Overline Altitude Lable

[Bentorio]

I would like to know is there anyway to overline an altitude label like in the example.

I'm using ArcGIS and ArcGIS for Aviation 10.3.

By the way my featuer is a shapefile not a geodatabase.

Hello,

   There does not appear to be any text formatting tags, to handle this situation.    I think you would need to use a font with the Overline already included.  ArcGIS for Aviation includes some PLTS Outline fonts, but none that have the outline only on the top.  Maybe you can find or create a font for this.
