What is Aircraft flight mechanics?

Aircraft flight mechanics are relevant to fixed wing and rotary wing aircraft. An aeroplane , is defined in ICAO Document 9110 as, "a power-driven heavier than air aircraft, deriving its lift chiefly from aerodynamic reactions on surface which remain fixed under given conditions of flight".

Note that this definition excludes both dirigibles , and ballistic rockets. Technically, both of these could be said to experience "flight mechanics" in the more general sense of physical forces acting on a body moving through air; but they operate very differently, and are normally outside the scope of this term.
