I must have slept through the FAA exams that referenced a "Map."
Map= Obtained at AAA or DMA, (and used for Land Navigation).
Chart= Used for Aeronautical or Nautical Navigation, (and each use different projections).
My first FI would of slapped me if I ever asked him for a map.
I do admit I couldn't solve that equation without using artificial assistance.
