During a precision radar or ILS approach, how does the rate of descent required to remain on the glide slope change with increasing ground speed?

During a precision radar or Instrument Landing System (ILS) approach, the rate of descent required to stay on the glide slope is influenced by ground speed. As ground speed increases, the aircraft needs a higher rate of descent in order to maintain alignment with the glide slope, which is typically set at a specific angle, commonly 3 degrees.

When an aircraft is flying faster (higher ground speed), it travels through the same vertical distance in a shorter amount of time. To maintain the glide path, the pilot must increase the descent rate. Therefore, as ground speed increases, so does the required rate of descent. Understanding this relationship is crucial for pilots to ensure they maintain proper approach angles and ultimately achieve a safe landing.

The other considerations related to descent rates and glide slopes focus on factors such as maintaining a specific angle or altitude, or variations due to situational changes, but these do not affect the fundamental relationship between ground speed and required descent rate during a precision approach.
