A question for pilots
a situation:
we have an A320 and B738 , both same loaded both in same condition, both same distance from airfield, both on same wind conditions, both same FL on route both same speed at the moment. Both must land.
which will touch the ground first?
PS: i know the question is strange but anyway

i wanted to know who has better "glide/speed" performances
If two such aircraft are gliding, one is going to make the runway, the other is not - because the first glider blocks the runway!!
I could have said that under the law of gravity, having collided, they will both hit the ground at the same time.
Airliners don't glide all the way to the runway if for no other reason than it goes against their stabilised approach criteria.
Why not just aim them at each other and let the TCAS decide - one will go down and that will be the number 1.

Straight answer - whichever the controller decides to put first. And that will probably depend firstly on the overall traffic situation if the are other aircraft around, perhaps on the controller's perception (whether right or wrong) of the relative performance of the aircraft, and less on the types involved or their loading.

If you were comparing the 320/757 - the 320 wins every time. I am not that familiar with the 738, so.......
Generally speaking, the Airbus will have a faster profile and should beat the Boeing. That said, it depends on company policies on speed control and cost indices.
I also don't know if the 738 has the same screen speed limit as the 757. The Airbus isn't limited - please don't start the I wouldn't go fast argument - I am only stating fact.
Personally, I would be happy taking a 320 in to 15 miles at 340kts (provided I am level at that point) and it would still slow down and configure without taking cheese.
I do know that these new 170 to the threshold speed requirements are proving a little challenging if you don't have your wits about you. About time for more co-operation between maggot controllers and maggot operators I guess

Personally, all things being equal, whoever calls first gets to be number 1. Unless one is obviously going faster than the other one. But if both have called one after another before I get chance to reply, then whoever sounds nicest!!!

If you are using Jeppesen charts, you will find it very hard to know what class of controlled airspace you are in a lot of the time in Europe below FL195.
Why worry about speeds? in the approach environment, to split the aircraft in trail is going to take a more than 60Kt which penalises the second aircraft quite a lot if ti has to fly in from 30nm + at 180 Kt or less.
A 20 degree heading split puts 5nm between the tracks after 15nm and Bob is your Dad's brother!!
Proceduraly, first to call gets the lower level - essential to revove the confliction and the sequence is thus set.

I think the original poster was more interested in glide / performance, however badly phrased, rather than the invaluable list of techniques on how to sequence 2 aircraft
