Prepar3D McCoy Helicopter Landing Effect v2.5, tested in Prepar3D V2.5. This package replaces two effects and adds a new helicopter wake.
The two effects are rotor wash for dirt and water. The water effect has been modified for better visibility against three dimensional waves.
Four levels of intensity are included, small, medium, large and maximum.
In the video and all screen shots the Bell JetRanger III demonstrates medium, the Sikorsky UH-60 uses large and the Sikorsky Air-Crane is set to maximum.
All rotor effects can be used in any combination.
