Wilco Airbus incorrect fuel flow rates.

Recommended Posts

Good Evening Gents.

 

I currently having too low fuel flow issues with the wilco a330-300 , a340-300 and a340-600.

 

Basically the fuel flow rates are too low, and I keep landing after long flights with far too much fuel and get told off by my VA management !!!

 

Im using correct fuel figures/payload as im using the Real world pilots plogs.

 

Ive listed below the "fuel flow scaler" in the [GeneralEngineData] section of the aircraft.cfg for each for each aircraft.

 

I believe you can adjust this figure until you achieve the desired fuel burn rate for a "known" burn rate figure @ AUW/FL ISA.

 

So if some clever sole can help me with this it would be great.

 

 

A340-300

 

[GeneralEngineData]

engine_type=1

Engine.0= 0.0, -30.0, -2.500000

Engine.1= -10.0, -68.0, -2.500000

Engine.2= 0.00, 30.0, -2.500000

Engine.3= -10.0, 68.0, -2.500000

fuel_flow_scalar=0.82127

min_throttle_limit=-0.7

 

 

A340-600

 

[GeneralEngineData]

engine_type=1

Engine.0= 0.0, -30.0, -2.500000

Engine.1= -10.0, -68.0, -2.500000

Engine.2= 0.00, 30.0, -2.500000

Engine.3= -10.0, 68.0, -2.500000

fuel_flow_scalar=0.73

min_throttle_limit=-0.7

 

 

A330-300

 

[GeneralEngineData]

engine_type=1

Engine.0= 0.0, -28.5, -2.500000

Engine.1= 0.0, 28.5, -2.500000

fuel_flow_scalar=0.6175

min_throttle_limit=-0.7

Hi

 

I have some settings for the A340-300 aircraft.cfg you may want to try out:

 

Under Flight Tuning:

parasite_drag_scalar =1.15

induced_drag_scalar =1.35

elevator_effectiveness =0.8

aileron_effectiveness =0.6

 

Under TurbineEngineData:

inlet_area=28.51

static_thrust=34000.000000 (for A340-313 and -313X)

 

Under GeneralEngineData:

fuel_flow_scalar=0.76

 

Under jet_engine:

thrust_scalar = 1.00

 

Make a copy of the aircraft.cfg before doing anything to it. You should end up with an aircraft that will burn between ~6000 and ~8000kg, depending on cruise level. I hope you like these changes as much as I do.

 

One of the Gents :P
