Abstract:
1. A method of generating a controlled speed for a following aircraft (Ai) taxiing on the ground in a convoy of aircraft (CA), whereby the following successive steps are performed automatically and repetitively: a) the current values of first parameters corresponding to parameters of at least one followed aircraft (Ai- b) at least one longitudinal separation (Di) which must be observed between said followed aircraft (Ai- c) the current values of second parameters which correspond to parameters of said following aircraft (Ai) are measured; and d) using said current values of the first and second parameters and said longitudinal separation (Di), a controlled speed is calculated which represents a longitudinal speed instruction enabling the following aircraft (Ai) to taxi along a trajectory (TR) common to said convoy (CA) while maintaining said longitudinal separation (Di) relative to said followed aircraft, wherein, in the step d), said controlled speed v i is calculated using the following expression: in which: {tilde over (y)} {tilde over (y)} v v c(s c(s {tilde over (ψ)} {tilde over (ψ)} s s {tilde over (ψ)} υ c(s A(z σ {tilde over (y)} k ci: is an appropriate set point; and D
