I’ve noticed that the aircraft has a very powerful tendency to pitch down, especially during landing, which makes it flying very difficult.
All of my trim’s are centered, flaps are 30, and I approach around 100 knots. Yet I am pulling up on the stick, hard, for the entire approach. If I let go of the controls for just a couple of seconds, it would be catastropic.
I’ve been following the checklists as best I can, but am still very new to this aircraft.
Why is your stab trim centered?
You should simply use trim until you can remove the hands from the yoke without your PC-12 changing its pitch attitude.
Exactly. The PC-12 is no different to other aircraft in that regard. If you are having to keep holding flight controls with some force then use the trim to get rid of that.
I usually land with the stab trim one line above horizontal.
Trim depends on weight, CG, approach speed and flap setting.
Without knowing the above, it doesn’t really help, but thanx for trying to help 
Someone asked about this in the discord, apparently it’s normal for the aircraft to have a lot of trim up in approach config. The pilot flying the PC-12 IRL that helped them develop showed a RL photo of the trim on approach, it was indeed over 1 bar up from center.
I am aware of that, but I find that in most configurations my trim is well above neutral. The TS stated that his trims were centered, so I just wanted to give a rough indication of what is normal in my experience.
I don’t really understand why there are questions at all about how much nose up/down trim is required.
As long as I don’t hit the up/down stop I don’t care at what position the trim is, neither in the sim, nor IRL.
Same run away trim problem. even after centering the trim. Any under idea of what the issue can be ?
Nobody wrote about a trim runawy?!?
If trim is moving on it’s own, either the AP is engaged or a assistance or AI is enabled.
I have an issue in that the electric trin via the bravo yoke does not work, it works on all other types of aircraft, Is this a known issue and is there a remedy fiore this problem.
Just gone to SWS website and downloaded update, will see if this works.
Still no joy with the yoke trim.
just encountered this bug as well. during low speed flight on final with full flaps the plane becomes ■■■■ near unflyable. 90% of my joystick movement aft the plane hardly responds, but in that final 10% (almost full back in your lap) the plane then noses up very sharply, with almost no control in between those two extremes.
I know this is an actual issue because I tried the same approach using ILS autopilot and the AP also could not maintain a normal approach as the nose-down-force was too strong for it to overcome or trim out and the plane wanted to nose-dive into the earth.
I am a seasoned sim pilot as well as an IRL GA pilot and trust me this is not normal behavior.
There must be other folks who have experienced this?
When I come out of Ap to land the trim goes beserk… it seems to change uncontrollably flying all the way up from 100% to -100% with minor touches. Is this a setting its bug?
