An advisor system includes a computer-readable storage medium having encoded thereon a program of instructions. Execution of the instructions causes a processor to determine a current state of a first aircraft operating on a movement area of an airport including determining a path vector for the first aircraft. The path vector includes a speed and direction of travel of the first aircraft and identification of a runway intersection the first aircraft is projected to enter. The processor processes a surveillance signal transmitted from a second aircraft operating on the movement area, including determining a quality of the surveillance signal. The processor further determines a movement vector of the second aircraft, and compares the path vector and the movement vector to identify possible interference. Finally, the processor provides an advisory at the first aircraft based on the compared path vector and the movement vector.
