[quote=Anonymous][quote=Anonymous]You can see flight information for DCA here:

You can set the time back to see flights from earlier in the day. If you set the speed up to 30x you can review pretty quickly.

Looking at a few minutes worth of flights it seems they're flying mostly over the river today and pretty high, relatively. They're mostly over 4,000 ft by Chain Bridge, when things are bad they'll be barely 1,000 ft over Chain Bridge.  Some of the flights seem to be cutting the corner at Georgetown Reservoir but mostly they're staying away from occupied areas.

So I don't know why you're hearing it bad today. I'm in Palisades and it actually seemed relatively quiet today. Wind is out of the north which if anything should be pushing the noise away from you.

The limits introduced after September 11 have all been lifted.

There is no such thing as "the flight path" at DCA. There are currently nine approved departure procedures, you can read about them here:
https://www.faa.gov/nextgen/communityengagement/dc/media/KDCA%205%20Year%20North%20Flow%20Departure%20Analysis.pdf

All of the departure procedures require planes to either fly over the river, or on the Virginia side, at least until the Georgetown Reservoir.  As the linked document shows, a significant number of flights stray by a significant distance from the approved procedure; the FAA doesn't seem to care when that happens. [/quote]

OP here:
this is fantastic information, thanks so much for sharing.

Seeing as the winds were out of the north, now I understand why they were taking off toward the northwest. I think they've typically been landing from the north in recent weeks, so that's why we didn't notice it until yesterday.

Roughly, what percentage of time are planes taking off out of DCA toward the north vs. the south? [/quote]
