Detailed Description

A library of functions to aid the computation of the kinematics of an aircraft. This library is currently under development and is far from complete. The majority of the functions handle constant velocity turns and movement with constant ground speed acceleration.

Unless otherwise noted, all kinematics function parameters are in internal units – angles are in radians, linear speeds are in m/s, distances are in meters, time is in seconds.
