During what scenario might a pilot decide to initiate a go-around?

A pilot may decide to initiate a go-around primarily when approaching a runway that has traffic ahead. This situation might arise when the pilot realizes that there is insufficient space or the conditions are not safe for landing due to the presence of another aircraft on the runway. Safety is the paramount concern for pilots, and when encountering obstacles or any unforeseen circumstances that could jeopardize a safe landing, a go-around allows them to reposition the aircraft and reassess the landing.

The other scenarios presented do not typically warrant a go-around. For instance, being in a situation where the aircraft is too light may affect landing performance, but it does not immediately necessitate a go-around. Similarly, favorable wind conditions are generally beneficial for landing and would not lead a pilot to decide on a go-around. Lastly, maintaining perfect control of the aircraft indicates that the landing approach is going well, which does not provide a reason for a go-around. Thus, the decision to go around is often driven by safety concerns, best exemplified by the presence of traffic on the runway ahead.
