The decision to employ direct rather than diffraction recording in the Lincoln Training System (LTS) is reported. This resulted from the findings that direct recording was practical at higher densities than previously thought possible and that rapid access to a number of fiche would compensate for the limited number of frames per fiche realized with direct recording. The initial stages of the educational development program for the LTS, consisting of programs in Principles of Electronics and Air Traffic Control developed at Keesler Air Force Base (AFB) are described. Finally, a report of LTS-3, a microfiche-based training system which will be field-tested at Keesler AFB, is offered. Information is given which explains how a microfiche reader provides access to audio/graphic frames and how lesson branching logic is stored photographically. Supporting author facilities for merging voice and lesson-branching logic and for recording these signals on film are described. In addition, detailed technical data are provided on terminal design, the audio recording system, the audio read system, the LTS-3 terminal/computer interface, the author's voice/data merge facility, and on diffraction-pattern recording techniques.
