AbstractData from the Space Shuttle is recorded on magnetic tape during manufacture, during pre-flight tests and during flight. Thus a permanent record is obtained for all tests. When a tape recorder suddenly stops before the end of its run, some data will not be recorded. Tape recorders run silently and make no sound when they stop. A tape recorder that is not running is easily observed, but constant visual monitoring is impractical. Yet it is important that personnel become aware of the problem at once. An audio alarm that sounds when a tape recorder stops before the end of its run will alert personnel. An alarm in use at Rockwell’s Flight Systems Laboratories not only sounds when a tape recorder stops before it is supposed to, but it turns on a standby recorder in less than two seconds.
