What is the final approach fix for the DAB RNAV 16 LPV approach straight in?

Question

BlackTom AI · Accepted Answer

To tackle this question, I’ll evaluate what each option represents in the context of an LPV straight-in RNAV (GPS) approach to RWY 16 at DAB.
Option: 1600ft
This option is an altitude value, not a fix or a procedure element. While altitude decisions are important on the final segment, 1600 ft itself is not the designation of the final approach fix (FAF) or the initial point where you begin the final approach path. Therefore, this choice does not correctly identify the final approach fix.
Option: Glide path intercept
This choice refers to the act of intercepting the glide path during the final approach portion. On an LPV approach, the glide path is a vertical guidance path, and pilots typically intercept it as they transition from the final approach segment to the instrument landing portion. If the question is asking for the final approach fix, identifying the act of intercepting the glide path as the final approach fix is consistent with some interpretations where the final approach segment begins at the point where you intercept the glide path. In an LPV, intercepting the glide path is a key milestone, and many charts depict the glide path intercept as the start of the final approach. This makes the option plausible as the correct one.
Option: FEMBA
FEMBA is a named fix along the final approach segment on the plate. It often serves as the final approach fix (FAF) or a step in the final approach sequence. If one were strictly identifying the fixed point where the final approach begins, FEMBA would be a typical candidate. However, the question’s wording seems to emphasize the conceptual milestone of the final approach path rather than naming the physical fix, which could explain why this option might be considered less directly correct depending on chart conventions.
Option: DOGRE
DOGRE is another named fix en route near the final approach area, but it is generally not the definitive final approach fix for the straight-in LPV RWY 16. It may serve as an intermediate fix or transition point, but it does not uniquely establish the starting point of the final approach segment in the common depiction of this approach. Therefore, this option is less likely to be correct for identifying the final approach fix.
In summary, while several interpretations exist, the option that centers on the structural transition of the approach — the moment you begin to follow the vertical glide path on the final segment — is the most aligned with selecting the final approach fix concept in this specific context. The other options either describe altitude rather than a fix, name a fix that may not be the official FAF in this depiction, or refer to an intermediate point rather than the final approach milestone.
