Hi guys ive got an air nav test tommorow and its likely this question will pop up but im not 100% sure what the answer is, according to a PPL Nav book i have it says a Rhumb line crosses longitude meridians at the same angle,where as on web pages it says it crosses all meridians at the same angle, a great circle path is the shortest distance between two points however they are different depending on what chart you use conical or mercator,any help much appreciated !
A Rhumb line track can be described as:
(a) A track that crosses all lines of latitude at the same angle
(b) A track that crosses all lines of longitude at the same angle
(c) The shortest distance between two points
(d) A great circle path
