What is the minimum altitude descent procedure when cleared for the S-ILS 9 approach from Seal Beach VORTAC?

The minimum altitude descent procedure when cleared for the S-ILS 9 approach from Seal Beach VORTAC requires the aircraft to follow specific altitude restrictions in a clearly defined sequence. In this case, the correct procedure is to descend and maintain 3,000 feet to the JASER Intersection (INT), after which the pilot should intercept the Glide Slope (GS) down to the decision altitude (DA) of 960 feet.

This procedure is designed to ensure that the aircraft is safely positioned on the correct approach path and altitude before engaging the Glide Slope, which assists in descent to the runway with precision. The step of maintaining 3,000 feet until reaching JASER INT ensures that the aircraft is at a safe altitude above the terrain and any potential obstructions in the area.

Following this altitude until JASER INT also allows for proper alignment and configuration of the aircraft for the subsequent Glide Slope approach, which is crucial for a safe landing, particularly in instrument conditions. The indication to descend to 960 feet aligns with the standard procedure to ensure that the aircraft is at the correct altitude before reaching the decision point for landing.

The other options present various altitude settings and descent profiles that do not align with the established procedures for this specific
