This paper describes a system for receiving, processing, and displaying real time telemetry data from vehicles during test flights. The system has unique characteristics which provide it with greater flexibility and more processing power than previous systems in this category. The heart of the system is a 32 bit 'Super-Mini' computer that provides laboratory-level processing power in a flight test environment. Inputs to the Super-Mini include a hardware pre-processor and a high-speed array processor. The hardware pre-processor is used to perform engineering-unit conversions, check limits, collect maximum and minimum values for selected measurements, and further pre-process and sort data for computer entry. The highspeed array processor runs Fast-Fourier transforms on selected data arrays, thereby relieving the computer of this necessary but time-consuming aspect of flight data analysis. The display subsystem is user oriented. It utilizes high resolution graphics to give flight test personnel the opportunity to obtain meaningful, easily-interpreted test results and to get an immediate indication of any alarm conditions.
