历尽千辛万苦终于找到了
Breitling Emergency 43mm Chronograph with Distress Transmitter
The Emergency is an instrument watch with built-in microtransmitter broadcasting on the 121.5 MHz aircraft emergency frequency. Following a crash or a forced landing, the Emergency will broadcast a signal on which rescuers can home in. The Emergency's transmitter is activated by unscrewing a protective cap and pulling the antenna out fully, it will then broadcast for 48 hours. The transmitter's signal has a range of about 100 miles. This seems like a great idea but I wonder if any pilots actually use this watch.
有个发报装置 能广播48小时 在平地上信号覆盖范围达到100英里 |
