Mute Key Setup (Voice Control)
'Mute' is used to prevent the virtual First Officer/ PNF from acting on any unintentional voice inputs received by the Speech Recognition system.
'Mute' is useful when communicating with on-line ATC, or if you do not anticipate communicating with the virtual First Officer for extended periods of time.
There are two kinds of Mute: Soft Mute and Hard Mute.
