Hi there,

 

I'm mostly a heavy iron and really small GA flyer, although IRL I'm a low time PPL. Lucky me I have not experienced any of the problems others experienced, and I do feel particularly bad for those who purchased but can't activate. Hang in there, this bird is worth the wait!!

 

Yesterday, for the first time in my 15+ years simming, I've experienced my aircraft flying croocket, it looked and felt like it was flying left wing low (or right wing high) during cruise. Winds weren't too stron, I was on autopilot with YD engaged.

 

Then I found out during some research that this bird requires aileron/and or rudder trim while operating on AP, is that true? I know IRL some turboprops require that but I don't think I've ever seen it modeled in fsx, but I could be wrong.

 

If anyone has more info (I have not read through the whole documentation yet) I'd appreciate it.

 

This bird will bring thousands of hours of joy, can't wait to fire it up again.

 

Cheers,

Pete

This fascinates me too Pete. To be honest, I wasn't aware that some turboprops require trimming despite the fact that the AP is engaged.

 

Seems weird in regard to a modern aircraft and modern autopilot.

I noticed that too,

 

I gather that the (real world) ATR is similar. A friend who flies them said each one in his fleet has subtle differences in how it flies. Once in the cruise, each aircraft needs to be trimmed slightly (and uniquely!) in roll and pitch axes to center the ball and keep it all level.

 

Frankly I like it. It adds to the general sense of immersion.

Maybe when you activated the auto pilot it was out of trim?

Yes, this trimming requirement is really nice.

My question is about plane tilting during taxi.

During taxi even i make sharp turn, plane is rock solid and do not tilt even a bit, is it realistic ?

Unlike the ATR that has a close wheel base and tends to sway if turns are made too sharply, the Dash 8's main gear sits under the engine nacelles which allows for better ground handling.

A minor annoyance when flying the Q400 is that the Yaw Damper has only limited governance over the rudder, which means that the rudder has to be trimmed manually on every change in aircraft pitch or engine power setting.  So one will find that minor corrections need to be made through different phases of flight.

How I can know when apply trim? A good tutorial is needed!

 

I love PMDG for the quality of their products but too for the quality of their documentation manuals and tutorials...

You need to apply trim on take off, and adjust through different modes of flight. It's not something that can be documented easily, it's something you need to tweak/adjust as you go.

I figured this out myself tonight; while at cruise I had noticed my plane not flying level as well, and was about to come here to check to see if there were any posts about it, when I recalled reading somewhere (in the tutorial flight perhaps?) about trimming the aircraft and applied a bit of rudder trim which leveled it out nicely.  Neat stuff.

Yes but I look for rudder trim...

They don't have counteracting props so when you add or reduce power the aircraft will yaw left or right. It yaws but there will be no rolling tendency..

That's exactly why I love this "annoyance", just adds wonderfully to your Q400's realism - what a superior product!!!

Just monitor the PFD and look for the "ball" on top of the triangle pointer - keep it centered.

Above the ADI on the PFD is a slip / turn coordinator.

 

Just use this to apply trim as required.

Precisely, and that works like a charm. I have rudder trim mapped (via FSUIPC) to one of my hat swithes on my CH yoke, and trimming rudder has become easy.
