Fuel Calculations

[SkyBarca]

Everything on the MFD regarding fuel is correct with the exception of the flightplan page.  It calculates the fuel use correctly, just not the actual fuel quantity.  It always seems to show, at the start, only the fuel on board when the aircraft was loaded in.  Not reflecting any fuel added after the aircraft loads into the sim.

Is there some page I am missing on the MFD to adjust the fuel so that it matches what the rest of the readouts show?  Fuel gauges, fuel page, both correct.

You need to adjust the fuel amount within the G1000, after you refuel or load the aircraft. There is a distinct fuel gauge, but as for flight planning, you need to adjust it manual to reflect the current fuel state. As remember it should be at the system page of the MFD. The most left lower softkey and than there should be some softkey for fuel increase and decrease.

I've been to that page, but it shows the correct amount of fuel.  I also can't find any way to change the amount.

Sorry I was mistaken. My above hint does not work with the TBM. It works on other G1000 aircraft 

So the fuel state in the flight planning page might be a bug with laminar.

[SkyBarca]

Looks like it was fixed in the recent patch.  May have been calculating in liters not gallons.

[SkyBarca]

This is actually still an issue.  The in flight calculations are based off of the amount of fuel the aircraft has when it loads into the sim.  Not the amount that you fill from the payload screen.

I have the same problem

Hi,

the same here - wrong calculation:

I have 1hr flight to go , 200 USG FOB, 58 USG FF and at destination I can expect -7 USG

Devs please take a look into this bug.

Thank you

[xpst]

Hmmm, I looked at all my G1000 docs (X-plane, Gamin, and Socata !), but in the sim I can't get the calculation to display.

How do you see it ?

(Note, I was on the ground, engine off, that may be wrong)

Thanks for any hints... !

Set view/wide in flt plan mode.

Aaarg, there it is. And now I see it in the manual too. Thank you !

[SkyBarca]

Still a problem for me as well.

[iamfallen]

I have this issue as well. I thought it was something I was doing since I am still learning the plan and the G1000. Is this a Laminar issue or something in the TBM?

[Goran_M]

Fixed and should be in the next update

[iamfallen]

Great news. Thanks for the hard work.

The last build 1.1.8 shows the same issue about the fuel remaining..

thankfully we do calculations of fuel, but thats a nice thing to have....

I like to adventure in the deep and far NAT on a single engine turboprop and it a nice to have when you have 50Kts headwind and you need to confirm if could reach your destination.

Cheers!!!

Hello everyone,

Like @jvp89 I still have the same issue in 1.1.8.

Wouldn't it be a "workaround" to put the Fuel into a config file, before i start the sim?

Maybe the Fuel state is given in the TBM900.acf. At least there is a section

PROPERTIES_BEGIN
P _cgpt/0/_name empty craft
P _cgpt/0/_w_max 4581.200195312
P _cgpt/0/_w_now 4581.200195312
P _cgpt/0/_w_test 4581.204589844
P _cgpt/0/_z_ref 14.300000191
P _cgpt/1/_name fuel tank #1
P _cgpt/1/_w_max 1005.299987793
P _cgpt/1/_w_now 1005.300048828
P _cgpt/1/_w_test 0.0
P _cgpt/1/_z_ref 14.300000191
P _cgpt/10/_w_max 0.0

So it would be possible to make the Flight Planing after that insert the right amount of Fuel into the acf, and than the Fuel calculation should be correct. Or am I missing something? 

[kityatyi]

It's still an issue. I am wondering when will this fix be released. 

[matchball]

Still an issue. Could this be fixed? Would make my flights less nervous when MFD would not be giving me neg values for arrival fuel. I haven't done much research about this, but I at least use the "resume last flight" (if the reason it has not been fixed is that devs havent been able to repro).

Any news on the issue? I'm on v1.1.12 and it seems the issue is still present.

There is nothing Hot Start can do about this as it is an issue with X-Plane. You see the G1000 in the Hot Start TBM 900 is in essence the default X-Plane 1000 the developer simply customized the X-Plane 1000 to reflect the G1000 found in the real aircraft. You can file a bug report here, but keep in mind Laminar Research are currently busy with the 11.50 beta, so it might be a while before they get around to fixing it (if ever).

On some Planes there are buttons in the G1000 where you can adjust the fuel load

[Marius_B]

This COVID lockdown I took the Hotstart TBM around the world in X-Plane 11 

25000nm (47000km), 2 weeks time, but it was nice!

You can confidently plan the fuel for your trips at an average of 60gph, 300knots speed, roughly 1500nm between refuels (depending on the winds), so if you are full, you can fly 5 hours without problems

Had to pay a visit to LFBT - Tarbes, France, the real TBM factory, Daher - Socata
