A method for a paired approach procedure in a trail aircraft, the method comprising: receiving instantaneous target aircraft state data from an automatic dependent surveillance-broadcast; receiving instantaneous state data of the trail aircraft from a navigation system; obtaining aircraft-specific parameters for the trail and target aircraft from a database; processing the state data of the trail aircraft and target aircraft state data and aircraft specific parameters for both the target and trail aircraft to determine a target safe speed zone for the trail aircraft to perform a paired approach with a target aircraft, and a recommended speed for the trail aircraft; rendering, on a display system, a paired approach bar comprising: flight identifying text for the target aircraft; a PAB safe trail aircraft speed range extending from above a trail aircraft minimum safe speed to a trail aircraft maximum speed; a current trail aircraft speed; a target safe speed zone, the target safe speed zone having a maximum speed which is less than the trail aircraft maximum speed and a minimum speed which is greater than a trail minimum safe speed; the recommended speed for the trail aircraft; and a wake risk area caused by the target aircraft, the wake risk area being a range of trail aircraft speeds below the safe speed range and above a trail aircraft minimum speed. receiving instantaneous target aircraft state data from an automatic dependent surveillance-broadcast; receiving instantaneous state data of the trail aircraft from a navigation system; obtaining aircraft-specific parameters for the trail and target aircraft from a database; processing the state data of the trail aircraft and target aircraft state data and aircraft specific parameters for both the target and trail aircraft to determine a target safe speed zone for the trail aircraft to perform a paired approach with a target aircraft, and a recommended speed for the trail aircraft; rendering, on a display system, a paired approach bar comprising: flight identifying text for the target aircraft; a PAB safe trail aircraft speed range extending from above a trail aircraft minimum safe speed to a trail aircraft maximum speed; a current trail aircraft speed; a target safe speed zone, the target safe speed zone having a maximum speed which is less than the trail aircraft maximum speed and a minimum speed which is greater than a trail minimum safe speed; the recommended speed for the trail aircraft; and a wake risk area caused by the target aircraft, the wake risk area being a range of trail aircraft speeds below the safe speed range and above a trail aircraft minimum speed. flight identifying text for the target aircraft; a PAB safe trail aircraft speed range extending from above a trail aircraft minimum safe speed to a trail aircraft maximum speed; a current trail aircraft speed; a target safe speed zone, the target safe speed zone having a maximum speed which is less than the trail aircraft maximum speed and a minimum speed which is greater than a trail minimum safe speed; the recommended speed for the trail aircraft; and a wake risk area caused by the target aircraft, the wake risk area being a range of trail aircraft speeds below the safe speed range and above a trail aircraft minimum speed.
