Hi, since yesterday my King Air is hard to fly. After reaching hights about 8000 ft and speed is reaching the white arc, the bird begins to shiver/nick. I've made a small video:

Any idea for the reason of this fast movements? The AP also doesn't work on ALT or ALT SEL, the input will be ignored. :-(

That's an odd one.. Surface icing, prop ice maybe? Your gauges look normal... I've had the C90 up to 20,000 and never experienced anything like your video shows.. That is one rough ride you got going on there.

Is the AP switched ON?

Yeah looks like its fighting something wanting it to climb.

 

Start by loading a default Cessna "basic plane".

I had a issue when saving a default flight where some AP commands carried over to the plane and were on when loaded.

 

BTW- I always get a small "bunnyhop" just after I touch down. Its just like I hit a speedbump.

Are you using A2A's accufeel by any chance? If so disable it :)

Mmmmm interesting video as my King Air did that too. I have only done one quick flight, and at the time thought maybe it was a sort of built in overspeed warning (so to speak). I think my Turbine Duke does somethig similar if I overspeed, no? Anyway shortly after my plane got the shakes I got the red overspeed warning in the lower right corner of my screen. Then when I slowed the speeds down I thought the shakes went away, but I could be wrong.

 

I do have the Accufeel thing, and will try again with that off.

Disable any WX you have, also make sure FS isn;t loading up an old metar file it has downloaded...

Rossdh good idea.

 

The accusim prog has created some wierd effects mainly just as you stated. I am not looking at it now but turn it off and /or move the stall/buffet sliders full right. The Asoft F-16 goes through a simular bounce even way above its stall speed since its not accurately set by the sliders.

I did two flights tonite with the Accufeel turned off. The shakes were gone and the flights were smooth, even when I intentionally overspeeded. Based on that it appears the Accufeel was causing a problem.

 

Did discover a new problem though, after my flight is finished and I try to exit out to the free flight menu, FSX crashes to the desktop, and the error report window pops up. This happened on all 3 of my flights so far.

YES! Accufeel has wrong settings for max Airspeed (122 kts) which causes the C90 to vibrate. I've dissabled Accufeel for the King Air and now everything works fine. THANKS for your help, guys!!

Thanks for that news, I will too.

Why don't you just correct the setting???

I will do that. Yesterday there was only time for a short checkride ;-).

My question too.. Its a shame to swiotch something of if it can be corrected in C90.. accusim is not the problem here. the file in C90 is wrong.

accusim is not the problem here. the file in C90 is wrong.

 

Hey, the troll is still here....amazing
