Sight Reduction Tables For Air Navigation Pub. No. 249 (HO-249) Commercial Edition

Because of the high price and spotty availabliity of the Government editions,we have reprinted these as Commercial Editions from official Government electronic files. They are economical, and sized at 90% of the originals. They have soft instead of hard covers and their smaller size of 8.5 x 11 inches is easier to carry and store. SW 2.1 lbs
