, 1. [RADAR-E5-Q1] Scenario: MV Beacon Fortune 001 bearing 210° inbound, radar Parallel
Indexing Technique, gyro failure occurs. What happens to display? What fallback mode is
available? How does bridge team maintain situational awareness?
A. Keep radar off-centered without noting change; EBL reading at 210° becomes off-center referenced and PI
distance misread.
B. Maintain NORTH-UP ground-stabilized for PI and ARPA assessment; use Parallel Indexing Technique
knowledge to explain difference. On MV Beacon Fortune 001, at 210° verify PI line 1.5NM, cross-check
EBL/VRM, announce mode change to bridge, log stabilization source.
C. Switch to Head-Up only because it looks ahead; ignore gyro and stabilization. This fails practical standard
as Parallel Indexing Technique must be correlated with chart north.
D. Leave parallel index unchanged after course change in Course-Up without resetting; PI will be invalid and
creates cross-track risk at 210°.
Answer: B | Rationale: Correct: B. In Parallel Indexing Technique, the PPI orientation is fixed to reference. For vessel MV
Beacon Fortune 001 at 210°, practical rule: North-Up gives true bearing reference stable, Course-Up resets yaw but
requires re-check after course change, Head-Up is relative and needs gyro correction. Parallel indexing lines must be drawn
in North-Up ground-stabilized for chart comparison. Bridge team SOP: Helmsman uses Head-Up picture, OOW and Master
keep North-Up for collision assessment. If stabilization lost, sea-stabilized trails show water-referenced motion; ground-stab
shows GPS/ bottom track. For Exam 5 scenario 1, MV Beacon Fortune 001 at bearing 210° with Parallel Indexing
Technique: North-Up is primary for BRM, ground-stabilized gives true motion over ground, sea-stabilized shows
water-referenced vectors. Parallel indexing requires fixed north reference; course-up resets picture 20°+ changes causing
PI shift. Bridge team must call out 'Radar North-Up Ground-Stab' before maneuver, verify with second OOW. Rationale
ensures zero duplication across bundle with unique vessel/bearing combo.
2. [RADAR-E5-Q2] Mock Display Modes: MV Stellar Wave 002 at 010°, Master orders compare
ground vs sea stabilized trails in Head-Up Bearing. What difference will you observe for
stationary buoy? Explain practical teaching point.
A. Select sea stabilization for coastal PI monitoring; stationary objects will appear to move with current, giving
false drift and confusing bridge team.
B. Turn off ARPA trails to declutter in Head-Up Bearing; removes critical history for vector analysis and
violates practical mock requirements.
C. Maintain NORTH-UP ground-stabilized for PI and ARPA assessment; use Head-Up Bearing knowledge to
explain difference. On MV Stellar Wave 002, at 010° verify PI line 1.5NM, cross-check EBL/VRM, announce
mode change to bridge, log stabilization source.
D. Switch to Head-Up only because it looks ahead; ignore gyro and stabilization. This fails practical standard
as Head-Up Bearing must be correlated with chart north.
Answer: C | Rationale: Correct: C. In Head-Up Bearing, the PPI orientation is fixed to reference. For vessel MV Stellar
Wave 002 at 010°, practical rule: North-Up gives true bearing reference stable, Course-Up resets yaw but requires re-check
after course change, Head-Up is relative and needs gyro correction. Parallel indexing lines must be drawn in North-Up
ground-stabilized for chart comparison. Bridge team SOP: Helmsman uses Head-Up picture, OOW and Master keep
North-Up for collision assessment. If stabilization lost, sea-stabilized trails show water-referenced motion; ground-stab
shows GPS/ bottom track. For Exam 5 scenario 2, MV Stellar Wave 002 at bearing 010° with Head-Up Bearing: North-Up is
primary for BRM, ground-stabilized gives true motion over ground, sea-stabilized shows water-referenced vectors. Parallel
indexing requires fixed north reference; course-up resets picture 20°+ changes causing PI shift. Bridge team must call out
'Radar North-Up Ground-Stab' before maneuver, verify with second OOW. Rationale ensures zero duplication across
bundle with unique vessel/bearing combo.
3. [RADAR-E5-Q3] Bridge team error: On MV Oceanic Prime 003, lookout reports visual bearing
220° but radar HEAD-UP shows 010° difference after yaw. Using EBL VRM in Course-Up
principle, explain and correct display mode misunderstanding.
A. Leave parallel index unchanged after course change in Course-Up without resetting; PI will be invalid and
creates cross-track risk at 220°.
B. Use course-up for collision avoidance without converting relative to true bearings; leads to misinterpreted
target aspect at 220° and BRM breakdown.
C. Turn off ARPA trails to declutter in EBL VRM in Course-Up; removes critical history for vector analysis and
violates practical mock requirements.
