Bob... You've been hanging around with too many Brown Shoes :-)

The aviators use the DD MM.mmm, all right, but the Black Shoe NOAA/USCG/DMA 
marine charts are still the old DD MM SS.sss. I agree with you that it's 
obsolete, and what's more a  pain in the neck, since you have to mentally 
convert their Notice to Mariners chart corrections before you can plot 
them. Does the Navy still have sailors doing chart corrections with 
electric erasers and india ink, or is it automated now?

DD MM.mmm does make more sense.
