Narrative:

I continue to see aircraft being given takeoff clearance on runway 32L T-10 with no regard for type of aircraft landing on runway 09L. The 09L approach path crosses the departure path of the 32L departures. The other morning an A-320 type with cleared for takeoff on runway 32L, as soon as a B757 cleared the takeoff path landing on 09L. It is my understanding that we need 4 miles or 2 mins behind a B757, even if it crosses the departure path. During the daytime it is easy to check aircraft type, but at night time, it is hard to see type of aircraft on final for 09L when holding into position runway 32L awaiting takeoff clearance.
