Russian 767 takes off with spoilers deployed

Well one thing is for sure, he certainly has the aileron into wind for the whole takeoff run, however, just at rotate it does appear he/she centralises the control input. What does the AOM say about aileron displacement at the point of rotate? Also when you say “Current Boeing FCTM” are you saying there is a generic manual? Or is this FCTM type specific?

Are you talking from experience here? Or is this an uninformed guess?

Pacific Flyer is correct. The current Boeing Flight Crew Training Manual says :

“Begin the takeoff roll with the control wheel approximately centered. Throughout the takeoff roll, gradually increase control wheel displacement into the wind only enough to maintain approximately wings level.
Note: Excessive control wheel displacement during rotation and liftoff increases spoiler deployment. As spoiler deployment increases, drag increases and lift is reduced which results in reduced tail clearance, a longer takeoff roll, and slower airplane acceleration.”

Poor technique, with this driver cranking full into-wind aileron from the beginning of the take off roll, resulting in undesirable roll spoiler deployment…….a classic example of how not to do it!

The footage shown demonstrates poor pilot technique. It is likely that the pilot has insufficient rudder input, and is compensating (or trying to) with excessive deflection of the yoke.

This is most undesirable, as it causes drag (increasing the takeoff roll, and risk of a runway over-run in the event of a rejected takeoff), and also causes the afore-mentioned risk of a pod-scrape on liftoff.

Boeing training manuals are quite specific about this, and it is obvious that this pilot was either poorly trained, or ignorant of the requirements of his FOM.

And me, but if one is inclined toward a forum like this, a greater than normal level of aircraft knowledge would be assumed.

You’re right. Most wouldn’t know what a roll spoiler is, but I suppose a very small minority might.

Roll Spoilers were the first thing that came to mind when I saw this vid the other day.

Deano, is the crosswind component dialed into the computer and the spoiler/aileron on that wing raised automatically to compensate?

No mate, no automatic deployment of roll spoiler etc. No wind is ever constant, so it’s aileron into wind as required.

If that’s the case then how would the passengers know that the “roll” spoilers sticking up a bit is even a problem? 🙂

Not sure I would want to be flying in that weather anyway.. I echo the comments about simple roll spoiler as he is working hard with the winds trying to keep the wing level.

So therefore it didn’t take off with the spoilers deployed. If the spoiler handle was armed they would automatically retract when the thrust levers were advanced anyway. What we have here, as someone has said above, is an aileron input that caused the roll spoilers on the same side as the up-going aileron to extend.

This would be fine if you were of a stout constitution and knew what the pilot was trying to do with the spoilers, but not otherwise. I’ll bet a number of passengers were needing a fast underwear change.
As has been said, maybe it would have been better to wait for better weather.

That is exactly what is happening, etc…

My sentiments exactly. The pax seem a bit uncomfortable. Maybe he should have waited a while for better weather? (Although nervous pax can unnerve non nervous pax.)

Had a similar take off to that on a JAT DC9 out of LHR . I don’t know which was more unnerving, the sudden and very noticeable increase in engine noise, and I was in the fwd part of the cabin, the lightening or the spectacle and sound of a pregnant woman nearby slamming the window with her hands and elbow shouting and screaming….did a lot to cheer up fellow nervous fliers. This resulted in a couple of the cabin crew leaving their jump seats very early in the climb out to try to calm/restrain her. The rotten thing was that the weather was just the b****y same in DBV

That is exactly what is happening, nothing unusual about this at all. You will notice at the point of rotate whoever was flying it has to release some of the aileron pressure, this is due to the low sitting engine pods on jet aircraft, thus he/she doesn’t want a “wing down” when on the ground.

from that vid, id say he’s fighting to keep his port wing down throughout that takeoff run
