Which item is explicitly listed as part of Sensor Data for AMOS?

• A. Provide listing of AMOS back-up equipment
• B. Location of AMOS sensors in relation to runways
• C. Date AMOS sensors installed
• D. Legacy Fixed-Base Sensors

Answer: (A)

Sensor Data in AMOS covers the hardware and support items needed to keep the sensor network running, including what back-up equipment exists. Providing a listing of AMOS back-up equipment is explicitly included because it supports maintenance, rapid replacement, and continuity of observations if a primary sensor or component fails. This kind of inventory helps ensure readiness and reliability of the measurement system.

The other items don’t fit as part of Sensor Data: where the sensors are located relative to runways belongs to siting or installation details, not the backup and maintenance inventory; the installation date is historical asset information rather than current sensor support data; and mentioning legacy fixed-base sensors refers to older equipment as a category, not to the current sensor-support data itself.
