Q

You should plot a dead reckoning position after every __________.

🔍 Key Concepts

• Dead reckoning (DR): advancing a position by course, speed, and time • When navigational conditions change (course, speed, or a new fix) • Why frequent DRs are critical for safe navigation and situational awareness

💭 Think About

• Ask yourself: when do you get new information or make changes that affect where your vessel will be? • Which of these choices represents all situations when your predicted track and position should be updated? • If you only updated your DR on one of these events, what important changes in your actual position might you miss?

✅ Before You Answer

• Verify which events change either course, speed, or your last known position (fix) • Check standard piloting practice: DR is usually advanced from every new fix and whenever track assumptions change • Make sure the choice you pick covers all necessary times you must update a DR, not just one type of change
