(Refer to FAA-CT-8080-3F, Figure 227.) Refer to the APA (Centennial) ILS RWY 35R procedure. The PFAF (Precision Final Approach Fix) intercept altitude is

Explanation

In the profile view of the APA ILS RWY 35R chart (Figure 227), the lightning-bolt symbol marking glideslope intercept points to the underlined altitude 8000, just outside the LOM (CASSE, I-APA 8.1 DME). On a precision approach the final approach fix is the point where the glideslope is intercepted at that altitude, so the PFAF intercept altitude is 8,000 feet MSL. The 7977 shown at the LOM is the glideslope altitude when crossing the marker, and 7080 is the localizer-only minimum altitude after LECET.
