Final Approach Fix
What is final approach fix?
The final approach fix (FAF) is the point from which the instrument (IFR) final approach to an airport begins, marking the start of the final approach segment. On the chart, it's shown by a Maltese cross for non-precision approaches and by the lightning-bolt symbol (glideslope/glidepath intercept) for precision approaches. Crossing it at the correct altitude is critical to a safe approach. Think of it as the "now you're committed to descend and land" gate on the approach.
Also known as: FAF, final approach fix
