## What the aircraft actually flies over

From Sydney the path crosses Australia, then 1,290 km of open water, then Indonesia, then 1,463 km of open water.

The furthest the great circle gets from the equator is 33.9°S, 0% 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 Sydney the aircraft points north-west (299°); it arrives into Singapore heading north-west (313°). That is 15° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.

One economy seat on it is about 891 kg of CO₂e each way, counting non-CO₂ warming.
