Instrument Flying Training Manuals, Set of 4, USAAF WWII

This is an original set of four instrument flying training manuals published by the US Army Air Force in the early 1940's. Included are:

• Basic Theory and Practice (TO 30-100A-1, Jun 1943, 82 pages)
• Ground Trainer Instruction Guide (using the Link Trainer) (TO 30-100C-1, Aug 1943, 103 pages)
• Advanced with Radio Aids (TO 30-100B-1, Jan 1944, 75 pages)
• Technique in Weather (TO 30-100D-1, Jun 1943, 70 pages)

They are in very good condition given their age. These came to us from the estate of a B-17 flight instructor.
