  • a receiver in the subject aircraft to receive the dynamic conditions data including the position data;

    a display screen in the subject aircraft;

    an on-board computer having means for operating on said dynamic conditions data to generate a graphic display on said display screen from the dynamic condition data updated at subsequent receptions of the dynamic conditions data, including representations of the current positions of the plurality of aircraft derived from said position data, wherein said display is at least initially egocentric with respect to the ATC with the ATC oriented at the focus of said display;

    transformation means in said on-board computer for transforming said dynamic conditions data such that said display is made egocentric with respect to the subject aircraft with the subject aircraft at said focus; and

    means for selectably switching between said dynamic conditions data as received or said dynamic conditions data after transformation by said transformation means in generating said display.
