Default Steering on the taxiway

Is it better to use just the rudder or differential braking to turn on
taxiways? I understand that steering mechanisms vary considerably
from one aircraft to another, but I'm still curious. In this case,
I'm wondering about a Baron 58, the aircraft I fly in my sim (most of
the time).

I note when taxiing that the aircraft seems to oversteer, especially
as speed increases. That is, I'll move the rudder to straighten out
on the centerline of the taxiway, but the aircraft still continues to
drift slightly in the turn and overshoots the centerline. Is this the
way the real aircraft works? If so, what causes it? I should think
that if the rudder pedals turn the nose wheel directly, it would be
hard to overshoot unless the nose wheel actually skids or something
(?). This isn't happening at high speed, it's like 16 knots or so (or
does that count as high taxiway speed?).

The Baron is a twin, you also have differential power.

Is it practical/desirable to use it for steering?

Unfortunately it is very awkward to adjust the throttles separately in
a sim, so I've never tried this type of steering.

Depending on the size of the aircraft and the engines, only small
increases/decreases (+/- 100 rpm) in power are necessary if applied at
the correct times.

So why are you trying to tell him how to fly a simulator?

I don't get it.

Yes, it is.

Hmmm. Let me guess ... you don't have a full throttle quadrant in addition
to your yoke and rudder pedals (hopefully with brakes).

Without all of that/those, I don't see how you hope to simulate any
particular type of aircraft.

Just a single throttle. The occasions where I might need separate
throttle controls are so rare that they don't justify the expense of a
full dual set of throttles. For things like single-engine failures, I
pause the sim to reset throttles or feather props or whatever.

Perhaps, since you are not really using it as a simulation in preparation
for a flight. OTOH, you found one.

For things like single-engine failures, I
pause the sim to reset throttles or feather props or whatever.


Thus simulating nothing.

Using a game, I don't see how he can hope to accurately simulate anything, other
than entertainment.

It's actually 18 TAS, not IAS, that is correct.
