In honor of the Cleared to vs.Cleared Direct thread. I wanted to ask a question that has been bugging me as of late: What is the difference between a "Go Around" and a "missed approach?" Can only the tower call a "go around" and a pilot only call going "missed approach?" Is it possible to only go "missed" in IFR low visiblity conditions,or can you (as a pilot) go "missed" on a severe clear day or is that simply go around? Confused...cause I am let me know guys/gals?
