It has been suggested over the years, for the sake of realism, that
Microsoft should also model Interior Turbulence in the virtual cockpit of
FS2004. This never happened.

As many suggested, the virtual cockpit should not stay perfectly still all
the time, it should shake and jerk around just a little especially when
hitting turbulence. Also it should be a little shaky when pulling a high G
maneuver, in fact you should be able to tell how many G-s you are pulling
just by looking how badly your instrument panel jerks during a snap turn.

A320 Pilot in Command has a similar feature that they call: "Interior
Turbulance and turning effects" Allowing desktop aviators to watch their
flight panels shudder and shake during turbulence and heavy turns for the
first time. Everything in the pilot's field of view will move in response to
the aircraft's motion, whether in the cockpit or outside the windshield. See
it - feel it - and enjoy the ride.

Other simulators that have such a feature are Air Warrior since 1997!

Flying in turbulence with the present "static" cockipt, is unreal. Since
Microsoft has difficulty implementing this realsim feature, is there any way
to modify the panel configulation file in order to add such effect? I
searched the web (Avsim / Flightsim) for any add-on, to no avail.

Are there any programmers out there that can write such add-on? I'll be the
first one to buy it.
