It is simple reflection of preparation in the other four areas. This actually happened to me one night, while flying with my instructor, when an airfield manager changed runways, and turned the ILS off on my runway. Establish a positive rate of climb. Keep the wings level and continue to climb straight ahead. With a sure-fire plan that is in your bag of tricks, everything will work out.
Forethought makes it happen on command.
It is a simple principle essential to flying. Application of power during a missed approach or go around is a good case in point. If you can't effectively handle a sudden burst of maximum power on the instruments at night, then don't jam the throttles through the firewall. Easy does it. The idea of applying maximum power is to do it steadily and uniformly.
