What does the term “Glide Slope” refer to?

The term "Glide Slope" specifically refers to the proper descent path for landing, particularly in the context of an Instrument Landing System (ILS) approach. The glide slope is a key component of the ILS, providing pilots with vertical guidance during their descent toward the runway.

The glide slope works in conjunction with the localizer, which provides horizontal guidance, allowing pilots to precisely approach the runway at the correct angle and vertical profile. Typically, the glide slope is set at a three-degree angle below the horizontal, which is standard for most airport approaches. This ensures that the aircraft descends at a safe and manageable rate, allowing for a smooth landing.

Understanding the glide slope is essential for pilots, especially when flying under instrument conditions, as it helps maintain the correct approach and landing trajectory, promoting safety and accuracy during landing procedures.
