CSAR mode permits classification of maritime targets at low sea states out to 30 NM. It functions in an area from 30 to 150 degrees left or right of aircraft centerline. What angular range is this describing?

• A. 30 to 150 degrees
• B. 0 to 30 degrees
• C. 150 to 210 degrees
• D. 210 to 360 degrees

Answer: (A)

The angular range is described as the sector starting 30 degrees off the aircraft’s forward centerline and extending out to 150 degrees on either side. So the coverage is 30 to 150 degrees relative to the centerline, which is exactly the option stating 30 to 150 degrees. The other ranges refer to regions closer to the nose (0–30), around the rear (150–210), or the broader back/side area (210–360), none of which match the described 30–150-degree offset on both sides.
