How would you guide this plane this plane to the airport?
To describe movement we need to know a direction and a magnitude.

5. Airport
N
100 km
Why are instructions like
this not used?
The turn measurement (25°) is relative, it depends on knowing which
direction the aircraft is currently moving.
Instead we use
absolute directions,
according to north.
“Turn 25° to your right and fly for 700 km.”

When we use maps, we use a bearing and a distance to describe movement.

Bearings are always
at least 3 digits.
Why put a 0 in front of the 30°?
