MCIC Land Navigation Practice Test 2026 - Free Land Navigation Practice Questions and Study Guide

In land navigation you work with three north references: true north, grid north, and magnetic north. True north points toward the geographic North Pole and stays fixed with the Earth’s axis, giving you a stable reference for long-distance direction. Grid north is tied to the map’s grid lines, so bearings read straight off the map and align with the map itself. Magnetic north is what a compass points to, but it shifts with location and over time due to the Earth’s magnetic field. Being able to use all three lets you read from the map (grid north), relate directions to the terrain (true north), and take compass readings on the ground (magnetic north). In practice you translate between them using grid convergence and magnetic declination, so you can accurately transfer bearings between the map and compass. That’s why this trio is the correct set.
