5.56 Symbols associated with route arms which are not horizontal should be positioned adjacent to any associated legend in a manner which produces the best sign layout. In most cases the symbol will be placed to the right of the legend. The "P" parking symbol and the aircraft symbol should be positioned as described in para 5.55.
5.57 Some symbols may be centred below the legend tiles. This is the case with the ferry symbol illustrated in diagrams 2007 and 2120. The lorry symbol when used on a black panel is always centred horizontally on any legend above. The panel will be ranged left with any other blocks associated with the same route symbol.
5.58 Those symbols which have a directional element to their design are listed at Appendix B and should face either left or right to accord with the general direction of the associated route arm. Where the route arm is vertical the symbol should face left. The aircraft symbol is normally rotated to point in the same direction as the route arm, except that the symbol should never point below the horizontal.
5.59 An example of the use of symbols on a map type sign is illustrated in figure 5-34.
