Jeff Van West is one of my favorite modern-day aviation writers. His article, Seeing Double in the November issue is a fine example of Jeff taking us by the hand through important, but oft overlooked and esoteric aspects of our IFR life. But his use of the word declination instead of the correct word, variation, is a fingernail on the blackboard kind of irritant, if you remember blackboards. I have these old yellowed books that I studied in the 50s: AF Manual 51-40, Air Navigation Vol 1, by the Department of the Air Force (1959), page viii, and The American Flight Navigator by John Dohm (1958) page 324.
