Could you please advise how the MSA  incorporated in the PLOG is arrived at. Can the parameters be changed. The Horizontal and Vertical Warnings dont seem to have any effect and I cant seem to find any reference in the documentation.

I was taught +500 ft above highest terrain/object 5nm either side of track. Then add further 300 ft for possible unmarked obstacle on top of terrain. 

So thats +800ft for terrain, +500ft for obstacle
