an aircrafts black box consists of the flight data recorder and cockpit voice recorder. it is equipped with a Underwater Locator Beacon which If a plane crashes into the water, this beacon sends out an ultrasonic pulse that cannot be heard by human ears but is readily detectable by sonar and acoustical locating equipment. The beacon sends out pulses at 37.5 kilohertz (kHz) and can transmit sound as deep as 14,000 feet (4,267 m). Once the beacon begins “pinging,” it pings once per second for 30 days (requirement today is 90 days). This beacon is powered by a battery that has a shelf life of six years. no where have i found information of the black box being equipped with some form of tracking device if it ends up on land instead of water. can you find a black box on land without physically locating an aircraft?
