Normally someone on the ground might give you directions as to where you need to go to be exactly at the right spot to pick it up (I guess). In the game this is not the case and the markers on the GPS are not accurate enough.
I think it would be nice to have a visual aid to help you to the exact location for the cargo to be attached. I've posted an example below. The center of the crosshair is the helicopter, the blue dot is the exact location of the cargo, the aid is very precise and sensitive and only activate for example 2 or 3 meters away from the cargo. Or some kind of aid can be added to the instrument left from the example.
