8.3 Regional destinations are always in capital letters (other than "The"). London is no longer treated as being a regional destination and should be included in the list of place name destinations in lower case letters and in mileage order (London will usually be the furthest place signed and therefore be on the bottom line).
8.4 The aircraft symbol may be used alongside and to the right of an airport name in accordance with the general rules on the positioning of symbols. The symbol should be vertical, with gaps to any line above or below being the same as for a route number patch. Where the airport name is the same as a place name destination on the sign, the aircraft symbol may be used on its own on a separate line only if it is quite clear which airport is being signed. Examples are shown in figure 8-2.
ROUTE CONFIRMATORY SIGNS INDICATING TWO ROUTES
8.5 Where destinations are reached by turning onto another route they can be listed separately, as shown in figure 8-3. This type of sign would be used where the junction is reached before the next destination on the existing route. In the case of a primary route sign which includes local destinations, the sign would be used where the junction is reached before the next primary destination. Where a primary destination on the present route is reached before the junction, a sign with a single route number, as shown in figure 8-1, is more appropriate.
8.6 The second route number may be placed at the top of the sign, as shown in the example "B4040 (A41)" (see figure 8-4). This is appropriate when all destinations on the sign are located on the bracketed route. However, for economy of space, this sign may also be used in the circumstances described in para 8.5, although no indication is given as to which route applies to which destination. In the example, "Potten End" and "Gaddesden" could well be local destinations on the B4040 which then joins the A41 leading to "Aylesbury". Signs of this design are helpful to drivers navigating by route numbers.
8.7 The appropriate spacings for various combinations of tiles and patches are shown in figure 8-4 Other dimensions and design rules are as described in paras {{#8.1|8.1]], [#8.3|8.3]] and 8.4.
