The measurement of vector electric fields from an aircraft which is struck by lightning can provide information on lightning initiation and triggering processes. Calibration of the aircraft to determine geometric field enhancements and to separate the vector components, although difficult, has been accomplished. Data from 31 strikes in the summer of 1985 are presented in three formats. The raw fields measured at the four field meters are presented both to indicate proper operation and because strikes to the wing tips may be strongly related to the local field at the wing tips. The three cartesian vector components of field and the aircraft voltage with respect to its immediate environment are next shown followed finally by an azimuth-elevation-magnitude presentation which appears useful for triggering studies.
