The active/away state of a pilot is a crucial feature for ATC to see if you are at your device to recieve commands. The active and away state is determined by if you are touching your screen. If you haven’t touched your screen for 2 minutes it will show you as away on ATC’s end and even on your end as a pilot. If you tap on an aircraft on the map as a pilot you can see if they are active.
We can see on the flight strips, ATC Menu and in your information if you are active or not. We can also see how long you have been away for.
If you are away you may receive commands but we know not to expect you to respond to these commands because you’re not at your device. The only exception to this is if you are at any other state of flight other then cruise. If you’re climbing, descending, landing, etc. you will need to be at your device.
