Hi, There is an aircraft moving at 300KM/h from its destination due north from an airport. It has to fly to the other airport(North) for 90KM. The wind is blowing at 80KM/h from West to east. At what angle must the aircraft fly to make its destination. From my work out I found it to be N15.467W. here is some work out. let O=V wind Let H=V aircraft O/H=sin Sin Thita=O/H =80/300 Thita=Sin^1(80/300) =Sin^-1(0.2667) =15.467 Does this look right?
