A method for a paired approach (PA) 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 (PAB) 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 (PAB) 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 . <EOS>
