The initial compass bearing from Colombo to Singapore is 102° (ESE), so a great-circle flight path leaves Colombo heading roughly ESE. 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 5.58° and the longitude difference is 23.96°. 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.
