Shadrach Posted February 24, 2019 Report Share Posted February 24, 2019 Trinity Bay East of Houston. Cargo flight. Initial reports read like an airframe failure. RIP. Thankful it was over water. https://www.cnn.com/2019/02/23/us/texas-atlas-air-cargo-jet-crash/index.html Quote Link to comment Share on other sites More sharing options...
Hank Posted February 24, 2019 Report Share Posted February 24, 2019 The article said they have found human remains. Also said the water runs up to 5' deep, before becoming mud. It's duck hunting territory. Sad . . . . Quote Link to comment Share on other sites More sharing options...

Yetti Posted February 24, 2019 Report Share Posted February 24, 2019 There was a front line coming through. Other planes in the area were diverting around weather. Quote Link to comment Share on other sites More sharing options...

ArtVandelay Posted February 24, 2019 Report Share Posted February 24, 2019 Here's the radar depiction just as Flightaware was showing a 7000 ft drop about 1238 CST. I guess trying to go through the gap, but from radar looks like a northern jog would have avoided all of it instead of going around the edge. You got the next one?Tom Quote Link to comment Share on other sites More sharing options...

N201MKTurbo Posted February 25, 2019 Report Share Posted February 25, 2019 What if it didn’t have anything to do with the weather? What if it was like Value Jet and some product caught fire or exploded? Quote Link to comment Share on other sites More sharing options...

Scott Dennstaedt, PhD Posted February 25, 2019 Report Share Posted February 25, 2019 Upon closer examination of an unfiltered NEXRAD loop, you can see what is a secondary line of weak returns (marked by the yellow dashed line) that moves through and ahead of the line of convection. This looks like the radar picked up the cold front as it pushed east-southeast. Could be a coincidence, but this line of "frontal" returns likely reached the aircraft about the time it was in that steep descent. The convective line falls apart pretty quickly once that passes through. Here is the loop...notice how that secondary line moves through the other returns. 1 Quote Link to comment Share on other sites More sharing options...

Scott Dennstaedt, PhD Posted February 26, 2019 Report Share Posted February 26, 2019 Just spoke with the Warning Coordination Meteorologist with the National Weather Service in Houston/Galveston. As I suspected, there wasn't a microburst signature evident - the accident and timing were too far away from the location where the plane went down. The only other weather-related explanation would be some significant turbulence during descent as the frontal boundary moved through the aircraft's flight path and caused the freight to shift. 2 Quote Link to comment Share on other sites More sharing options...

Scott Dennstaedt, PhD Posted March 12, 2019 Report Share Posted March 12, 2019 More info here: https://www.ntsb.gov/investigations/Pages/DCA19MA086.aspx Specifically it says, "Also, about this time, the FDR data indicated that some small vertical accelerations consistent with the airplane entering turbulence. Shortly after, when the airplane’s indicated airspeed was steady about 230 knots, the engines increased to maximum thrust, and the airplane pitch increased to about 4° nose up. The airplane then pitched nose down over the next 18 seconds to about 49° in response to nose-down elevator deflection. The stall warning (stick shaker) did not activate."

I can see a similar formation going through the line of clouds to the southeast. In fact, it looks almost identical. Could there be two frontal margins like that?

I'm hoping they changed it because they realized the same thing would be thought by a lot of people. 280kts everything stable. Suddenly add full power, pitch up 4 degrees then immediately pitch down 50 degrees. I'm not sure what to make of that 2 Quote Link to comment Share on other sites More sharing options...
