 The scale of the map is that chosen by means of the range selector (the range value selected corresponding to the diameter of the outer circle). No navigation station characteristics (in the ND bottom corners) and associated bearing pointers are available in this mode. The A/C position on the map is represented by a track-orientated yellow A/C model (item b)

 B. Heading or Track Presentation
 (1) Actual heading The A/C actual magnetic heading is readable around a graduated rotating scale (only for a 90. sector ahead of the A/C in ARC mode), with respect to a fixed yellow reference line at the top of the scale.
