Time acceleration, A/P and PSS 777 (also PMDG)

Featured Replies

Hi all

 

I like to do atlantic crossings, but when at cruis altitude, I put on acceleration. At 8x all is fine, but above the plane starts going up and down, more violent the longer I leave it that way.

 

Is there any way this can be solved?

 

Thanks!

Hi,

 

proboably you will get more precise answer, with my add-on's all freeware, ifly747, simmer a320, with accelerate 4x, even 2x, planes are totally "insane", so I think it's even not made to run under higher accelerations!

 

cheers

I believe that Microsoft states autopilots don't work at high rates. The more complex the aircraft the less they are likjely to work even at lower frame rates.

 

It's a fundamental restrication. At, say, 16x you are expecting your PC to do 16x as much computation in the same time.

Not all autopilots are that stable for high sim rates; PSS being precisely some the worst offenders. Maybe tweaking the autopilot constants in the FDE would solve this, specially those related to pitch (max pitch, max pitch velocity and max pitch acceleration). You may check this thread: http://forum.avsim.n...-777-fde-tweak/

 

Hope this helps.

Damn, too bad. I'll have a look at the tweak though.

 

Thanks anyway!

Or just fly real time and watch TV!

Haha!

 

Although I like realism, letting my laptop push itself to the top for 8 hours is a bit too much.
