, [RADAR-E3-Q1] MV Albatross Beacon bearing 004° - Regarding manual target acquisition for MV Albatross
Beacon at bearing 004° range 6.2 NM, what is correct procedure per ARPA operational standards?
A. Use manual acquisition by placing acquisition cursor over echo and pressing ACQ, wait 1-3 min for full
vector establishment
B. Immediately activate trial maneuver without acquiring target
C. Switch off ARPA and rely on visual bearing only
D. Set vector mode to relative and disable past positions
Correct: A | Focus: manual target acquisition | Vessel: MV Albatross Beacon | Bearing 004°
Rationale: For manual target acquisition concerning MV Albatross Beacon, manual acquisition requires precise cursor placement
on radar echo, followed by 3 minute tracking for valid CPA/TCPA. ARPA needs stabilized heading and speed input. For bearing
004, maintaining acquisition guard zones ensures automatic detection if manual fails. IMO requires tracking within 1 min and
full vector in 3 min. Disabling vectors violates safety. Per STCW and IMO Model Course 1.07, ARPA functions for manual
[RADAR-E3-Q2] MV Barents Venture bearing 008° - For MV Barents Venture bearing 008° showing unstable
tracking, how should ARPA automatic target acquisition be managed?
A. Increase trial maneuver speed to 30 knots to force solution
B. Cancel tracking and re-acquire manually, check sea clutter and target size, verify gyro stabilization
C. Ignore loss and proceed without ARPA
D. Switch to true vectors and delete past positions
Correct: B | Focus: automatic target acquisition | Vessel: MV Barents Venture | Bearing 008°
Rationale: Unstable tracking of MV Barents Venture at 008° in automatic target acquisition indicates weak echo or maneuvering
target. Best practice cancels then re-acquires, adjusts clutter controls, and ensures ARPA has steady own-ship data. Trial
maneuver is predictive only and cannot fix tracking. True/relative vector selection does not stabilize track. Proper
automatic target acquisition handling improves CPA accuracy per IMO A.823. Per STCW and IMO Model Course 1.07, ARPA
[RADAR-E3-Q3] MV Calypso Horizon bearing 012° - When performing ARPA tracking initiation for MV Calypso
Horizon at 012° with CPA 0.7 NM, what does ARPA trial maneuver display?
A. Actual alteration of own ship course immediately
B. Deletion of all tracked targets
C. Predicted new CPA/TCPA based on own ship proposed course/speed change without altering actual target tracks
D. Automatic transmission of maneuver via AIS
Correct: C | Focus: ARPA tracking initiation | Vessel: MV Calypso Horizon | Bearing 012°
Rationale: Trial maneuver for MV Calypso Horizon is a simulation function. When evaluating CPA 0.7 NM at bearing 012°, ARPA
extrapolates new CPA/TCPA if own ship were to maneuver now, leaving real tracking unchanged. It shows predicted vector
changes for all tracked targets. This allows COLREG compliant decision before executing turn. ARPA tracking initiation never
controls helm or AIS, it is purely predictive for safety assessment. Per STCW and IMO Model Course 1.07, ARPA functions for
