FAA Ground School Practice Test

The primary purpose of an emergency locator transmitter (ELT) is to assist in locating an aircraft in the event of an accident. When an aircraft is involved in a crash or experiences a significant incident, the ELT is activated, either automatically by the forces of the crash or manually by the crew. Once activated, the ELT transmits a distress signal on specific emergency frequencies, which can be received by search and rescue teams and satellites. This vital function significantly enhances the chances of locating the wreckage and survivors in a timely manner, thereby saving lives and facilitating recovery efforts.

Other functions related to navigation assistance, communication with air traffic control, and monitoring weather conditions are not associated with the ELT, which makes it clear that its design and operation focus specifically on search and rescue efforts following an accident.
