19:58 shouldn't it be 135° and not 315° ??

Sir, Longitudinal separations are defined based on the track difference between the first aircraft and the conflict aircraft. First we have discussed the same track -Same direction or crossing tracks (or a portion thereof) with an angle of less than 45 degrees on each side of the track. In other words less than 45 degrees or more than 315 degrees. Here we are trying to find out the aircraft which are moving in the same direction of our first aircraft and the angle between these aircraft if less than 45 degrees both sides of the first aircraft they are called the same track aircraft. Now, in other words less than 45 degrees is understood by you. You have a question regarding the other track difference which is mentioned more than 315 degrees. Assume your first aircraft is on 090 degrees so add 315 to it, 415. But the compass has 360 degree thus subtract 360 so it will become more than 45 degrees and on the other side less than 45. For better understanding l, You just draw your first aircraft on 360 degree and check less than 45 and more than 315 , the drawing will help you to better understand this. Thank you for watching ☺️.
