ABSTRACT
In this chapter, we consider certain aspects of the mechanics of equilibrium flight which involves the modelling of steady uniform flight and steadystate aerodynamic forces. Also considered to a certain extent is the analysis of performance of the aircraft that is relevant to equilibrium flight, and it involves quasi-steady models of flight dynamics and aerodynamics which can also be characterised as the very slowly varying component of the aircraft’s dynamics. A more detailed presentation of performance aspects may be found in books dedicated to aircraft performance analysis such as Perkins and Hage [1], Miele [2], Russell [3], Hull [4], Anderson [5] and Vinh [6].
