

That’s what makes it easy to do 10,000nmi flight though.

I always try to make sure I am well away from ATC or other aircraft and make the change quickly so I don’t ’ vanish’ for any length of time.

At moment I don’t do anything too complicated, set weight to HEAVY before pushback and then before TOD quickly reduce the fuel so to be at s landing weight.

Am going to start to be a bit more scientific by setting my fuel weight at start to a reserved amount ( 1.5 hrs burn) plus expected length of flight + 10%. With current flights this should still be below MLW!

I have the average fuel burn per min for most of the Qantas Virtual fleet and will post those later on.

Example of fuel burn per min:

B717 =35kg per min

DASH 8 = 24 kg per min

a320 = 42 Kg per min

Am going to start each flight with a min of 90 mins of fuel on board and then add expected fuel for the flight. That will be the tricky bit to work out how long a flight will be …part of the fun!

I think so too!
