Question: What is the primary function of an Outer Marker (OM) beacon during an ILS approach?
Answer options:
- To indicate the Final Approach Fix (FAF) and provide a continuous tone.
- To indicate the Middle Marker (MM) and provide a fast-paced tone.
- To indicate the Missed Approach Point (MAP) and provide a slow-paced tone. ✅ To provide a fixed point approximately 4 to 7 NM from the runway threshold, usually co-located with the FAF, and transmit a slow-paced tone (dashes).
Correct answer: To provide a fixed point approximately 4 to 7 NM from the runway threshold, usually co-located with the FAF, and transmit a slow-paced tone (dashes).
Explanation: The Outer Marker primarily indicates the Final Approach Fix (FAF) on an ILS approach, typically located 4 to 7 NM from the threshold, and is identified by a slow Morse code tone (dashes) and a blue light.
