Definition
N is the standard abbreviation for north, one of the four cardinal directions used in aviation navigation. North corresponds to a heading or bearing of 360° (also expressed as 0°) on the compass rose and is the reference direction from which all other compass bearings are measured.
Plain English
N is short for north. It points to the direction at the top of a compass and is used as the starting point for measuring all other directions.
Context Anchor
Seen on charts, airport diagrams, weather information, and notices where space is limited.
Derivation
North comes from Old English “norþ,” meaning the north direction. Aviation shortens it to N because charts and notices often need compact direction labels.
Why Pilots Care
Almost everything in navigation is measured from north — headings, bearings, runway numbers, and wind direction. Knowing which north is being referenced (true or magnetic) matters for accurate navigation.
Intuition Check
Do not read N as just a letter or as “up on the page.” In this aviation context, N means north, and the actual north direction depends on the chart or navigation reference being used.
Example Sentence 1
The pilot turned to a heading of 360° to fly due N.
Example Sentence 2
Turn right to a heading of 360 degrees to fly due north.
