The Stockholm to Helsinki route drawn as a great circle arc on a globe

What the aircraft actually flies over

From Stockholm the path crosses Sweden, then 232 km of open water, then Finland.

The furthest the great circle gets from the equator is 60.3°N, 100% of the way along.

Holding a single compass bearing the whole way would cover almost exactly the same ground, so on this route the flat map and the globe agree.

Leaving Stockholm the aircraft points east (76°); it arrives into Helsinki heading east (82°). That is 6° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
