|Quoting MD88Captain (Reply 15):
The gusts require a pilot to make adjustments all the way to the ground. I can only guess that this pilot is correcting for a gust close to the ground.
Very good post, however I might add that the attitude of the aircraft could be taken two ways...one as you state above, correcting for a gust at the last moment, OR
he has had this attitude from a further distance out and is just holding it until touch down. there could have been wind shear causing hard roll movements or it could have been stiff but steady wind.
The reason I say all this is is because as you have studied your airliners before, whether MD80's or Boeing's, when there is a bank that is beyond a certain point, the upper or higher wing's outboard most spoilers will temporarily become an additional aileron, if you will, to help lower that wing (which will raise the low wing). Since in the photo of the landing, it's not possible to view the upper right wing in this case, we won't know if the pilot was countering a hard gust correcting with a hard turn to the right OR
just holding this attitude. Wish we could see the upper surface of the right wing and we would know for sure which is the case here. We can see a bit of the tip of the right wing...but there is a fixed trailing edge out there of some 1.5 ft beyond the aileron..so we can't really tell if the aileron is hard up countering the gust.
PS- I might also add that the lower wing in this case is not really that close to the runway...I work on NG's and the tip of the wing when the aircraft is sitting on the ground is almost 20ft. off the ground. Taking that into count, a person can gauge the distance to the ground the tip of the wing is in this case....I estimate it to be roughly 6-8ft.
