Delta Dumps Fuel on LAX Children
School kids suffered skin irritation. I had thought 5000AGL was used as a min fuel dump altitude unless you're in danger of augering in.

I overlooked this thread in the Delta forum, there's more info on the link. Destination was Shanghai. The video shows them dumping fuel pretty low.

Just stop. First of all in the US, approval for a heavy a/c departure using clean speeds exceeding 250 below 10K is approved without request (FAR 91.117). Second, they declared an emergency and told ATC the speed they needed to maintain. Not sure what the deal was with the fuel jettison, but they were fine regarding airspeed.

That’s exactly what it means. You don’t even need to ask permission if your clean maneuver speed is over 250 to maintain that speed.

They were "slowing down" to 280. I stand corrected if it's over 280.

So, seems like you're a "minutia guy". What appears to be some secret fuel jettison going on and you're getting spun up over a few knots post declaration of emergency? IDK what their clean speed is. Maybe it's 280, maybe it's less. In the 777F at MTOW it was about 270, but that's a -200 body with a -300 wing. FMC calculated clean speed was usually right at the foot and wasn't particularly comfortable if you had to turn much, so I usually bumped it up 5 knots or so. Maybe it's the same for their a/c. Or maybe the engine situation was resolved using the Captain's emergency authority and a higher speed. Whatever the situation, we don't know what speed they were flying before they declared and once they did, they communicated to ATC what they were doing (at least about their speed ).

True statement regarding 91.117(d), which provides relief for speed restrictions in Class B (below the lateral limits of Class B airspace), C, D, E (below 10,000’) airspaces, Flying a fully loaded heavy, out of courtesy, I advised ATC the minimum speed to be maintained. It helps for their planning purposes when in trail behind a smaller Boeings or Airbuses in busy TMAs.
