I was spoting at DEN Sat. afternoon, the winds were 340 @ 34 kts gusting 39 kts. Visibility was 1 and 1/2. All departing aircraft was using RWY 34 and landing 35 R. There were at least 10 aircraft waiting to take the active. My question is why was that the only RWY open for departures? I know the wind was straight down the RWY but why not 35L too? Is the crosswind component too much to handle.

Runways 34 and 35L/R at DEN all have the identical heading of 350 magnetic, so the crosswind component would not have been an issue. As for the wait for takeoff on 34, it would have probably taken just as long for the waiting planes to taxi down the 2 miles to 35L. ATC was using the "pinwheel" design of DEN the way it is supposed to. When the new 16000 ft. 34L is completed, this will be even less of an issue.
I'm no ATC expert, but I would also assume keeping takeoff and landing runways separate is probably the most sure-fire way to eliminate runway incursions, especially at DEN since there is rarely a need to cross a runway while taxiing.

I've been watching the wind reports in the Denver area for the last few days as I've been wanting to go down to New Mexico for the day. The highest I saw was on Friday at jeffco, 40kts, gusting to 55, from 310. That must've been interesting at DEN!

Thanks for the info. When I was heading out ot DEN the winds were so strong that it was blizzard like conditions with the blowing dirt. All ramps at the concourses had piles of dirt everywhere. Im sure that is not good for engines to injest. Jeffco (BJC) winds always seem to be stronger being next to the foothills. I was supposed to fly out of BJC Sat. but no dice. Went up today and was smooth, amazing how the weather changes here in Colorado.

With the "pinwheel" design...
Say winds are from the west, aircraft will land on Runway 8 (on the NE side of the airport). When they pull off the runway, they will be essentially at the terminal ramp. Aircraft will depart on runway 7 (on the SW side of the airport). The end of the runway is also esentially right there at the terminal tarmac. This design minimizes taxi time/distance as well as the possiblity of traffic conflicts. Also due to this configuration, aircraft almost never have to cross a runway.

Thanks a lot for your explanation. But do they have enough with only 2 active runways? Say, in your example, with winds from the west, do they also use 17s/35s or 16/24? If they do, in what condiguration?
