What does ELT stand for?

The term ELT stands for Emergency Locator Transmitter. This device is crucial for search and rescue operations as it transmits signals that help locate an aircraft in distress, particularly in the event of a crash or an emergency landing. The primary purpose of an ELT is to alert authorities and facilitate the swift response needed to locate and assist pilots and passengers. When activated, it emits a distress signal that can be received by satellites or ground stations, making it an essential safety feature in aviation.

The other options, while appearing plausible, do not correctly represent the widely accepted terminology or function of the device. The incorrect alternatives misstate the functions of the ELT; for example, "Emergency Landing Tool" implies a device used during landing procedures rather than for locating a downed aircraft. The correct understanding of ELT is vital for pilots, as it directly relates to safety and emergency preparedness.
