The position of the downwash column needs to be specified in <i>eye-relative</i> coordinates by setting <b>/environment/aircraft-effects/wash-x</b> and <b>/environment/aircraft-effects/wash-y</b>. If these are zero, the air column is assumed to be right underneath the eye point, any non-zero values displace the center northward or eastward from the eye point. To work in external views, the displacement needs to be computed by e.g. a Nasal script or property rules, the same is true if the rotor is not close to the eye point. | |||
The strength of the downwash column <i>on the ground</i> is set by <b>/environment/aircraft-effects/wash-strength</b>. The parameter influences both the radius in which the effect is visible as well as the overall strength (up to a maximum). Aircraft maintainers need to adjust strength based on parameters like altitude AGL, rotor RPM, rotor radius and whatever else might influence the downwash. | |||
