It's very easy Richard.

Click repeatedly on <NEXT WPT on the DISPLAY ADVANCE window on your FMS to advance step by step in your flight plan. You will scroll along the flight plan on your MFD.

Adjust the range with the TILT/RANGE knob as appropriate.

 

That's all you need.

 

EDIT

Once you get to the end of your flight plan, you can also step back to your previous waypoints by clicking <PREV WPT.

Basically every click on <NEXT WPT will bring you one waypoint next, every click on <PREV WPT will bring you one waypoint back.

 

Let me know if this is clear enough, I can post a screenshot if you want.

It's very easy Richard.

 

Super Guys that worked much appreciated - can you guys save a panel state in this bird I can - thanks for the help

The PFD should not even have PLAN display mode as a choice. It's not possible to select that on the PFD. As well, if the MFD is in PLAN mode, the PFD can not be in PPOS mode.

 

And the PFD will NEVER display rivers and/or geopolitical boundaries!!!
