==Decision altitude and height== Once established on an approach, the pilot follows the ILS approach path indicated by the localizer and descends along the glide path to the decision height. This is the height at which the pilot must have adequate visual reference to the landing environment (e.g. approach or runway lighting) to decide whether to continue the descent to a landing; otherwise, the pilot must execute a [[missed approach]] procedure, then try the same approach again, try a different approach, or divert to another airport. Usually, the decision on whether or not the pilot continues with the approach relies on whether the runway is visible or not, or if the runway is clear or not.
