""The user may select to present own ship as a true scaled outline oriented in the direction of heading relative to CCRP and drawn using a thick solid line style with the same basic colour used for own ship symbols.,Automatic selection of the true scaled outline is permitted (see 5.1.1).,The true scaled outline shall not be used when heading is unknown in a gyro/THD-stabilised mode, or when the beam of the outline is less than 3 mm.,NOTE A loss of heading will force the radar into head-up mode (see IEC 62388); in this case, the true scaled outline is still permitted.""
