The invention discloses a flight dynamic monitoring method supporting aircraft four dimensional space-time information. The method comprises: the message issued by the plane is received, the message element in the message is extracted, the message element comprises the longitude, latitude, flight altitude and flight time of the plane; according to the preset projection mode and the longitude and the latitude, the latitude and longitude point of the plane is projected onto a preloaded map to draw the trail of the latitude and longitude; according to the flight altitude, latitude and longitude,the flight profile trail are drawn. With the invention adopted, the supporting for four dimensional monitoring of longitude, latitude, altitude and time can be realized.
