Wind velocity vector and desired ground track direction.
Wind velocity vector and desired ground track direction.
An airplane travels with a constant airspeed \(v_a\) relative to the air. A steady wind blows due east at a constant speed \(v_w\) relative to the ground, where \(v_w < v_a\). The pilot aims the airplane such that its resultant motion relative to the ground is directed due north.

Which of the following correctly pairs the heading of the airplane with its resulting speed relative to the ground?
