The Earth: DGCA Air Navigation questions
The Earth is an oblate spheroid, slightly flattened at the poles, turning from west to east. Latitude is measured from the equator and longitude from the prime meridian, and their lines together form the graticule.
This short group of 21 questions is mostly definitions, with a few changes of latitude and longitude to work out. Exam sessions have brought up 3 of them.
A great circle's plane passes through the Earth's centre, and its shorter arc is the shortest route between two points. For positions in opposite hemispheres, change of latitude is the sum of the latitudes. Across the 180 degree meridian, add each position's distance from 180 to get change of longitude.
