Spanwise lift distribution

a) The starting vortex is generally created as a continuous increase of vorticity over a long distance,
unless the aircraft suddenly changes angle of attack to create lift. After that, as angle of attack, flap
settings etc. are changed, corresponding starting-vorticity distributions are left behind.
b) These vortices don’t last forever: viscosity and disturbances in the air dissipate them, or they run into
the ground (the runway) and get dissipated.
