3. **Examples**:
- For instance, a flight from Perth, Australia (Southern Hemisphere), to Santiago, Chile (Southern Hemisphere), largely stays within the Southern Hemisphere without crossing the equator.
- However, flying from Sydney, Australia, to Buenos Aires, Argentina, might take a route that skirts near the equator but does not necessarily cross it if using a great circle route.

So this example still goes across the equator then?
Apologies for the confusion. Let's clarify:
- Flight from **Perth, Australia, to Santiago, Chile**: This route would generally fly over the Southern Hemisphere, avoiding crossing the equator if the flight path follows a direct great-circle route.
- Flight from **Sydney, Australia, to Buenos Aires, Argentina**: This route would likely involve flying more or less along the equator, which might mean crossing near or over the equator. However, with modern navigation, pilots might choose routes that minimize crossing the equator, but it's not guaranteed to stay entirely in the Southern Hemisphere.
Could you specify if there's a particular route or example you're interested in so I can provide the most accurate information?
