+(vertebrate) flight, implementing the aerodynamic power model.  Flight
+performance is estimated based on basic morphological measurements such as body
+mass, wingspan and wing area.  @code{Afpt} can be used to make predictions on
+how animals should adjust their flight behaviour and wingbeat kinematics to
+varying flight conditions.")
