What could happen if an ELT is not operational during an emergency?

If an Emergency Locator Transmitter (ELT) is not operational during an emergency, the most significant consequence is that search and rescue operations may be delayed. An ELT is designed to emit a signal that helps rescuers locate an aircraft in distress. When an aircraft goes down or makes an emergency landing, the ELT should activate automatically to transmit its location to search and rescue teams. Without a functioning ELT, these teams will have to rely on other means of locating the aircraft, which can take substantially longer and may reduce the likelihood of a successful rescue, especially if the accident occurs in a remote area.

The other options do not accurately reflect the functions or capabilities associated with an ELT. An ELT does not automatically turn on during a crisis if it is not operational. Pilots do not gain easier navigation through an inoperative ELT, as it does not relate to navigational aids. Lastly, an aircraft will not be tracked continuously without a functional ELT because it is the ELT's purpose to provide a signal for tracking during an emergency situation.
