A simple, correct pedagogical presentation of airplane lateral-directional dynamics

Various shortcomings and inaccuracies in the existing approach and presentation of airplane flight dynamics in pedagogy have been identified. An improved pedagogical presentation is offered which is simple - uses the different timescales in lateral-directional dynamics to cleanly derive roll, dutch roll, and spiral mode parameters, more acceptable - starts with the lateral-directional dynamics equations rather than the complete six degree of freedom formulation, and correct - uses a physically correct model of the dynamic (rate) derivatives and employs the concept of a static residual. The redundant and confusing concepts of dimensional derivatives and static stability are junked following a companion paper using a similar approach to the longitudinal dynamics.
