lateral trim to compensate for asymetric loading?

Postby snippyfsxer » Mon May 17, 2010 8:07 am

When flying tiny little planes in the sim, I normally put two passengers up front to avoid the asymetric loads.  However, that is sort of cheating if you are flying alone.

So a plane like the Cherokee (at least in the sim, perhaps incorrectly), with only a pilot, wants to roll to the left.  I think this plane only has rudder trim.  So I can trim it out, for wings level, but then I'm flying at a slight crab angle.

Putting aside the issue of engine out situations in multi-engine planes, what is the proper use of Rudder, and or Aileron trim?  Should I simply be trying to level the wings, or should I be trying to center the ball too?  I never can manage to do both it seems.  I'm sort of embarrassed to ask because I've been simming for so damned long, it sounds like such a basic issue to not know...

You want the plane to fly straight so ball in the center.  Burn fuel off your side first.  Experience has shown that, in a wing low situation, it's mostly an aileron thing so bring wings level and apply whatever rudder, foot or trim, you need to keep it straight - usually not much.

I think you are talking about P-Factor.... where the downgoing blade (in a right-hand turning engine) produces more thrust than the upgoing blade.
