member Dave Gardiner |Flight Planning and Navigation| An
aircraft in flight is airborne and subject to the movement of
the air mass in relation to the surface; i.e. the wind. The
relatively low cruising speed of light aircraft makes them
particularly affected by wind velocity. Consequently the
calculation of the wind effect on aircraft movement relative to
the ground is a major part of light aircraft flight planning and
navigation.basic forces module of the flight theory section we
said it is common practice to estimate resultant forces non-
mathematically by drawing scaled, arrowed lines to represent
each vector quantity; this produces the resultant of two vector
quantities in a vector triangle or parallelogram. The lengths of
the lines represent the magnitude of ea
