When controlling you need awareness, you need to know what the needs of the other controllers are.
Does Tower need more arrivals on the right side versus the left side of the airport? Same applies for departures.
How long is the queue to takeoff?
Does Departure need more spacing on the departure leg?
Do you need to stagger departures more to give Departure room?
Is a gate hold in effect?
Does a gate hold need to go in effect?
Is the queue to arrive way to big?
Is the runway exiting effecting ground flow?
Each frequency needs to be aware of what’s going on in the airspace, regardless if it’s their responsibility. You need to work as a team and anticipate conflicts. It’s a domino effect, each frequency needs to be working together to achieve the most efficient flow to get traffic in and out of the airport.
