An electric taxi motive control system of a first aircraft comprises a first aircraft position determining system configured to generate a first aircraft position signal, a first aircraft receiver, configured to receive transmissions of a second aircraft position signal, a first aircraft pilot interface configured to accept an input indicative of a first aircraft desired speed, and a first aircraft electronic controller configured to; determine a aircraft separation distance indicative of the distance between the first aircraft and the second aircraft, compare the aircraft separation distance with a safe distance value; and generate a modified first aircraft commanded speed signal when the aircraft separation distance is less than the safe distance value.
