In HOT mode, which statement is true?

In HOT mode, both microphones are active, which allows for better communication and situational awareness. This mode is designed to ensure that pilots can use both the oxygen mask microphone and the standard helmet-mounted microphone simultaneously, providing flexibility and redundancy in communication. This dual microphone setup is particularly useful in environments where background noise may be high or where clear communication is crucial for safety and coordination.

The functionality of both microphones being active in HOT mode ensures that pilots can clearly transmit and receive information, whether they are using the oxygen mask or the helmet-mounted setup. This feature enhances operational effectiveness, ensuring that the crew can maintain communication under various conditions.
