Thanks Gary & Ken & David !
That's exactly what I was looking for ! The HO 249 explanation make sence to me because I want to do my flow of CelNav. exercises [ongoing from the 17th century till now] in a Traditional way at my desk with pencil/paper/charts and the many Pub.'s, no electronics involved, except for the checkup's.
