EQUIPMENT MODIFICATIONS AND FEASIBILITY DEMONSTRATION FOR IMPROVEMENT OF THE PHASE I UNIVAC ATC DATA PROCESSING SYSTEM
Abstract
The tasks are divided into four major problem areas: (1) real-time clock function, (2) data recovery, (3) data voiding by character and field, and (4) FAA system manual. As work progressed it became apparent that the proposed design on the real-time clock was not feasible. The only practical means found for generating time was to derive a pulse from a one-revolution-per minute motor. A data register is used to provide storage and counting ability to convert the one per-minute pulses into computer code time. The design using the magnetic tape unit for the data recovery system has certain shortcomings such as programming problems and overlap of the data re covered and the data printed during normal oper ation. It is therefore recommended that data recovery be accomplished by extracting data directly from the general storage drums. This would avoid duplicate printout of flight strips and programming problems with the implementation of CUE. Data voiding by character and by field is used to eliminate the time-consuming and error-prone backspacing procedure. The voiding system allows the operator to instruct the T+F Unit to void the previous character or the field that was being filled. The FAA System Manual enables technical personnel to understand the system and to provide continuing personnel with a more thorough understanding of the complete system.
