Hello fellow flightsimmers,

 

Joined this forum in order to maybe get a bit of help with a problem I am having with the Project Airbus A320 flight dynamics. I am a long term flight sim user whose flown many different aircraft types over the years and managed to alter the Aircraft CFGs to make the flight experience that much more realistic. This however has me stumped.

 

After downloading the aforementioned aircraft from AVSIM and taking it for a spin I realised the engine performance is very strange. At idle power on the ground the aircraft actually taxies (and can reach a good speed if allowed to go on), I have sorted this out with other aircarft in the past by reducing the idle thrust scalar on the cfg file so that's not really an issue. However from being over powered on the ground, it lacks in the air. On a full power take-off the aircraft takes a good while to get up to 130-140 kts rotate speed (much longer than the Overland/SMS version I'm more used to). On the climb the aircraft struggles to gain airspeed at vertical speeds of more than 1600 feet per min. If climbed to cruising altitude at 1800 fpm the aircraft will start to actually lose airspeed at around 10,000ft and will struggle even to climb at 1400 fpm at altitudes above 18,000 ft. Does anyone know how to fix this problem as it has me properly perplexed?

 

Thanks in advance for any help offered

Well, have you tried with the stock Project Airbus FDE? I use it with the Wilco panel, and I have no problems at all (well, I edited it, but not in the ground idle regime). But if you insist to modify the FDE, edit the values for low Mach and low N1 in table 1506 of the airfile.

 

Hope this helps.

I have the same difficulty,i really struggle to get the airplane to perform and if not careful it stalls too easily,the A319 does the same! :angry:

I can't get the stock Project Airbus A320 to work, I have downloaded it and put it into my Aircraft folder but it doesn't show up. Doesn't help that the Read Me file is far from idiot proof!!

Which panel are you using?

Tony,

 

Although the overland and project airbus models are simplified here are a few things to keep in mind.

 

Unless near max take of weight the real aircraft will happily taxi and accelarate on idle thrust, you can even taxi in on one engine with near idle thrust at light weights. This is the same for nearly all modern Jets.

 

On the A320 you actually have to be carefull not to overheat the brakes whilst trying to keep it from accelerating.

 

V speeds, acceleration and climb perfomance is based on a huge number of factors, even on simplified FS models. Ambient conditions/gross weight and even CG will affect how the aircraft performs.

 

On the real bus you initially climb at a speed called green dot (clean speed) eventually accelarate to your initial climb speed and use OPEN climb or managed climb to get to cruise safely and efficiantly. All of this is based on carefully calculated gross weight and weight and balance (CG)

 

Since your addon most likely doesn't provide any form of OPEN/managed Climb or performance planning, you need to ensure you accelarate the aircraft correctly in the first segments of the climb and in your case use the basic mode 'vertical speed' correctly.

 

There is a reason the real aircraft is not climbed in vertical speed. If it is done wrong you can easily get the aircraft into a bad situation, especially if you are not using the correct take off or climb speeds, and just randomly adding fuel pax and cargo.

 

Bottom line is don't be too quick to judge the flight model, it is likely pilot technique and a lack of the proper onboard tools to operate the aircraft correctly.
