    David,

    You answered a big question of mine, by stating that Daniol is from the 1950s. I'm thinking that H.O. 229 was compiled in the 30s and 40s and used en masse in WW2. This glut of navigators who were running the industry for the next 40 years had enough inertia to preclude the acceptance of anything new. Still to this day, I was unable to interest my Kings Point CelNav instructor from 34 years ago to even look at this. His job as he stated is to train for the Coast Guard license exam. A test that is 80 years out of date. Mariners can be "old dogs" at times.

    Matt
