Quick reminder: when you are ATC you can pull up anyone’s information and see their flight plan and the frequency they are currently tuned to.
I bring this up because I’m starting to mess around with controlling in playground and didn’t realize this until last night. I was KSAN approach and I kept asking people to tune to my frequency because I thought they were blasting through the controlled airspace not talking to anyone, in actuality they were already tuned to KSAN tower.
Which brings up another point. It definitely gets hectic but if you are controlling tower and someone jumps to your freq too far out while there is approach active take the second to kick them back to approach, it will make your life easier! I think some of the people I was asking to tune to my freq were ignoring me because they were already talking to tower even though they should have been talking to approach.
Hopefully my bone head mistake / oversight can help someone else out.
