What Does GLD Stand For?

GLD stands for Glide Slope

GLD, or Glide Slope, refers to a critical component of an Instrument Landing System (ILS) used in aviation. It provides vertical guidance to aircraft during the approach phase of landing, ensuring they maintain the correct descent angle towards the runway. The glide slope transmits a radio signal that pilots and their instruments interpret, allowing for precise altitude control and enhancing safety during final approach, particularly in low visibility conditions.
