 (b) a manoeuvre restriction intended to maintain existing separation.
TAWS means terrain awareness and avoidance system.
TAWS-Class B+ means a TAWS that:
 (a) is a TAWS-Class B; and
 (b) includes a colour terrain display that meets the following requirements:
 (i) the displayed terrain information must be depicted relative to the aeroplane's position such that the pilot can estimate the relative bearing to the terrain of interest;
 (ii) the displayed terrain information must be depicted relative to the aeroplane's position such that the pilot may estimate the distance to the terrain of interest;
 (iii) the displayed terrain information depicted must be oriented to either the heading or the track of the aeroplane, and may include an additional selectable north-up orientation format;
 (iv) variations in terrain elevation must be depicted relative to the aeroplane's current or projected elevation (above and below) and be visually distinct, except that terrain that is more than 2 000 feet below the aeroplane's elevation may be excluded;
