Discussion of Airplane in Wind

Navigation directions are usually expressed in terms of compass angles as illustrated. The vector additionnecessary to calculate resultant velocity is carried out by calculating the components of each vector.

There are some practical problems associated with this calculation: you can either convert compass angles to standard angles, or do the calculation in compass angles with the relationships shown. If you calculate the standard angle for the final bearing, it can then be converted to compass angle. A final problem is the arctan problem with calculators and computer languages: you have to check the quadrant to be sure you get the correct angle.
