Abstract : A CV-580 aircraft was instrumented with external displacement current density sensors, surface current density sensors, current shunts, and static electric field mill sensors and was flown in the neighborhood of active thunderstorms in central Florida during Summer 1984. Electromagnetic data were collected for 21 direct lighting strikes to the aircraft at altitudes between 2,000 and 18,000 ft. The data consisted of DC to 2 MHz analog records and 10.24 microsecond windows of digital samples taken at five nanosecond intervals. The data show the physical mechanism of lightning attachment to the aircraft. Keywords: Airborne lightning test; Aircraft lightning; Direct lightning strike; Lightning waveforms.
