Hi everyone, I have a general question about runways. In Montreal for
example (CYUL) or anywhere else. What would be a factor making planes
land on Rwy 24L vs landing on 24R. I understand that prevailing winds
play a role in determining if its 24L or 06L, but I cant figure how
they decide to use left or right.

Typically they'll use one for departures and the other for arrivals.
If they're different lengths, they'll usually use the longer one for
departures, since the departing planes usually need more distance
because they're heavy with fuel.

If things are not busy, they'll probably assign individual flights to
the left or right runway based on which involves less taxiing to get
to or from.
