Abstract : Possibilities and limitations in ionospheric research with an aircraft as carrier are described; the experiments comprise LF and HF pulse sounding, VLF reception, and magnetometer recordings. The mobility of the Flying Laboratory permits observation of the rare and strong events in the ionosphere which are caused by solar eclipses and eruptions as well as topographic anomalies, auroras and artificial nuclear tests. The observations of these phenomena and special measurements of ionospheric drift, of deviative and nondeviative absorption, and of reflection height made the development of special recording and playback methods necessary. Ray paths of the different possible modes arriving at an airplane are derived. (Author)
