Physics-
The physics options are quite useful in fine-tuning the items applicable to the physics
of your simulated aircraft.
Airplane Physics Quality-
This setting determines the detail level of physics utilized for the airplanes in
the simulation. When the physics level is adjusted to the highest setting, the
simulation performs the aircraft calculations more accurately and more
frequently. Unless you are running the simulation on an older, slower PC, we
suggest using either the 'high' or 'highest' settings. Lowering the physics level
will reduce the quality and detail level used in the simulation, thereby allowing
the simulation to run at a faster rate on slower PC's.
To alter the physics options, click on the value indicated in the column to the
right of the Airplane Physics Quality name. Using either the up/down arrow
keys on the keyboard, or the mouse, select the level for your simulation from
the pull-down list. If using the up/down arrow keys, press Enter to finalize
your selection.
Helicopter Physics Quality-
This setting determines the detail level of physics utilized for the helicopters in
the simulation. When the physics level is adjusted to the highest setting, the
simulation performs the aircraft calculations more accurately and more
frequently. Unless you are running the simulation on an older, slower PC, we
