Random Map Question, about coordinates used on Downloaded Hi-Res Syria Map

[Aronis]

Just curious as I could not find with 'the google.'   The downloaded map is quite detailed and uses the same coordinate system as the maps in the briefings for the Campaign, but not the same as the F10 Map. I could not find a good explanation for the coordinate system used.   

Each grid segment has a number in the middle with an exponent.  Such as 4^1, across from West to East grid numbers, for example, read 8^5,7^2,4^9,4^1,3^1,3^0 etc.  I cannot quite see the pattern.  And there are series of Grids with the same number 3^1..

Each of the grid lines has a marking for N or E for Long and Lat(fairly easy to understand), it's just the larger number in the middle of each Box that I cannot figure out.

Just curious, not a Sim issue.

That's the MGRS coordinates, an alternative way of doing coordinates.  The Viper can use them, but I tend to stock to the lat/long the Viper defaults to.

I understand the MGRS, but this map has another number in the middle of each grid which is different. See the image below. The Grid major numbers are not a number and a letter but there are MGRS references on the corners such as CV/CU DV/DU which are MGRS, and it has numbers for Lat and Long on the major lines, it's the big number in the  middle I cannot quite figure out.

Minimal safe altitude for the square

Slightly incorrect. It is actually the Maximum Elevation Figure, and dose not ensure the legally required minimum clearance above terrain/obstacles.

 

 

Some companies, such as Jeppesen, add the required additional terrain clearances (1000ft for terr/obs below 5000ft, & 2000ft for terr/obs above) to the MEF figure to obtain their published MORA (Minimum Off Route Altitude) figures.

I was thinking that based on the mountains but the blocks near the ocean did not seem to match that, but clearly that is the answer.  Thank you very much.
