What must be applied to pull the orange flags out of view in the ILS indicator?

• A. Aircraft power only
• B. Valid ILS signals only
• C. Both aircraft power and valid ILS signals
• D. No signals are needed

Answer: (C)

The correct response regarding the orange flags on the Instrument Landing System (ILS) indicator involves understanding how the system operates to provide accurate navigation information. The orange flags signify that the ILS is either not functioning properly or that the aircraft is not receiving valid ILS signals. To pull the flags out of view, both aircraft power and valid ILS signals must be present. When the aircraft is powered, the ILS equipment can receive and process signals. However, even with power, if the ILS does not receive valid signals from the ground-based ILS transmitter, the flags will remain visible, indicating that the system is not providing usable data. Thus, valid ILS signals are required to ensure that the system is actively providing approach guidance. The combination of both power and valid signals is essential for the ILS indicator to operate correctly and for the flags to be suppressed, indicating the system is ready for use during an approach phase. In essence, both elements are critical for ensuring that the aircraft can safely rely on the ILS for landing assistance in various weather conditions.
