A go around can either be requested by the air traffic control tower or by the pilot themselves. There are number of different reasons for a go around to be requested, but generally, it is safety-orientated. While they are a safety precaution, go arounds are not only called during an emergency. From the air traffic control tower’s end, there may be another aircraft still on the runway or some sort of debris that has been left behind. On the pilot’s end, go arounds are usually requested as a result of difficult weather conditions or an onboard technical issue. Strong gusts of wind or severely limited visibility can make landing very difficult. In these cases a go around may be the safest option. If an aircraft tries to land without its full technical capabilities, the risk of an accident is greatly increased. A jammed landing gear, for example, throws most chances of a normal landing out of the window.
