Hi!
If you're flying an approach and the airport is IMC, you will fly the missed.
If the airport is VMC, you will fly the pattern.
We brief, if a visual, I will remain in the pattern with tower.
I have been sent around twice by the tower in VMC. They told/expected us to fly the traffic pattern.
Regardless, you WILL tell tower you're going around, and then follow instructions.
And, if you're flying a visual to an uncontrolled field, ATC wants you to cancel IFR, and then they will tell U to squawk 1200.
