Just say you're on final approach on a calm day and are following a larger airplane, you'll want to fly above their profile to fully ensure wake seperation. That's fine but how do you tell if you're above their profile?
Are there any visual references or cues one can use to ensure you are in fact higher then they were at your current distance out?
Does making sure the plane you are following appears 'below' the threshold work?
