DEFIs Training Mission [05] - Observing the In-Ground-Effect (IGE) in the KA50 Black Shark 3

This is a mission to test if the socalled In-Ground-Effect (IGE) is actually noticeable.

At altitudes of less then one rotor length the In-Ground-Effect (IGE) should provide some extra lift.
You can try and feel if this is the case by reducing the collective to account for the IGE.
This is barely noticeable at least to myself. Maybe this is not even modelled correctly in DCS?
Any experienced helicopter pilots can maybe comment on this.
In theory with the coaxial rotors of the KA50 this IGE should be more pronounced than with other helicopters.
Unfortunately there are no charts available for the KA50.
