Fuel Flow settings (cockpit ini) and fuel usage

[+Cliff7600 1,120]

Hi

I'm asking for your expertise about fuel usage (easy/normal/hard mode) and calibration of the fuel flow gauge in the cockpit.

Has anybody ever tried to precisely tune the fuel flow gauge, with success, or with difficulties, or never made it and gave up ?
Because I'm really searching the way to do that and I encounter some difficulties I barely understand (what is 1.0 ? for example lol)

And then I remembered that the stock terrains are scalled down compared to reality, and now I wonder if the fuel usage set to hard is proportionaly increased, to keep the ratio in max range.

On many planes (all of them) I never had the real endurance in time corresponding to the manufacturer values.
And now that I count every pound used in a minute to calibrate the damn gauge in pounds per hour, I realise there's no way to have a realistic autonomy (in time).
I barely fly 1 hour yet I was supposed to have fuel for almost 2 hours.
So I decreased the MachTable values and obtained more endurance but lost the top speed and ceiling.

I set the fuel usage to "normal" and the indicated fuel flow figures are way more close to 'reality'.
Does that mean that fuel usage set to hard is keeping the range but alter the fuel flow in the process ?

Thanks

Fuel usage..  uhhm it could be

Easy - you wont run out of fuel

Normal  -  halfs the fuel consumption

Hard  -  fuel consumption as set in the data

Could be that TK had something on that on TW forum

And the map size - thats just to make the map/distances to fly smaller/shorter to speed up gameplay.. it has no effect on how the planes function.

 

Yes, Ive done the fuel gauge setup a few times.

Ill have to find my notes to be sure, but its like this:

The Value= entry is lb (or kg as set by ValueUnit=) per second

For example, you have a fuel flow scale with a max flow rate mark of 10000 lb/h

To have the entry for the 10000 lb/h mark, you divide 10000 by 60 = lb/h, then again by 60 = lb/s  for the Value=

Example from TW  A-7E cockpit ini

[FuelFlowIndicator]
Type=FUEL_FLOW_INDICATOR
NodeName=needle_fuelflow
MovementType=ROTATION_Y
ValueUnit=LB
Set[01].Position=-222.10
Set[01].Value=0.083 <------------ 300 lb/h
Set[02].Position=-15.50
Set[02].Value=1.389 <------------ 5000 lb/h
Set[03].Position=46.10
Set[03].Value=4.167 <------------- 15000 lb/h

Its a non-linear scale - values set for each range of the scale

Ok thanks, I'll try it.

For the hard setting = fuel consumption as set in the data, I still have a doubt after counting how much fuel was burnt in one minute for a given throttle position.
But it could be the data values that are too high, got to check that also.

Ok I found what was wrong.

Fuel usage is as Crusader told :
- "normal" is half the consumption
- "hard" is the consumption as set in the data ini file

The point I was missing is the unit used by default is the KG.
In the A-7 example "ValueUnit=LB" is indicated but when the ValueUnit entry is missing the game counts by KG per second.
All my tests was 2.2 wrong...

So for example, the TMF F-14 should have in the cockpit ini file :

[FuelFlowIndicator1]
Type=FUEL_FLOW_INDICATOR
NodeName=gauge5
ItemNumber=1
MovementType=ANIMATION
AnimationID=7
Set[01].Position=0.0
Set[01].Value=0.0
Set[02].Position=1.0
Set[02].Value=3.611
ValueUnit=LB

[FuelFlowIndicator2]
Type=FUEL_FLOW_INDICATOR
NodeName=gauge6
ItemNumber=2
MovementType=ANIMATION
AnimationID=8
Set[01].Position=0.0
Set[01].Value=0.0
Set[02].Position=1.0
Set[02].Value=3.611
ValueUnit=LB

and then the counting is right.

Thanks again !
