Understanding ELT Basics

Emergency Locator Transmitters (ELTs) are crucial safety devices in aviation, automatically broadcasting a distress signal to facilitate rapid search and rescue operations following an aircraft incident. These devices, designed to activate manually or automatically upon impact, transmit signals on 121.5 MHz for local receivers and on 406 MHz for satellite detection, the latter providing global coverage and precise location capabilities. The integration of 406 MHz technology marks a significant advancement, ensuring that in moments of distress, the ELT's signal can guide rescuers directly to an aircraft's location, significantly improving the odds of timely and successful rescue efforts.

In our selection, we feature two principal categories of emergency signaling devices:

  • ELT (Emergency Locator Transmitter): Installed directly into the aircraft, ELTs are engineered to automatically activate and transmit a distress signal upon detecting the forces typical of an aviation accident. This automatic activation is crucial for scenarios where manual activation might not be possible, providing an essential safety net. ELTs are a mandatory requirement for a wide range of aircraft, ensuring that no matter where an incident occurs, the chances of locating the aircraft and providing timely assistance are greatly enhanced. 

  • PLB (Personal Locator Beacon): While not installed in the aircraft, PLBs serve a similar purpose to ELTs but with the added advantage of portability. They can be manually activated by an individual in distress, whether in the cockpit or on the ground, making them ideal for pilots, crew members, and even adventure enthusiasts who find themselves in remote locations. PLBs are especially valuable for personal safety, ensuring that individuals have a direct means of signaling for help, regardless of their situation or location. 



Each type of device offers specific benefits tailored to various needs and operations. Choosing the right emergency signaling device—whether a fixed ELT for your aircraft or a portable PLB for personal safety—is crucial for aligning with the operational requirements and safety protocols of your aviation activities. ELTs provide a robust and integrated safety feature, essential for automatic activation during severe impacts, ensuring that help can be summoned even under dire circumstances. In contrast, PLBs offer unmatched versatility and mobility, enabling individuals to initiate a rescue operation from anywhere, be it from a downed aircraft or a remote wilderness area. This distinction highlights the importance of selecting a device that best suits your flight activities and personal risk profile, ensuring you are prepared for any situation that might arise. Both devices play a pivotal role in enhancing the safety net for aviators, forming a dual-layered approach to emergency response that maximizes the chances of a timely and successful recovery.
