Instrument Flight Manual, US Navy NATOPS 1967

This is an original 1960's-era Instrument Flight Manual for the Naval Air Training and Operating Procedures Standardization Program (aka NATOPS...of course!) dated 1967.  At about 170 pages, it details the use of flight instruments of the era, such as indicators for Altitude, Radio Magnetic compass, Bearing Distance Heading, Horizontal Situation, and Attitude, for basic instrument flight procedures and IFR, with additional background and other aspects.  It is a useful guide for instruments used in Viet Nam War-era aircraft such as the F4 Phantom II as well as for helicopters such as the UH-1 Huey, and many others. 

Despite slight discoloring of the cover, it is in exceptional condition for its age. A few pages have a pencil marking crossing out the section and some yellow highlights, but all is clearly legible.  A fine document.
