The concensus among the majority of operators that I was in touch with was that there was no way of avoiding occasions where the PIC abandoned the controls. In many cases the drop-off and recovery locations for geologists, seismic crews etc. were so remote and so numerous there was simply no alternative but to supervise the ground activities once the aircraft had landed
.
I'm confused as to how a location can be safe enough to leave the ac rotors running but not safe enough to close down
