I had a helicopter student once who had this problem.
It was potentially very dangerous because of the requirement to manoeuvre a big helicopter in small confined areas and to get the crewman to clear the tail of the aircraft. There was a case of a Wessex crew who got it wrong and the pilot went left instead of right or vice versa. The aircraft hit a mast by a helipad and rolled down the hill, killing at least one of the pax and very seriously injuring one of the pilots.
Similar to the UAS QFI who drew on the stude's flying gloves, (actually I think I did that once, too) I made 2 inch high letters "L" and "R" in sticky orange dayglo and put them on the back of his green leather gloves. It worked. He's still around! I think the stigma of having the gloves made him concentrate more and it cured him.
Now. Why do my wife's knickers say "C and A" in them?
