What's Going on here? Climb out with spoilers UAL320

panels 2,3, & 4 are the speedbrakes (1 & 5 are ground spallares)

and lol @ a system where you deflect the handle in the direction normally used to manually extend surfaces in order to disarm the expanded automatic-extension criteria

In this case (Takeoff) it would be amber and flashing immediately right?

Perhaps its a UA cultural thing, but right after the plane broke ground, (likely) the CA disarmed the spoilers. He hit it hard enough and long enough (giggity) that he moved the handle back, thus partially deploying them. It would show up flashing amber in the memo column on the upper ECAM, which neither pilot had in their scan at that point due to the high workload. The master caution chime, light, and caution message will pop up around 20-30 seconds later.

Disarming the spoilers part of our PM flow on flaps up at DL (the flow remains unchanged from NW days, although DL did after takeoff flow identically premerger- a match made in heaven, ruh-right?).

To be fair, a lot of Boeings simply won't tell you anything. "What the hell is that rumbling?! Oh. *click*"

AA965...

Yep on all counts. AA965 can't happen on fifi since they auto-retract with TOGA selection.
 
I would say def the speed brakes, spoilers for turning are 2-5. As mentioned before most likely when the speed brakes were disarmed it probably got moved a little.

What's the technique that you teach to disarm? I usually give it a good fisting. (Giggity)

Reminds me of an interesting case on one of our CRJ-200s. When selecting flaps 20 the airplane would begin to roll to one side. Not dangerously so, but enough that we could tell something wasn't right. We ended up writing it up and having to ferry it down to ATL. I flew the airplane a couple weeks later and looked at the maintenance log. They had to test fly the airplane 5 times before they figured out that as the flaps deployed past a certain point, one of the bonding straps was bumping the underside of the spoilers and deploying one panel just enough that they proximity sensor still thought it was stowed.

We had a 200 doing that at Flaps45... it would take FULL aileron trim to keep the wings level. After doing 4 test flights we finally got a BBD Engineer from Quebec to come on the jump seat. I never heard if they ever figured it out or not.

I remember this being a limitation on the -200 when I flew it. Speedbrakes should be retracted prior to selection of Flaps 45 due to the possibliilty of a roll moment. Never saw that happen or heard of anyone getting into that until just now reading these stories.

Do remember though when the flaps expended in precip was leading to the cables binding around some of the PCU's and becoming stiff or jammed. One of the times you'd see that is when the autopilot would have a hard time making a turn, then maybe all the sudden snap rolling when it gets past the bind. That I have seen.
 
Didn't watch the video. Just wanted to say that the 'Bus also has LAF - load alleviation function. It will deploy spoilers (4 , 5 I think) momentarily if needed depending on how the wing is loaded.
