Abstract : A portable measuring device has been developed for assessment of cockpit/cabin environmental parameters during flight. The apparatus can be employed in a medium-sized aluminum suitcase as a single self-contained unit, or subunits and sensors can be deployed about the aircraft cockpit/cabin as conditions permit. For confined cockpits, a seatpack is used to contain subunits. The sensors include a hot-wire anemometer (sensitive from 0 to 400 ft/min), a dew point hygrometer (of range -40 to +50 C), an ambient temperature probe (0 to 100 C), and an absolute pressure transducer (0 to 800 mmHg). The output from each is linearized by internal circuitry and processed for both immediate digital display and simultaneous storage, together with time-code and voice record, on magnetic tape. The system's small size and flexible configuration permit derivation of mission-specific environmental profiles for aircraft ranging in size from single-place fighters to larger transport aircraft. Results obtained are useful in both the establishment of life support equipment design criteria and assessment of the physiological stresses of flight. (Author)
