Navigation PPLintermediate
Select ALL statements that correctly describe magnetic variation.
Answer
It depends on geographic location., An isogonal connects points of equal variation., An agonic line has variation of 0°.
Explanation
Variation is not constant worldwide; it varies by location and changes over time. An **isogonal** (isogonic line) connects locations with the same variation. An **agonic line** is the special case where variation is zero. Aircraft-induced compass error is deviation, not variation.\n\n**Key takeaway:** Variation is a geographic magnetic-reference correction.\n\n**Glossary:** **Isogonal**: line of equal variation; **agonic line**: line of zero variation.
