air2ground

Computes groundspeed from airspeed and wind.

Allows estimation and modelling of flight costs in animal (vertebrate) flight,
implementing the aerodynamic power model described in Klein Heerenbrink et al.
(2015) <doi:10.1098/rspa.2014.0952>. Taking inspiration from the program
'Flight', developed by Colin Pennycuick (Pennycuick (2008) "Modelling the flying
bird". Amsterdam: Elsevier. ISBN 0-19-857721-4), flight performance is estimated
based on basic morphological measurements such as body mass, wingspan and wing
area. 'afpt' can be used to make predictions on how animals should adjust their
flight behaviour and wingbeat kinematics to varying flight conditions.
