"Excess data" on the long range view suggests there may be too many to either display or for the memory (if there is any) and it just blanks that half and gives the message.

Bingo. The display begins processing units right-to-left and halts when the memory is full.. the answer to your question is on the left side of the display in your picture in bold yellow: "EXCESS DATA"

Any idea why it's set to do that? It would seem more logical to have it process from bottom-to-top, so that the nearest airports are shown before the furthest ones.

That's a good question for RW Collins.. most of my experience with these processors is on Airbus Thales equipment.
