Applies when the follower is directly behind at the same level or less than 1,000 ft below, crossing behind at the same level or less than 1,000 ft below, or on the same approach. With less than 1,000 ft between them, radar separation also applies: shown here as 3 NM at low level and 5 NM at flight levels. Keep whichever is larger. Wake values from ICAO Doc 4444; check both against MATS RAC before teaching. Sped up 4×. Drag a label to move it.
