25-60-00 EMERGENCY EQUIPMENT Back
A. General
The emergency equipment helps the flight crew, the cabin attendant and the passengers if there is an emergency.
B. System Components
The ELT is powered by an internal battery and can be readily removed from the aircraft. When activated, the ELT transmits on three frequencies (121.5 MHz, 243.0 MHz and 406.025 MHz). The two basic emergency frequencies (121.5 MHz and 243.0 MHz) are mainly used for homing in the final stage of rescue operations. A signal is transmitted on these frequencies for approximately 100 hours. The 406.025 MHz frequency is sued by the COSPAS-SARSAT satellite system to locate and identify the aircraft. The signal transmitted on this frequency is automatically stopped after 24 hours to comply with COSPAS-SARSAT requirement.
D. Function of Underwater Locator Beacon (ULB)
The ULBs help persons to find the Cockpit Voice Recorder (CVR) or the Flight Data Recorder (FDR) if the aircraft goes into water
