Lots of go arounds, misses, abandoned approaches, holds going into KDFW right now due to wind shear and several microbursts off the approach and departure ends. Minus 25 kts at all approach ends. Bumpy stuff all altitudes in the terminal area. Nasty night in the Metroplex.

Or, as we like to call it, spring in Dallas   Although I hear this one's been windier than any that my family can remember. Back in about 1994 we had 5-6 straight Friday and Saturday nights with tornado warnings in the city. Grapefruit sized hail, wicked winds, tons of shear. Tis the season in jolly ol' Dallas!

Looks like the storm that just passed through had cloud tops around 45-50,000 feet with a mesocyclone in it. It is over Collin County now. Huge storm up in Wichita Falls, 55,000 foot tops with a tornadic signature. More out to the Metroplex's southwest toward Brownwood with some storms between 50k and 60k foot tops with large hail.

Exactly. People get all freaked out about 50 mph winds...in Oklahoma and Texas in the spring and summer...that is a normal breeze. Last week here in OKC we were running about 40 mph sustained with gusts up to 70 mph...with clear blue - okay not blue since the dust and smoke hazed everything over - sky.

Just another day in the Southern Plains. Wouldn't live anywhere else.

It's not the 50 kts that's interesting, it's the +/- 50.

Some diverts to KAUS. One American Eagle declared an emergency due to severe turbulence and headed to Ft Worth. Departures beginning slowly but none headed east. Runways now being checked for debris. Still having gusts to 36. Baggage cart reported on a taxiway.

They're down to single stream departures. 20 aircraft on each side of the airport, alternating, 5 miles spacing. God it might be a couple of hours before #40 gets off.

Thanks to that comment, I learned DL is sending a 757 to AUS now on a regular basis. Flightaware is our friend.   

Thanks!

Tell me about it...just after takeoff from KDFW tonight, I hit severe turbulence from 1500' to FL240 in my MD-80 en route to McAllen (KMFE). Although the storms had passed through the area and nothing of significance was showing up on the radar in front of us, the wind shearing off the storm sure got my attention. In over 19,000 hours in the air this is only the third time I can say it was severe turbulence. And to think I was supposed to be in KSTL last night, I guess I shouldn't complain too loudly.

Very interesting, Glenn.

I'm not sure what time you left, but I started listening around midnight CDT, and planes were reporting smooth climbouts after 2000' MSL. A couple of planes hit some moderate chop below 2000', but more often than not, they were smooth all the way out. Bad luck!

Nice to hear a report from the flight deck, thanks!

Cheers,
Cameron

Captain, can you give a description of the effects of severe turbulence you experienced last night. If I am ever in it, I hope it's in a MD-80 as we know how they are built

A few weeks ago I flew DCA-DFW and approach in to DFW was the windiest I have ever been in...you could just feel us getting thrown around like I have never felt. Expected the hardest landing of my life...amazingly, quite the opposite. I was very impressed...

Of course, I then rented an SUV and almost got blown off the road cruising down 183!

Some showed FL650 before things began to settle down last night. I believe 65,000 is the highest the NWS radar will indicate echo tops, as only the SR-71 would need worry about anything above that. I know that sometimes the blow-off anvils of CBs will affect the signature, but I think Texas NEXRAD bases are pretty accurate.

That sounds pretty scary! A lot of rotation up there last night. How long was your climb, and what was the effect on controlled flight?

To put it bluntly, we were hanging on for all it was worth. We got airborne just after 2200 hrs local time after the storm had supposedly passed through the area. Although there was nothing of real significance on the aircraft radar beyond some light precipitation, once we hit the base of the clouds all hell broke loose. Up and downdrafts of 1000'-1500' per minute, airspeed variations of +/-50 kts in less than five seconds, the autopilot was unable to keep up with the violent changes in attitude, loose items were flying around the cockpit, the aircraft was rolling left and right 30-40% in a matter of seconds ...it was a trifle more excitement than I really wanted at that hour of the night. Unfortunately Mother Nature had a different idea and we got to "enjoy" this roller coaster ride for what seemed like an eternity (it was actually about 20 minutes). My first officer was kind enough in the middle of this to suggest that I wouldn't need to go to the gym the next morning since I was definitely getting a workout this evening. Since I was hand flying the aircraft, the arm and leg muscles were getting a wee bit sore. As I had expected a bit of bumps on the climb out (a slight understatement as it were), I had told the passengers and flight attendants to make sure that they had the seat belts fastened. Fortunately for a change everyone listened to my advice and as such there were no injuries on the other side of the cockpit door. After we exited this slightly bumpy departure, I was informed by the flight attendants that I probably got the record for number of passengers who availed themselves to that little bag in the seat pocket in front of them.

As I nursed my sore muscles and back after the autopilot could take over, I refected on the strength of the various Douglas airliners I have flown throughout my career. From the DC3 through DC9, all have been built like tanks and I have never doubted their abilities to withstand anything I could throw at them. Although I have found both the Boeing and Lockheed aircraft that are in my logbook to be equally capable, there is something that Douglas aircraft that just made me appreciate their inherent strength. Although N483A has 65402 hours and 34076 cycles on her, she performed in the best Douglas tradition...safely and reliably. Thanks Don Douglas, you really knew how to build airplanes to last through anything. And hopefully in the remaining 12 years of my career I won't get to test them out in this manner again.

TWA Captain -- thanks for that. Added to my RR list!

I know for you guys in the front office that is a part of the job and you know how to handle it, and that's why we are glad you do what you do... but honestly a situation like that must creep towards being a bit frightening -- even for the most alpha-male pilot. Do PIREPs ahead give any real indication of what you are heading into, and does that change your thinking about proceeding to take off?

Those parameters you gave sound pretty bad. At what point does something like that become unsafe? I heard a regional knocked off the approach due to the severity to turbulence and diverted to Fort Worth (not sure if that meant Meacham, Carswell/NAS Fort Worth or Alliance -- or just holding over Fort Worth).

While intermittent moderate turbulence (as the technical definition of "moderate" will likely meet the general definition of heavy/rough for passengers) can be quite unnerving for the people in the back, an extended period of severe would be terrifying for many -- especially 20 minutes worth. How do you reassure the passengers through that?

Spring/summer time in tornado alley must be a hard day at the office!

Wow, thanks for the detailed description. I was trying to picture that in my mind and it still is scary to think about it. To add to the great questions of MileHighOffice, how can you even keep track of the instruments in those conditions? Hand flying, did you ever get concerned about overstressing the airframe with the varying speed changes? Would there be and special checks required of the aircraft after?

I personally fly smaller aircraft and my heart always takes off in turbulence, and the first thing I always do is make sure to be below Va (maneuvering speed for those non-pilots). Is it similar in a big rig?

I've flown on N483A a few times (ELP-DFW comes to mind).

Worst landing for me was going into DFW on a E145 in this type of weather.

Me too, but on a CR7 out of HSV (via a diversion in to GGG while DFW was closed due to the weather)
