The qualities of hot wire anemometry measuring techniques for laboratory experiments, mock-ups, and flight tests are examined in the framework of the development of the Do-328 regional airliner. Probes for velocity measurements were calibrated in a small wind tunnel. The wind tunnel was designed to produce very low flow velocities. The method is shown to be particularly useful in the following cases: multichannel flowmeters for measuring the trim of air flux in tube systems; ventilation comfort indicators in an aircraft cabin; and test instruments for the flow configuration in free flow and boundary layers.
