In real world it's normal that the plane wants to turn left.
You have to use the rudder (foot pedals) to keep the plane on the runway.

Again, this happens also on a real plane.

To overcome this problem in the simulator is to decrease the realism
settings:
Shift the P-factor slide to the left (Menu Aircraft ->Realism
Settings ->Flight model -> P-factor)

Now you shouldn't have the problem anymore.

Succes...

Ok. Now how do you do that in Real Life? 8^)

Hmmm ... I don't recall any plane I ever flew wanting to turn left
under normal conditions (admittedly, that's only two -- I ran out of
$$ before I got my pilot's license). I remember my instructor showing
me how stable the aircraft was my first lesson -- got it up, let go of
the controls, and it just kept going straight and level (a Cessna 152,
#N7603U if I recall).

The torque from the prop does impart a rotation force (not actually a
turning force), but if I recall the manufacturers counter at least
some of that with built-in corrections in the airframe. They can't
counter 100%, as torque changes as the throttle varies.

More advanced aircraft have additional trims, besides elevator, to
handle any unusual forces. I don't know if the trim gives you enough
correction to compensate for losing a critical engine in a twin,
however.

I've never noticed this in FS, but I usually fly the larger aircraft
and use autopilot for the most part. If the plane your flying does,
in fact, have horizontal trim you might try that.

A prop plane wants to turn left when it's on the runway gaining speed in the
beginning.
This is normal. Once airborne, this effect decreases.
In the FS2000 it's called the P-factor. Decrease your realism settings if
you dont like it.
Or use the rudder.

Use rudder trim so you don't have to constantly depress the rudder pedal.
Same as you should be doing in FS ;o)

Sure, if your aircraft has rudder trim!

But in a C172, that's be your right foot, right? 8^)

You probably never put your feet on the pedals during climb or take-off. The
left turning tendency is obvious. The way to compensate is with right
rudder.
The reason for the left turning tendancy is that when you have a large angle
of attack, the propellor takes a bigger bite of air on the right decending
side, than the left raising side, so there is greater force being exerted on
the right side of the prop. Hence a turn to the left. Add to this the torque
of the prop and engine, also the vortex from the prop hitting the tail. The
torque effect is slightly offset by the rigging and a tab on the tail that
gives a slight correction to the right. But, during climb or take-off, you
must use right rudder.

In the realism settings there is a setting for AutoRudder. Click on it if
you want the program to automatically compensate.
