How long can ELT types A/B and C transmit at -20 degrees Celsius?

1. Minimum 12 hours

2. Minimum 36 hours

3. Minimum 48 hours

4. Minimum 72 hours

The correct answer is: Minimum 48 hours

The correct information regarding the transmission duration of Emergency Locator Transmitters (ELTs) types A/B and C at -20 degrees Celsius is that they are designed to transmit for a minimum of 48 hours. This specification is crucial for ensuring that in the event of an emergency, the signal can be sustained long enough for search and rescue operations to locate the transmitter. ELTs are mandatory safety devices on aircraft that activate upon a crash or significant impact, emitting a distress signal to assist rescuers. The capacity to function for an extended period at low temperatures is a vital characteristic because search operations may take time, especially in remote or challenging environments. The specification of a minimum of 48 hours emphasizes reliability and enhances the chances of detection, thus improving survival rates. Other options suggest different durations, but the minimum duration defined by regulations and industry standards for types A/B and C specifically stipulates 48 hours of transmission at low temperatures, making it the correct choice in this context.
