A method comprising: at a processor located on an ownship, receiving position and heading of another aircraft; receiving position, heading, and flight path information of the ownship; determining flight path information of the other aircraft based on at least a portion of the received information; determining if a wake condition exists from the other aircraft based on at least a portion of the received information and at least one predefined threshold; and generating a wake icon if the wake condition is determined to exist, wherein: the wake condition is determined to exist when either (i) ownship altitude is below a first threshold altitude and above a second threshold altitude, wherein the first and second threshold altitudes are based on the other aircraft's altitude, or (ii) the other aircraft's flight path intersects the flight path of the ownship when viewed from a plan view; and the wake icon comprises a plurality of segments, one of the segments presented in a first color, intensity, pattern, or flash rate, and each of the other segments presented in different colors, intensities, patterns, or flash rates than the first, and each segment represents a distance, a distance associated with a predetermined time value or a dynamically determined time value based on relative speed of the ownship and other aircraft, wind speed, wind direction, and altitude. at a processor located on an ownship, receiving position and heading of another aircraft; receiving position, heading, and flight path information of the ownship; determining flight path information of the other aircraft based on at least a portion of the received information; determining if a wake condition exists from the other aircraft based on at least a portion of the received information and at least one predefined threshold; and generating a wake icon if the wake condition is determined to exist, receiving position and heading of another aircraft; receiving position, heading, and flight path information of the ownship; determining flight path information of the other aircraft based on at least a portion of the received information; determining if a wake condition exists from the other aircraft based on at least a portion of the received information and at least one predefined threshold; and generating a wake icon if the wake condition is determined to exist, wherein: the wake condition is determined to exist when either (i) ownship altitude is below a first threshold altitude and above a second threshold altitude, wherein the first and second threshold altitudes are based on the other aircraft's altitude, or (ii) the other aircraft's flight path intersects the flight path of the ownship when viewed from a plan view; and the wake icon comprises a plurality of segments, one of the segments presented in a first color, intensity, pattern, or flash rate, and each of the other segments presented in different colors, intensities, patterns, or flash rates than the first, and each segment represents a distance, a distance associated with a predetermined time value or a dynamically determined time value based on relative speed of the ownship and other aircraft, wind speed, wind direction, and altitude. the wake condition is determined to exist when either (i) ownship altitude is below a first threshold altitude and above a second threshold altitude, wherein the first and second threshold altitudes are based on the other aircraft's altitude, or (ii) the other aircraft's flight path intersects the flight path of the ownship when viewed from a plan view; and the wake icon comprises a plurality of segments, one of the segments presented in a first color, intensity, pattern, or flash rate, and each of the other segments presented in different colors, intensities, patterns, or flash rates than the first, and each segment represents a distance, a distance associated with a predetermined time value or a dynamically determined time value based on relative speed of the ownship and other aircraft, wind speed, wind direction, and altitude.
