Before reaching the Final Approach Fix (FAF) on an ILS (Instrument Landing System) approach, pilots must confirm their intentions regarding the type of approach they are utilizing. Notifying Air Traffic Control (ATC) of a coupled or auto-land approach is crucial for several reasons, including coordination and maintaining safety in the airspace. For instance, when a pilot is flying on autopilot with an automatic landing system engaged, ATC needs to be aware of this for effective traffic management and to provide any necessary instructions or assistance during the approach.

While it's essential for pilots to ensure they are following procedures outlined in the approach plate and checking weather conditions before the FAF, these activities are typically part of pre-approach preparation rather than an explicit requirement just prior to the FAF. Initiating visual landing procedures would only apply if the approach transitioned from instrument to visual and is not a standard step before reaching the FAF in an ILS approach. Therefore, notifying ATC about the specifics of the approach is the most accurate response concerning actions required before reaching the FAF.
