Heliports are identified by a white capital letter "H" centred within the takeoff and landing area. Where it is necessary to enhance the visibility of the letter "H", it may be centred within a dashed triangle. Hospital heliports are identified by a red capital letter "H" centred within a white cross. The letter "H" will be oriented with magnetic north, except in the area of compass unreliability where it will be true north.
