Before the
Federal Communications Commission
Washington, D.C. 20554
In the Matter of
Review of Part 87 of the Commission’s Rules
Concerning the Aviation Radio Service
FOURTH REPORT AND ORDER
Adopted: November 7, 2018 Released: November 9, 2018
By the Commission:
I. INTRODUCTION;
1. Emergency Locator Transmitters (ELTs) are radio beacons that are carried on board
aircraft and triggered in the event of a crash or other unplanned downing. The Commission authorizes
these devices to serve as an effective locating aid for survival purposes. For years, the ELTs operated
only at 121.5 MHz, with their transmissions monitored by an international satellite-based system (the
Cospas-Sarsat system) that could determine their location over most of the world’s major air and sea
travel paths. By 2010, however, the Cospas-Sarsat system limited tracking of ELTs to a newer type
operating primarily at 406 MHz, thus eroding the utility of the 121.5 MHz ELTs as an effective locating
aid. By accelerating the transition to 406 MHz ELTs with the rule changes we adopt in this Fourth
Report and Order, we will enhance the ability of search and rescue personnel to locate and bring aid to
the victims of plane crashes
