The problem: One of the main problems I face with using holds as a controller is the aircraft not following the direction issued (left hand turns, right hand turns) in the instruction.
Request: I think it would be great if arrows signifying left or right hand turns could be added to the holding pattern oval on the map, as an added visual aid for the pilot.
Left hand turns from the VOR shown in the image
Right hand turns from the VOR shown in the image
That way the pilot would know which way to turn when entering the hold if they are unable to determine how to fly the holding pattern properly based solely off the written instructions in the ATC message.
