This report describes a field application of the Computer Automated Page Layout (PLA) system to the development of a procedure training aid for the SH-3D/H Helicopter, as part of the Training Analysis and Evaluation Group's (TAEG) ongoing development effort to provide tools for the design and publication of technical training aids in a format which relies heavily on graphics for use in teaching procedures. It describes the steps required to use PLA in the design and production of the "Procedure Training Aid for the SH-3D/H Systems Checklist," which contains numerous photographs and line drawings. Also included is a summary of opinions of students and instructors concerning the training aid's usefulness. On the basis of this demonstration, it is concluded that the PLA computer aided authoring routines can be used in developing procedure training aids, and that aids developed using PLA can support the learning of complex procedures and will be accepted by both students and instructors. It is recommended that PLA be used to develop training materials when the procedures must be performed from memory or a simple checklist; are difficult to learn; and/or are for operation of the equipment. A six-item reference list includes several related reports available from NTIS (National Technical Information Service). Appendices provide a biographical description of the author and 34 pages of the 65-page procedure training aid prepared for this project by Richard C. Ewell using the PLA system. PLA operates on the WANG 2200 MVP minicomputer. (LMM)
