Navigation PPLintermediate
Arrange the directional references in the correct sequence when converting a course measured from an aeronautical chart to the final heading displayed on an aircraft's magnetic compass.
Answer
True heading, Magnetic heading, Compass heading
Explanation
The conventional sequence is **true → magnetic → compass**. Apply variation to convert between true and magnetic references, then apply deviation to convert between magnetic and compass references. Apply signs using the convention taught for the chart and compass card. **Key takeaway:** Do not skip or reverse a reference step. **Glossary:** **Variation**: true-to-magnetic angular difference; **deviation**: magnetic-to-compass error.
