Dear Zvi Doron, not having seen the illustration in "Air Navigation" by Weems I can only suspect that the Fav? Diagram is the "ingeniously contrived graphical method for solving spherical triangles" (Cotter) first published by Fav? and Rollet de l`Lisle in 1892. It is described in Cotter`s "History of Nautical Astronomy" (p. 338) and in Chap. XXI ("Comparison of Various Methods of Sight Reduction") of the 1977 edition (Vol. 1) of the "American Practical Navigator" (p. 601-602). It is also referred to in the "Lehrbuch der Navigation", Vol. II (Berlin 1906), p. 171, which points out that it has been reissued by H. Maurer in "Annalen der Hydrographie..." in 1905. According to Bencker "Regimen of the Sea or Nautical Compendium" the diagram was published under the title "Abaque pour la d?termination du point ? la mer" in the "Annales hydrographiques" in 1892 and in the "Revue Maritime" in January 1893.
