What is the intercept altitude for the Precision Final Approach Fix (PFAF) in the APA ILS RWY 35R procedure?

The intercept altitude for the Precision Final Approach Fix (PFAF) is determined based on the specific ILS approach procedure for the runway in question. In the case of the APA ILS RWY 35R procedure, the approach typically provides guidelines that detail the altitude at which an aircraft should be established on the glide slope.

When analyzing the published approach charts, the PFAF intercept altitude is commonly aligned with obstacles and airspace restrictions, ensuring safe vertical separation for aircraft at different phases of their approach. An altitude of 8,000 feet MSL serves as a proper altitude to ensure that the aircraft can safely transition onto the glide path for a precision approach to runway 35R, considering both the required obstacle clearance and operational safety margins.

This altitude ensures that the aircraft is at a sufficient height to intercept the localized glide slope, allowing it to descend correctly to land on the runway while avoiding any obstacles in the vicinity. The specific altitude is established by the procedure designers to facilitate a standard safe approach for all aircraft following that route.
