Definition
Meaning
The study or technique of sailing or navigating along a constant compass bearing (rhumb line).
The branch of navigation dealing with courses of constant bearing, which appear as straight lines on a Mercator projection but as spirals converging on the poles on a globe.

Examples
By CEFR Level
- Before modern computers, sailors had to understand loxodromics to plan long voyages.
- The professor's lecture on loxodromics elucidated why a constant compass course does not yield the shortest path on a spherical Earth.

Learning
Memory Aids
Mnemonic
LOXodromics keeps you on a LOXed (locked) compass bearing, spiraling towards the pole.
Conceptual Metaphor
A PATH IS A SPIRAL (on a globe), A PATH IS A STRAIGHT LINE (on a map).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'локсодромия' (loxodromiya) – this is the correct Russian equivalent. The English term is 'loxodromics', not a direct calque like 'loxodromy'.
Common Mistakes
- Using 'loxodromics' as a synonym for any navigation. Mispronouncing as /lɒkˈsɒdrəmɪks/. Using it as a verb (e.g., 'to loxodromic').

Frequently Asked Questions
While the underlying principles are understood, modern electronic navigation (GPS) and great-circle routing have made practical loxodromic calculation largely obsolete, though it remains a key historical and conceptual topic.
Loxodromics deals with constant bearing courses (rhumb lines). Orthodromics deals with great-circle courses, which represent the shortest distance between two points on a sphere.
The primary adjective is 'loxodromic' (e.g., a loxodromic spiral). 'Loxodromics' itself is a noun denoting the field of study or technique.
Historians of science and navigation, specialist cartographers, certain mathematicians, and possibly naval/maritime history enthusiasts. It is not a term for general use.
