What is, precisely, the function of far field monitor in ILS?
Apr 23, 2024 · Per FAA Order 6750.16, the far field monitors are placed on the final approach course centerline, usually near the inner and/or middle marker beacons. Since this is on the centerline, the expected DDM is 0 (or very close to 0 if the siting is not exact).
d. Localizer Far Field Monitor (FFM). This equipment provides additional monitoring of the localizer signal in the runway approach area. Although lengthy time delays (15 to 120 seconds typical) prevent nuisance alarms, the FFM is a useful indicator of critical area
monitors, dual 75 Mz transmitters for the inner, middle and outer markers, plus remote control and monitor indicator equipment at the airport control tower.
Instrument Landing System (ILS) — Millard Towers Ltd.
Millard’s frangible towers can also be used to support Near-Field Monitors (NFM), and Far-Field Monitors (FFM). Similar to other ILS equipment, these applications have stringent deflection requirements.
Reducing flight inspection intervals has become a major goal in many countries. To achieve this goal accurate ground measurements must be performed regularly and a strong correlation with flight measurements must be established.

3-3-7. FAR FIELD MONITOR (FFM) REMOTE STATUS UNIT
Oct 7, 2018 · Installation of the FFM remote status indicating units is necessary to attain the integrity necessary to meet internationally agreed upon reliability values in support of CAT III operations on Type II ILS equipment.
• Localizer far field monitoring (FFM) equipment, normally required for CAT III ILS • Localizer and glide path near field monitoring (optional) • Remote control status unit (RCSU), Control Tower Unit (CTU) and maintenance SW. Several equipment types are available for an ILS configuration: • Localizer Transmitter
