## What the aircraft actually flies over

From Sydney the path crosses Australia.

The furthest the great circle gets from the equator is 34.9°S, 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 Sydney the aircraft points west (261°); it arrives into Adelaide heading west (268°). That is 7° 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 173 kg of CO₂e each way, counting non-CO₂ warming.
