Elementary Mr. Watson: Navigating RF—A Glide Path Approach to Design Success

April 24, 2025 | John Watson, Elementary, Mr. Watson

On a flight, I can always tell when we begin our descent because that subtle drop in my stomach tells me the altitude has changed. Landing an airplane involves a gradual, precise process called the glide path. It descends at the correct speed and 3-degree angle to touch down smoothly and safely on the runway without bouncing or coming to a sudden stop. Pilots use specialized tools like the Instrument Landing System (ILS) or GPS to stay on the correct path. Lights on the ground, called PAPI lights, help pilots know if they are too high or too low.
