Curious!

[waski37]

I have been noticing that when i start to taxi to the runway in any plane i fly, that when i switch to the outside view, i see the plane jumping and the front gear with smoke coming from it and the brakes are not applied.

has anyone else experienced this?
and what did you do to prevent it from happening?

Also my 747 when i start to takeoff, i don't hear any audible telling me V1 and rotate, is this common with this aircraft or is it something i'm not doing?

Yes, it is very annoying. Does it happen online? I found that the plane could jump into such a temper it crashed on the spot. I haven't experienced so much of the problem offline. I don't know of a way to cure the problem. Is it every runway or just a particular one? There are bugs in FS. (wow! )

Ever have that happen when sitting still? It's happened to me twice.

[Saitek]

Been there, had that.

I once had a plane that would put a mexican jumping bean to shame.
Usually if this is happening while stopped the problem could be the contact points for that airplane. When it does it while taxing it probably has to due with the elevation of the runway maybe? not sure on that one though. But if the contact points are in referance to a given elevation and the elevation changes for one reason or another than I  could see this happening. I have noticed in most cases it is where a taxy way crosses a runway. If the taxyways are made with AFCAD then there might be a slight elevation differance.

This has no cure-every(almost) simmer has experienced this problem.There are many explanations in sim community for that,but most believable to me is following:
When you change view to outside your machine has to load mesh(ground) and sometimes short delay may occure-so aircraft's wheels "loose" ground for a second...

[Saitek]

I believe as well as FS bugs, using downloaded planes that are "not quite done", maybe using FS2002 aircraft as well as contact points.
But I personally have experienced it more online - so.

I'm afraid there is really no cure. As sterk pointed out, there are many suggestions, but not really a hard answer.

It can be fixed.. but it takes a lot of trial and error with the gear contact points..

Static-cg-height.. static compression and compression ratios...

Careful !  It will tax your sanity !

That's panel specific.  I have a 777 panel that says these things :

Airspeed above 20 kts = "Airspeed Alive"

90-100 kts = "Vee One"

140-142kts = "Rotate"

if you mean the PMDG 747, then you should be able to hear the voices...

IF you go throught the takeoff ref page in the FMC and click the keys beside the total weight, V1, Vr and V2 values (that makes the FMC calculates those speeds for ya, real neat )

Some of my aircraft do this too.  I found a "quick" fix, before the aircraft crashes on the spot, just drop the flaps and then raise them again and all goes to "normal". This works for me, no idea if it is universal.

I believe the bounceing is just, as someone elce said, a delay in creating the ground mesh. I wouldent waste your time fixing something as minor as this  if you do crash, slew back in to place  no big deal.  As far as the V1 ect. I have never had those sound files and it is totally panel/gauge specific.  Take it from a long time FS'er  i have flown CFS CFS3 (terrible game engine) FS2k2,  FS2K4  (all microsoft, non-microsoft to folow) Secret Weapons of the Luffwaffe (oldie) Janes USAF, some F-16 sim, Janes ATF, and about 3 others i cant name and there are some things on simulators you have to come to accept and expect.  All good fun especally those little glitches to make life hard, or more fun.  ;)

-i wish you good flying and clear skys
