Because the Earth is curved, the actual heading shifts gradually along the route — pilots and navigation systems update it continuously instead of holding a single fixed compass bearing.
The latitude difference is 8.56° and the longitude difference is 13.67°. Each degree of latitude represents about 111 km, which is one reason cross-latitude routes feel longer even when the map looks similar to east–west journeys.
