Which statement about the search sector is false?

Which statement about the search sector is false?

• A. It is defined by azimuth and elevation
• B. It uses 310° azimuth
• C. It uses 72° elevation
• D. It uses frequency to define the sector

Answer: (D)

The search sector is defined by angular limits in two dimensions: azimuth and elevation. It describes the portion of space the sensor is scanning, determined by where you’re looking horizontally (azimuth) and vertically (elevation). Frequency, on the other hand, relates to which channel or wavelength is used and does not set the spatial boundaries of the sector. That’s why stating that the sector is defined by frequency is not correct. The other statements fit the idea that the sector is described by an azimuth value and an elevation value (the numbers given could specify the sector’s direction or extent for a particular scenario).
