Abstract

All private aircraft are equipped with a device which is called the emergency locator transmitter (ELT). Many private aircraft presently in use have no means of notifying the pilot if the ELT has been activated. The authors describe a solution to the problems using 2-μm CMOS technology. Because FAA regulations prohibit the device from being powered by or attached to the aircraft, this design is completely portable and powered by a 9-V battery. The design was realized using a 2-μm, double-metal, single-poly, p-well CMOS process. The chip will detect aircraft ELT transmissions at a frequency of 121.5 MHz. In addition, the monitor will appropriately enable or disable output to an external flight recorder. Theoretical and experimental results for the first-pass aircraft communication monitor design are encouraging
