SYSTEM AND METHOD TO MONITOR TRAFFIC AND PROVIDE ALERT IN FIM-PA POST PLANNED TERMINATION POINT

Abstract:

A method in a trail aircraft for monitoring the separation distance between the trail aircraft and a lead aircraft during a flight deck interval management paired approach (FIM-PA) procedure is provided. The method includes: receiving an assigned spacing goal (ASG); receiving traffic information regarding the lead aircraft that indicates the position, heading and ground velocity of the lead aircraft; retrieving a predetermined tolerance limit and traffic information regarding the trail aircraft that indicates the position, heading and ground velocity of the trail aircraft; setting a range limit that is at least as great as the absolute limit indicated by the ASG plus the tolerance limit; monitoring the range and ground speed differential between the lead aircraft and the trail aircraft; and generating a caution alert indicator when a monitored condition detected from monitoring the range and ground speed differential indicates a potential problem.
