There can be either two sticks with one degree of freedom ora single stick with two degrees of freedom:In the two-stick case, the neutral position is when the stick is centered (zero).Pushing the stick forward causes forward acceleration (positive values), andpulling it back causes reverse acceleration (negative values). The righthandand lefthand controls will affect the corresponding side of the vehicle.In the one-stick case, forward/backward acceleration works the same as in thetwo-stick case. However, right or left movement of the stick determines theamount of power applied to the respective track. When the stick is centeredhorizontally, equal amounts of power are applied to both tracks, generating azero output value. Moving the stick to the right will generate positive values,and moving the stick to the left will generate negative values. A Tank TrackControl is a dimensionless analog entity.DV – This control determines the right-to-left positioning of the tank turret. Avalue of zero maintains the current orientation of the turret. A positive valueturns the turret to the right and a negative value turns the turret to the left.DV – This control determines the elevation of the gun barrel in a turret. Avalue of zero maintains the current orientation of the barrel. A positive valueraises the barrel and a negative value lowers the barrel.CA – Allows a device to be generally classified as one that uses the standardcontrols of a submarine.Dive Plane DV – Dive planes control the vertical ascent or descent of the submarineunder power. A zero value indicates level travel. Positive values indicateascent, and negative values indicate descent. A Dive Plane is a dimensionlessanalog entity.Ballast DV – Ballast controls the vertical ascent or descent of the submarine. A zerovalue indicates level travel. Positive values indicate ascent, and negativevalues indicate descent. A Ballast is a dimensionless analog entity.Sailing SimulationDevice5.6 Two-wheeled Simulation DevicesMotorcycleSimulation DeviceBicycle SimulationDeviceCA – Allows a device to be generally classified as one that uses the standardcontrols of a sailboat.CA – Allows a device to be generally classified as one that uses the standardcontrols of a motorcycle.CA – Allows a device to be generally classified as one that uses the standardcontrols of a bicycle.Version 1.1 April 8, 1999
