From: "daveweilacher@earthlink.net"> Does anyone know when H.O. 249 tables were introduced? Hi Dave, all I could find quickly is, according to Bowditch (page 8, section 111) > In 1936 the first volume of Pub. No. 214 was made available; later, Pub. No. 249 was provided for air navigators. > Pub. No. 229, Sight Reduction Tables for Marine Navigation, has replaced Pub. No. 214. I would guess all three HO 249 volumes were published at the same time. -- these are the good old days Cliff Sojourner cls@employees.org
