At what point does the flight enter the final approach phase of the ILS RWY 25L at LAX?

The correct answer is the intercept of the glide slope, as this phase marks a critical transition in an aircraft's approach to landing. As the aircraft descends along the glide slope, it is following the precise vertical path toward the runway, which is defined by the Instrument Landing System (ILS). This phase typically begins when the aircraft intercepts the glide slope at the designated altitude, which indicates a stable descent towards the runway.

Understanding this concept is essential for pilots and dispatchers, as it ensures proper coordination and communication during the final approach phase. The glide slope typically guides the aircraft down to the runway, allowing for a safe and controlled landing when visibility may be limited.

Regarding the other options, while locations like FUELR INT and HUNDA INT are points in the approach procedure, they do not specifically define the final approach phase. The final approach fix is often a point where the aircraft is established on the localizer, but it is the intercept of the glide slope that signifies the start of the final descent directly aligned with the runway. Thus, selecting the glide slope intercept is vital for understanding the transition into the final approach phase.
