**Need to Know Stuff**- Qantas uses the Boeing 747-400 aircraft

https://www.qantas.com/us/en/about-us/our-company/fleet/qantas-b747-400.html- The 747-400 maximum fuel capacity is 14,200km for travel

- Distance from Sydney to Johannesburg is 11,060km on the globe

- Flight time is 13h 20m

- Therefore, a plane travels 830km/h

**Distance on the Flat Earth**-Longitude of Sydney Airport is 151.1 degrees East

-Longitude of Johannesburg Airport is 28.2 degrees East

*Difference of 122.9 degrees*-Sydney Airport is 13764km from North Pole

-Johannesburg Airport is 12887km from North pole

**Math**Use Rule of Cosines

d^2 = a^2 + b^2 -2ab cos(C)

d = 189447696 + 166074769 -2(12764)(12887)(-.54)

d= 23,090

**Conclusion**The distance from those two points on the Azimuthal Projection is 2.08x greater than the distance on the globe, therefore a plane will have to travel 2.08x faster, or 1726km/h.

This is impossible because the maximum speed of the aircraft is only 988km/h.Furthermore, the maximum fuel capacity of the aircraft can travel a distance of 14,200km.

That is only 60% of the fuel needed to cross the distance on the Azimuthal Projection.
