What is the function of the G hot key?

• A. Mute guard for a minute
• B. Engage guard mode permanently
• C. Toggle the landing lights
• D. Initiate crossfeed

Answer: (A)

The G hot key is meant to temporarily mute the guard channel for about one minute. Guard is the continuously monitored communications channel, so muting it briefly lets you talk or operate on the main channel without guard chatter getting in the way. After roughly a minute, the guard monitor automatically resumes. This is why it’s the best fit: it provides a short, controllable pause rather than a permanent change. The other options don’t fit because they describe unrelated actions (permanently enabling guard, toggling landing lights, initiating crossfeed) that aren’t about silencing guard for a short period.
