Timelapse of traffic at Logan
 

Not sure if this is the right forum or if this was already posted, but I saw this on YouTube and wanted to share: http://www.youtube.com/watch?v=3k-xG...layer_embedded

Regardless of where it should be posted, that's a very awesome video. Having lived in Boston for so many years (and having used BOS), I never really realized the coordinaton required.

From the video, it appears that the take-off and landing runways intersect. Is there a reason for this?

Hey that's my home airport too and I even flew home that day. Glad you posted the link!

Thank goodness none of the planes crossing the runway backed up.. when planes are taking off :eek:

Interesting watching the condensed video..

If you look at the FAA diagram you can see the triangle. This is how airports used to be built in the early aviation days, so the runway configuration in a triangle is mostly for historical reasons. Also, remember that there is only a certain amount of crosswind that allow for safe airport operations (the crosswind ratings also depend on plane type), so you need to have runways in the direction of the prevailing winds. If these directions change seasonally, you better have runways that can accommodate these changes or you'll end up with a closed airport during times where the wind is blowing in the wrong direction.


Awesome vid!

Thanks! This is awesome!

As the prevailing winds at PHX are either up or down the Salt River valley, all three runways are E-W. Only very rarely are there crosswinds strong enough from the N or S to cause an issue.

The flow is normally toward the east in the morning and west in the afternoon, but as the video shows (it's facing west and the flow is to the east), that's not 100%.

Good to know that the mountains shield cross winds amongst the valley..

We connected in PHX on our way to KOA on spring break.. Pretty nice horseshoe airport.. bit of a pain walking the entire horseshoe just to get some Japanese.. but I guess we got a bit of a tour.

^ for both!

Is there a reason the small plane taking off at 1:36 in the BOS vid immediately darts off to the right instead of straight like the others?
