Whoop Whoop Pull Up! (KATL, 8-23-05)

Wed Aug 24, 2005 9:09 am

Wow, what a ride ... DL 373, MD80 (ship 902, btw), from St. Louis to Atlanta ...

Slightly delayed (45mins or so) due to traffic holds, no surprise on a weekday afternoon to atlanta ... we were lined up for our landing when right about the time the landing gear would come down, we start hearing from the cockpit "Whoop! Whoop! PULL UP!" over and over, and the engines spool up.

We overflew the airport at altitude and the pilot announced he didn't like the looks of a rainstorm and we were going to circle around and try again ...

So we did ... 2nd try, we came on down and right before touchdown, the warning went off again, over and over ... we were slightly right of center and suddenly just slipped to center and sat down - not a hard landing, but a "firm" one ... I'm guessing maybe crosswind and we sideslipped a bit to line up before touchdown?

It was a pretty nice bit of flying, albeit a bit disconcerting with that warning blaring through the cockpit door. If it was THAT loud in row 3, I can't imagine how loud it must have been on the other side of that nice FAA approved reinforced door ...

And lemme tell you, not halfway through the rollout, the skies opened up.

Rain so hard you couldn't see the little lights on the metal stands that mark the taxiways. Constant lightning and thunder. I think we were the last plane down.

Ramp was closed for a good 30mins before we could pull into the gate, and by the time I got my bags (there were only 10 flights listed on the arrivals board!) it had opened up again even WORSE than when we landed - constant lightning all around the ground transportation area, and no planes moving on the tarmac at all ...

I feel for anyone who wasn't as lucky and got to visit somewhere else this evening ...

It was never a "white knuckle" situtation, just certainly not normal.

and I'm damned glad to have made it in before everything cut loose, or I'd probably be typing this from Birmingham or Chattanooga about now ...

Anyone know if the delayed flights circled or diverted?

sounds like that woop woop PULL UP might have been a mech issue as it seems like it was ok to land...unless the computer was reading a microburst somehow!

I'm guessing microburst - we were literally seconds away from getting inundated (the storm hit while we were halfway through the rollout) so I'm sure the winds in the area were blowing all over the place.

Had we been 30 seconds later landing, the runway conditions would have been akin to what the Air France A340 encountered in Toronto.

You have some guts. I would have crapped my pants if I heard the "Whoop Whoop pull up" alert throughout the cabin.
The proper term is "on final" not "on finals" bud...

Well, everyone up in First was kinda leaning out into the aisle looking at the cockpit door, that's for sure. It was clearly audible. I had 3D, which is a window seat, and it was very clear looking outside we weren't out of control or anything ... or, for that matter, sinking at an alarming rate.

It *was* disconcerting however.

That is *NOT* a sound you want to hear in flight.

With the MD-80's, it's hard not to hear any computer noises from the cockpit. The computer voice is no more loud than a TV at moderate volume, but having no engine in first class makes it seems louder than it really is. I'm sure that you heard the altitude callouts, too.

As far as I know, GCAS (Ground Collision Avoidance System) can be overridden and turned off by the crew in case of a false warning, or am I wrong?

Sounds like a very interesting experience, Litz! I'm glad that you didn't have to divert!

There is a possibility that you can ignore the warning but I would be EXTREMELY cautious to even consider such a thing. The correct action would be to react immediately for a warning by leveling the wings and initiate a maximum gradient climb to safe altitude using full thrust. It is more like reflex and at that point you don't start to think what might have caused the warning. Go around and analyze the situation later when there is more time.

Most likely it was strong downdraft which caused the aircraft to descend too fast. The EGPWS will give you "WHOOP WHOOP PULL UP" warning in all these circumstances:

1) Excessive descent rate
2) Excessive terrain closure rate
3) Proximity to terrain and gear not locked down

There is also a lower level alert of all those above when the situation isn't so critical yet. The aural warnings for those three examples would be:

1) Sink Rate!
2) Terrain Terrain!
3) Too low gear!

Best Regards,

I was in the front row of an AA MD80 last week and could very clearly hear the altitude callouts.

Tuesday and Wednesday evenings were a mess for diversions.... lots of planes to Chattanooga, Knoxville, Huntsville, etc. etc. etc....

On Tuesday my flight from MCI to ATL circled over BNA, then circled over Rome, GA. With four minutes to go before diverting to CHA, we were cleared to ATL. On Wednesday, working FNT to ATL, we were held on the ground for nearly two hours due to flow control. Then held en route to ATL, did two turns, then cleared in...

I don't think I have seen flow control delays in ATL like I've seen this summer. We're talking EVERY DAY for 1, 2, 3, 4+ hours..... I've been warning friends who live here... "Get all of your flying done before 2PM. If you're gonna fly after that, don't make any plans close to scheduled arrival time. In fact, just wait until late September to fly."
