Concorde

[EHM-2309 Joshua]

I have installed Concorde, and the new flight dynamics, and the plane is unflyable. Even with autopilot on, it takes on a mind of its own. Please help...

Joshua,

What sim are you using? What weight and payload are set? I've used our Concorde for a long time in FS2004 with no problems so we may need a bit more detail to identify what the problem is that you're experiencing

[EHM-2309 Joshua]

Ok, I am using FS9 on XP. I have an empty plane with fuel in the wings set at 100% and in the main fuselage set at 85%. As reccomended in the Concorde SST file. I follow this file properly, not missing out any steps so that it should work. The CG is fine when I take off, and after about 1 minute of climb (just over 3500ft) it slowly starts to veer off to the left. It is the uncontrolable. I have the up-to-date flight dynamics, and by using both the FS2002 files, have managed to control this, however, they are the 2002 files, and not the 2004 files.

I'm not sure why the plane would veer off to the left - this would normally indicate uneven thrust from the engines or really strong winds, but wind doesn't normally affect Concorde at full thrust

When you say about both FS2002 files, do you mean the air file and aircraft cfg files? It's a while since I set up my Concorde so I'm not sure which files exactly you are referring to...

I'm not sure if this problem has happened before - have you searched the Forum for similar posts? At the moment I'm a bit puzzled as to what's causing this...

[EHM-2309 Joshua]

I have searched the forum for similar posts, and I did find one. That is where I got the idea to change the 2004 .cgf and .air files for the 2002 and ones.  This is one of the posts:

Joshua,

Have you tried the other FS2004 air file by Pedro Oliveira as I mentioned in that thread (2 years ago - no wonder I'd forgotten about it!)..?

[EHM-2309 Joshua]

I did as search for it on AVSIM, and used the link, and that file is not avaliable anymore. I used the 2002 .air file today, and managed to fly across most of the atlantic!! I ran out of fuel, and had to ditch it in the sea after a long descent!!! Also, when cruising, the plane has a pitch of about 7 degrees.

Hi Joshua !

I think I had similar issues with the Concorde but then I was able to fly her... it is funny because I do not remember these bugs from those days when the plane was inserted into the fleet. I did not had such problems when I spent enough time on the ground: needed for fuel balancing process, and also when I setted flight dynamics mode to "Easy" in the FS2004 settings. Nowadays I fly with "Difficult" settings and flying the Concorde is really hard with this settings.

[EHM-2309 Joshua]

ok, Concorde flies nicely now. A couple more questions, what should the fuel flow scaler be? mine is 1.35 at the moment. Also, how do you change the cruising pitch angle of the aircraft? or should it fly at about 7-10 degrees?

[EHM-1001 Robert]

It is not so easy.

The fuel flow scalar should be adjusted after everything is fine with the dynamics ! This will define your range. If you feel the range is too short, then decrease it with 1-2 tence.

The high pitch angle or AOA is a result of bad dynamics. Many parameters can effect to it, that is why the 2004 dynamics were released by Pedro to solve this problem. You could also try air-file from Libardo Guzman's brand new Concorde model. You can find it probably on AVSIM or FSPlanet.

[EHM-2309 Joshua]

I am trying the air file from Linrado Guzman's new concorde model now. I will get back to you on how it performs...

[EHM-2309 Joshua]

I have put the new air file in, and it works, fuel usage works fine with the 1.35 that the cfg file had already. Thanks for your help guys.

Best Regards,

Joshua

Glad you've managed to solve that problem Joshua I hope you enjoy your supersonic flights !
