Hi,

The problem with this model is that it is not
compatible with other models. For instance, F=ma. If the wind applies a
force to an aircraft in flight, where is the acceleration?

The wind applies a force. That force is cancelled by the horizontal
component of lift. So the net force is zero and the acceleration turns
out to be zero too.

If you like to you can also calculate two accelerations. As the mass
stays the same those would cancel each other in the same way.

Ciao, MM
