Instrument Flight, Part 1 Basic Air Work, US Navy 1944 RCAF with the pointer rotating onceThis original WWII era instructional book, Instrument Flight Part One, Basic Air Work, was published by the US Navy in 1944. This manual came to AeroAntique from the estate of a pilot of an SBD Dauntless Dive Bomber, although not marked with its former owner's name. The 155 page book measures ~4. 5 inches by ~7 inches, and is in good condition given its age.
