Which signal is transmitted upon ejection with the ELT system?

The correct answer involves the signal transmitted by an Emergency Locator Transmitter (ELT) upon ejection. When the ELT is activated, whether due to impact or manual activation, it emits a distress signal that can be detected by search and rescue operations. This signal is specifically designed to convey information about the location of an emergency situation, thereby aiding in the rapid response by rescue teams.

The ELT typically operates on specific frequencies designated for distress signals, such as 121.5 MHz or 406 MHz, depending on the model and type of ELT. This capability allows the search and rescue units to quickly ascertain the location of the transmitter and provide assistance, making the ELT a critical component in aviation safety.

The other choices relate to components or aspects of search and rescue systems but do not accurately describe the specific function of the ELT system upon ejection. The choice that refers to the signal transmitted from the ELT directly captures what occurs in that emergency situation, emphasizing its role in immediate location signaling.
