Leaning?

On ZB215 yesterday FAO-LGW the aircraft appeared to be in a right wing slightly down cruise for quite a bit of the flight. The captain said we had a 110 mph tailwind.

I have done this sector probably 70 times and never noticed this before. I conducted my own highly technical research by lying my wine bottle on the tray and it rolled off to the right :hmm:

Can any pro shed some light on this please, as I would have thought any rudder input would have counteracted any tail crosswinds (although I am aware that secondary element of yaw is roll)

Cheers.

Even if there was a crosswind the aircraft would just crab into the wind, it would not bank. Maybe the rudder was not trimmed properly, this could cause a slight bank but I don't think it would cause your bottle to roll to the side:ok:

Thats what I thought Johnny, it would normally crab. There was definitely a right wing down aspect though as I could see a more of the ground than usual and the horizon was higher up.

It definitely made my wine roll and that was before I opened it :O

Ah .... well that answers my unasked question!

Yes Tableview I knew that would be on a lot of peoples minds!.

Just for the record my totally sober travelling companion also noticed it :)
