Thanks for the replies guys, I assumed the PROG page extended a line to the extended centreline with an excecuted INTCPT CRS from PPOS and maybe assumed a rate one turn at current speed onto that magenta line....My gripe is that on approach my people are leaving all sorts of old waypoints lying aroung and don't bother X-checking DTG at anytime. Without an alive GS I get blank looks when I suggest they're a bit low etc...
The absence of a Boeing FCTM in English make it harder to make my point.
