Describes the instrument landing systems which allows a pilot to safely land an airplane in bad weather conditions. The basic system consists of four (or five) transmitting stations. The localizer transmits a signal down the runway to provide lateral guidance and line the aircraft up on the runway. The glide slope transmits a signal which is inclined with respect to the ground at an angle of about 3 . It ensures that the aircraft will make a smooth descent to the end of the runway while safely clearing all obstacles on the ground under the approach path. The other transmitters are the fan markers.
