Crosswind landings
Beagle, my understanding of 'kicking off the drift' simply refers to the action, not the finesse! If you don't kick off the drift ie use your feet on the rudder, how else do you do it??
'Kicking' implies a sudden sharp input. Entirely unnecessary - just use a squeeze of rudder to align the aeroplane with the RW as you flare. Exactly as in that A380 video.
Modern aircraft probably compensate for the rolling moment which develops if a large yawing rate is used in swept wing aeroplanes.

Boeing 757/767 Flight Crew Trg Manual allows wing down (max25 kts xwd), crab followed by rwy alignment and crab only up to the ac xwd limitation which for the 757 is 40 kts. Not pretty, but legit. My RAF experience was ‘kicking off the drift’ for most ac and wing down for C130. The 75/76 doesn’t compensate for the roll due to yaw.

Always found offsetting the Cockpit from the centreline a tadge during the approach helped prevent the usual dick-dance trying to regain it during the rollout. BTW, some B737 variants had 5° of castor built into the mains which (unofficially) tolerated a small amount of crab angle during touchdown

oh dear me. The entire aviation world understands the concept of 'kicking off the drift' except Beagle!
Back on topic... Boeing testing the triple...

Thanks for the Vid DD! B747 and B777 doing fully drifted TD's, not aligning in the flare, maybe a hint of heading in the right direction on TD in one of those. Again, would be interested what the Makers certification for X-wind limit landings is? I guess, fully drifted to TD?

OAP. A/L xwd limit 25 kts. The align mode is a sub mode initiated about 500’ which adds some wing down (max aob 2deg) if the crab exceeds 5deg, so a bit of both really. Very rare for lo vis to have much in the way of windiness so i’ve not seen a lot of this going on.
As as for terminology ‘kicking....etc’ is a bit of shorthand and I sort of take the view that no one is going to be using this forum as a definitive teaching aid for technique.

OAP has got the wrong end of the stick, I was NOT slagging anyone off, just trying to have a reasonable discussion.
I related some of my experience to show I was not a 200 hr ppl and was trained by some of the very best quality organisations including the manufacturer of the aircraft I mentioned. ( although I have also operated the 767, quite a bit heavier than the 75). Decrab worked on that too!
I WAS however disagreeing with his statement, paricularly after discussing the issue with close relative, a former Airbus and now 787 training captain.
It it is interest that in “Handling the Big Jets” D P Davies describes removing the drift angle of a crabbed approach ( by pushing it off NOT “kicking “ his words) by co-ordinating the rudder input with aileron to keep the wings substantially level, particularly for podded engines.
Can we not not keep the discussion polite and objective?

Hello BA/BY,
So good of you to return to your topic. I agree that you should keep your discussion polite and objective.
Now, instead of rudely referring to me (or anyone else) in the third person, as you still are, may suggest you are less rude and use the second person when addressing a forum member?
Cheers

The crosswind landing gear function is checked whilst taxying in the B-52. It felt weird to be moving diagonally across the RW at Barksdale whilst looking directly ahead when I experienced it!

The port outrigger apparently on the grass adds an extra dimension. I assume B-52s prefer 200ft wide runways.
Ecce Homo! Loquitur...
Never needed any of that kicking off drift nonsense in the F4.....
