What happens when the Emergency Locator Transmitter (ELT) is activated?

The Emergency Locator Transmitter (ELT) is a crucial safety device used in aviation to aid in search and rescue operations. When the ELT is activated, it transmits a distress signal that includes vital location information. This signal is picked up by search and rescue forces, including satellites and ground stations, which can then determine the position of the aircraft in distress. This immediate transmission significantly increases the likelihood that rescuers can locate and assist those on board.

The other options describe functions that are not associated with the ELT. It does not produce loud noises meant for alerting people nearby, does not serve as a landing signal for aircraft, and it certainly does not deploy a parachute. The primary purpose of the ELT is to facilitate the prompt location and rescue of downed aircraft, making its location transmission function critical in emergency situations.
