It is basic flying skill, but some accidents demonstrated that they sometimes caused a problem. The most iconic one, in my opinion, is the Emirates go around without power.
Not forgetting the Flydubai Flight FDB 981 B737-800 on 19 June 2016. It was a straightforward go-around on instruments yet the pilot blindly tried to follow the HUD beyond its tolerances and dived into the ground. A terrible accident. There is no exemplary skill needed for a go-around in a 737. Properly trained, it is a basic manoeuvre after all. All the usual excuses can be made (fatigue etc) but it boils down to staggering incompetence in instrument flying ability.
