I would like very much if you can take me out a doubt:
If I'm remembering well in the SDM, spotting an opposite conflict implies three checkings:
1 - The two airplanes must fly in opposite directions and their strips must not be removed yet. For example, a first airplane flies from A to B and a second airplane flies from B to A.
2 - In respect to the time distances, the time (between the 1st airplane in point A and the 2nd airplane in point B) and the time (between the 2nd airplane in point A and the 1st airplane in point B) should be less than 4 minutes. These two times should be less than four minutes.
3 - In respect to the vertical distances, the distance (between the 1st airplane in point A and the 2nd airplane in point B) and the distance (between the 2nd airplane in point A and the 1st airplane in point B) should be less than 30 flight units. These two distances should be less than 30 flight units.
My doubts are the following:
1 - In the time distances condition (2nd condition), the time (between the 1st airplane in point A and the 2nd airplane also in point A) and the time (between the 1st airplane in point B and the 2nd airplane also in point B) shouldn't be taken into account? Aren't they relevant?
2 - In the vertical distances condition (3rd condition), the distance (between the 1st airplane in point A and the 2nd airplane also in point A) and the distance (between the 1st airplane in point B and the 2nd airplane also in point B) shouldn't be taken into account? Aren't they relevant?
3 - Finally, are the 2nd and the 3rd conditions necessary to consider an opposite conflict or one of them is enough to spot it?
I'm looking forward for an answer from you and I would like it very much.
Thanks
