According to this law, at low speed, the aircraft is steered by the nose landing gear wheels. The more the speed increases, the less the nose landing gear is used, in favor of the rudder.
- the distribution of the use of the steering means of the aircraft therefore depends solely on its speed, and therefore does not take into account in particular the meteorological conditions likely to influence the trajectory of the aircraft.
