The map was scaled for a 7310-mile flight from Hong Kong to Las Angeles.
All other distances are measured as indicated and are wrong.
In addition, the flight paths are wrong. On MEL-SCL, the aircraft departs Melbourne and flies Southeasterly over the ocean. The flight path does not fly over Texas. Upon arrival, the Boeing 787-9 approaches Santiago from the Southwest.
The farther south the flight path, the more error is introduced.
