Overview Navigation Flight Planning Hazard Avoidance Additional Features Hazard Avoidance MOTION VECTORS There are two pilot-selectable and mutually exclusive types of motion vectors, Absolute and TargetTrend, which are differentiated by color and function. Absolute vectors are white and indicate ground track as reported by the traffic. TargetTrend vectors are green and indicate the flight path and position, relative to the aircraft, at which the traffic will be after the passing of one of four predetermined time intervals. The end of the TargetTrend vector indicates the traffic's predicted location relative to the predicted location at the end of the look-ahead time. For example, if traffic is ahead of the aircraft and traveling along the same track but at a slower rate. The motion vector would point opposite of its indicated direction of flight showing that the aircraft is overtaking the traffic. Traffic Display Range Traffic's Predicted Relative Location in 5 minutes TargetTrend TargetTrend Look-ahead Time The TargetTrend look-ahead time interval is automatically adjusted from 30 seconds to five minutes and corresponds to the traffic display range setting. The greater the range setting, the longer the time interval and vise versa. Refer to the table below for more details.
