The resultant vector is the GROUND VECTOR that represents True Course or Track and

Ground Speed. The result is the Wind Triangle (Figure 4.5-7).

The direction of the ground vector is the aircraft's intended or actual path over the ground,

and the magnitude is the aircraft's groundspeed. The tail of the ground vector is our origin,

and the head is the aircraft's current or predicted ground position. On the Wind Triangle,

the angle formed by the Air and Ground vectors is called crab angle. (Figure 4.5-7)
