USCG Exam PracticeDanger bearings and danger circles
33 CFR §83.07 requires that proper use be made of radar equipment if fitted and operational. Which of the following actions does the rule specifically identify as part of proper radar use?
- A. Switching to the shortest range scale to maximize target resolution
- ✓ Long-range scanning to obtain early warning of risk of collision and radar plotting or equivalent systematic observationCorrect
- C. Maintaining the radar in standby mode to preserve magnetron life until a target is sighted visually
- D. Relying on ARPA vectors alone without manual verification of target data
Why B is correct
33 CFR §83.07(b) specifically identifies long-range scanning to obtain early warning of risk of collision and radar plotting or equivalent systematic observation of detected objects as components of proper radar use. The rule also cautions against assumptions based on scanty radar information.
