This paper discusses a second generation microprocessor-based prototype system to acquire, analyze, and store selected environmental and physiological data from a pilot during flight. The Aircrew Inflight Physiological Data Acquisition System IFPDAS II consists of an input multiplexer and analog-to-digital converter, a heart rate detector, a microprocessor, and a permanent memory device. The microprocessors operating system monitors eight sensors, extracts desired information, and stores these reduced in permanent memory. After the flight these data are transferred to a land-based computer which completes the data processing and graphs the following environmental and physiological information versus flight time 1 cabin absolute pressure, 2 cabin altitude, 3 Z-Gs, 4 heart rate, 5 breathing rate, 6 minute ventilation volume, 7 inspired oxygen quantity, and 8 expired oxygen quantity. The completed IFPDAS II prototype provides the desired information well within the required accuracy.
