Flying an EC chance? TCAS is standard in most 139s, but 135 & 145 transponder signals don’t seem to be reliably depicted on screen. If transponding, the 139 should see you several miles away otherwise.
After lifting the helicopter departing appears to transition forward and collide with the other helicopter in the climb. Are the app/dep pads longitudinally offset?
