Q

Heeling error is defined as the change of deviation for a heel of __________.

🔍 Key Concepts

• Heeling error is related to how the magnetic compass deviation changes when the ship heels (rolls), not when it just changes heading. • The formal definition usually specifies a particular amount of heel and whether it depends on heading. • Consider whether heeling error is tied to a specific course or is a property of the compass on any heading.

💭 Think About

• Ask yourself: is the heel of the vessel measured in degrees of heel (roll) or degrees of heading? Look carefully at what each choice is actually describing. • Which option correctly focuses on a change in deviation per unit of heel without confusing that with a particular course or with being the same on all headings? • Does the standard definition of heeling error require a specific compass heading, or is it defined more generally in terms of heel alone?

✅ Before You Answer

• Make sure the definition involves a change in deviation for a small, standard amount of heel (think about whether it is 1° or 2°). • Check whether mentioning a specific compass heading (000°, 180°, intercardinal) is really part of the standard definition, or just extra, misleading detail. • Verify that the option you choose reflects per degree of heel, not per degree of heading or something that must be constant on all headings.
