Recent PHL departure paths

Fri Feb 09, 2018 9:53 pm

Any idea why when PHL is in west flow recently (past 2-3 months), the departure paths have been shifted much farther north so that they go virtually right over land instead of out over the river? Not only that, but frequent use of runway 27R for departures instead of 27L. Both of these combined factors has made living in the area very unpleasant recently. Was looking to see if anyone knew if these changes were permanent or due to something temporary.

There have been no changes to departures in any way. 27R departures are part of a relatively new operation to land 27L and 17 during southerly winds rather than trying to force landing 35 in a tailwind all the time.
I think Big Foot is blurry... It's not the photographers fault. There's a large out of focus monster roaming the countryside.

Do you know about how long this operation has been in effect? Trying to determine if I am crazy or not, because I've lived in this area for about 4 years and haven't noticed an increase in the noise until within the past few months.

Its been around since at least last summer, but as I said its only used during southerly/southwesterly winds so its not more than a couple times a week and even then before new year's we hadn't used it very much for a while. Generally we also only try to use it during heavy arrival pushes, not departure pushes (except yesterday). Unless you're in Essington/Tinicum I highly doubt it would cause any appreciable noise increase since 27R departures are only about 1500 feet farther north than a 27R departure. Otherwise departures are treated the same.

Now I'm curious, would this operation be in effect if winds are from between 180 and 270 degrees?

Generally speaking yes, but not necessarily. If the wind is light we may not bother. As I said it's generally supposed to be reserved for arrival pushes only as working a lot of departures at 27R is more difficult. Depending on the wind we may land 27R and the Liberty Visual 27L approach.
