What is the relationship between wind and navigation?



The wind triangle describes the relationships among the quantities used in air navigation.


The wind triangle is a vector diagram, with three vectors :-
1. The air vector represents the motion of the aircraft through the air mass. It is described by true airspeed and true heading.


2. The wind vector represents the motion of the air mass over the ground. It is described by wind speed and the inverse of wind direction. Note that by convention wind direction is given as the direction the wind is from. In a vector diagram such as the wind triangle, wind direction must be stated as the direction the wind is blowing to, or 180 degrees different from the convention.


3.The ground vector represents the motion of the aircraft over the ground. It is described by ground track and ground speed. The ground vector is the resultant of algebraically adding the air vector and the wind vector.
