‘Just Noticed this was mentioned already. Will just leave here for now.’
I think it would be Very Helpful if the Frequency that other pilots are Currently On, could be displayed, when Hovering over their particular Icon. If not there, then on the sidebar when their icon is selected.
The Main reason for this is when there is No Active ATC and you need to speak with another pilot about runway assignments, spacing, taxi directions, etc…
Many times pilots are either on CTAF (or not aware that a CTAF Frequency is being used), Unicom or still on a Frequency from an Active ATC sector. Showing their Current Frequency can eliminate possible on-ground and in-air confrontations.
