What is the location of the final approach fix for the ILS RWY 24R?

The final approach fix for an Instrument Landing System (ILS) approach, such as for Runway 24R, is located at the glide slope intercept. This is significant because the glide slope provides vertical guidance to the pilot as they descend toward the runway, allowing for a controlled descent during the final stages of the approach. The glide slope intercept is where the aircraft begins to align with the glide path and is a crucial point for the transition from the intermediate approach phase to the final approach.

In this case, the other options do not accurately represent the position of the final approach fix. The runway threshold is the beginning of the runway where the landing occurs, while the missed approach point is a specific point where a pilot would initiate a missed approach if the landing cannot be made. Additionally, the initial approach fix marks the beginning of the approach procedure and is located much earlier than the point at which the glide slope is intercepted, which is critical for ensuring that aircraft are on the correct descent path as they approach the runway.
