Flight data logging method and voice flight detarekoda

摘要

PURPOSE: To lengthen recording time by recording flight data of the next path except the recorded part of the previous path so as to prevent overlapping in the case where the recorded amount of flight data is less than 50% to the unit recorded amount, and recording plural paths in one track. ;CONSTITUTION: In a device which writes a voice signal from an area microphone and a data signal from an airframe in a tape recorder 4 through a recorder control circuit 3, writing is controlled so as to arrange the flight data in an endless magnetic tape 9 without any gap through the control circuit 13. A writing position in each track is controlled by a signal from a track counter 14. At this time, the numbers of paths for the track number where new writing is carried out, and the track number where writing is carried out for each track are measured to generated odd/even numbers according to the numbers of the writing paths. In the case of an odd number, flight data is recorded in the former half part of the unit recording length, and in the case of an even number, the data is recorded in the latter half part respectively.;COPYRIGHT: (C)1994,JPO&Japio
