Increasing The Thrust In FS9 Aircraft

Sun May 08, 2011 4:21 pm

Hello fellow flight-simmers,

I am am long time flight-simmer who has just started flying regularly again after a break of about a year or so. I usually fly the Overland Airbus and Boeing series aircraft for various different airlines. However recently I have acquired the Project Airbus A320. I find the model OK and I have downloaded a freeware panel for it so as not to use the default 734 one. The only problem I do have is that the aircraft is massively underpowered, it taxies OK on a low power setting however on the take-off roll it has the roll length of a fully loaded Jumbo and struggles to climb at all without stalling.

My question is, what bit of the aircraft cfg do I need to tweak to increase the thrust capabilities? I used to be quite proficient at tweaking cfg's a while back but have lost my touch.

Kind regards
EGPH

I get the feeling your problem is an incorrectly loaded aircraft. Lighten up the fuel/pax loads. No plane will ever fly with 100% pax and fuel. I've noticed that when switching planes FS will mess up the loads. There's no point messing with the CFG unless there is seriously something wrong, which I doubt is the case here.

Can't it be done by changing the static thrust data in the aircraft file?

[TurbineEngineData]
fuel_flow_gain = 0.002
bypass_ratio=6.00
inlet_area = 33.5757
rated_N2_rpm = 29920.000
static_thrust = 43734.000
afterburner_available = 0
reverser_available = 1

I just did it in FS9 with the default 737-400 (which I never use) I increased the thrust rating from 23,500 lbs each to 43,500. What a blast! With 20k lbs of fuel, I was climbing at 6000 fpm maintaining 260kts IAS. I got up to FL380 very quickly, turned off #2 engine, and still got an overspeed warning!!!

I agree, I have found the Project Airbus (realistically) unforgiving if overweight.

Thank you for your responses guys. It seems that shedding 50% of the pax and baggage weight is enough for the plane still to T/O and climb with a good fuel load (so that I can still do the LGW-TFS and LTN-SSH sectors in my EZY Airbus A320). Even then on a test flight from VCV-LAX I found that the plane thundered down the runway, kept level flight and descended and landed fine (on a very low weight and fuel setting) but struggled to climb at anything above 6 degrees nose up (about 1600 fpm). So I increased the static thrust which on the cfg had a warning DO NOT CHANGE on it and it seems to have kind of sorted the climb issue out!

Thanks again for all your help

Whats the point of making a plane less realistic?

I just tried that. Didn't know a Mooney could climb that fast

Easiest way is to increase the thrust_scalar.

Correct, changing the thrust scalar can give a 737 the power of Endevour and then some 
Did that and went so fast I hit a building on take off and the wingless fuselage went on flying to some 30.000 feet before falling back to earth
