Concorde X nose wheel bouncing during takeoff and TLA

Featured Replies

I'm just wondering if this is normal with 2 different questions.....

 

Seems like the nose of the plane is light a lot of the time. The nose will lift off the runway near 100kts or bounce a few times off the runway and tire screech near and past this speed. I can avoid this lift off and further down the runway with elevator down but this doesn't seem proper.

 

Also, after the takeoff count down is done you are suppose to set the throttle to the bugged TLA 15.5 degrees, how do I do this? Hitting F1 seems to shut throttle fully off.

I think the tutorial flight has the answer to your second question.

Best regards, Fritz ESSONO

Your first question has me wondering if you're setting the usual correct value of -2.5 trim, and not +2.5 trim... this would definitely cause the issues you mention in the first question, set the trim to nose down -2.5.

 

Edit: I should also mention that on the FSLabs site you'll find this file, try it out!

As for the second question, I'm not sure how to help as I am strictly a Concorde pilot and not the FE, the vFE feature is one I rely on to do all of those after takeoff things while I'm busy hand flying the aircraft up in to the the flight levels... make sure all of his features are checked and just watch what he does after takeoff if you can find the time!

 

Best of luck flying 'Pointy!

I would not be asking here if I could find this in any of the manuals. Feel free to reference me the page number.

 

Edit: NM. Found it finally in the keyboard settings. Seems its a special keyboard command, Ctrl+F5 will set the throttles to TLA.

 

Far as the nose bouncing, yes, I have -2.50 set. Is it always suppose to be set to -2.50 for all takeoffs or will this value vary depending on different flight parameters? I am NOT doing the default London to NY trip btw.

Could it be headwind? I took off OK with 6 knots just now.

It's a function of the CG in place.

On the bouncing. What's your CG? Are you using some tools like Accufeel with Concorde? Can you run her on a test with that one disabled?

 

Maybe she just reacts to your user name. ^_^ Just kidding.

I'm using the Virtual Flight Engineer, shouldn't the CG be totally hands off to me and automatically set by the VFE for every takeoff/flight? I thought that was his main job, to manage plane balance via payload and fuel at all times.

 

Aside, I also thought Accufeel was a visual/audio thing and didn't alter actual plane physics at all.

You are right, Roger does a lot of things, e.g. handling the fuel to achieve a proper CG for each phase. But you had it about the takeoff trim and, by this, you would read the TO CG from the FSL payload dialogue and then trim by using the above chart.

 

As for Accufeel, it can't hurt to click it off for a test flight. It adds physics too, so the shaking of the plane for example happens trough AF. Maybe this influences your TO run and leads to the bumping.
