forward slip
Hi, done some research and have not found an answer suitable. I am aware that the term forward slip means to operate the rudder and ailerons in different directions to overcome crosswinds, how does this help to overcome the crosswinds, this is something I have never tried in my career, any help?

Dash Ocho? So was Bumpy! And A321, of course. But not the deep and dark realm of the A320. . .
If you're not Bumpy, then welcome to the party. I hope you find your answer.
If you are Bumpy, we missed you so.

Why does bumpy insist on using lower-case for the dash 8...? 
-GY
P.S. Amusingly the service ceiling for the A321 is... 39K

aligning non-alignments
crossing controls results in non-alignment of heading and tracking
cross wind results in non-alignment of heading and tracking
crossing controls (adequately) in a cross wind landing results in alignment of heading and tracking
that is how it helps

Thanks you great ginger lump! I already edited it before I saw yer post.
You should try a big sideslip in the crash-8, I think it would do it nicely as it has a big 'ol rudder. Not such a good plan on the Barbie.
You doin' ok now you're a big ol' captain?

Edit: Oops CaptainSmiffy. Have I misidentified you? Just noted your unicycle comment in your profile so, if that was you with the card tricks, then I remember you!
I was your FO I think, not the other way 'round.

One can deliberately cause an aircraft to sideslip by flying crossed controls.
Sometimes one uses such sideslip while endeavouring to maintain a track, eg, during late final to lose an extra bit of height. For this specific use of sideslip, the Americans refer to "forward slip" while everyone else just calls it sideslip.
Done to death in earlier threads if you like to run a search.

If forward slip is side-slip then let me attempt to answer ur Q.
Assuming winds from the left on approach' the nose is cocked to the left to track in.
At flare you give right rudder to straighten. The rudder produces force to the left on the tail.
This force besides acting about the vertical (normal) axis also gives translational force to the left. this translational move counteracts the wind from the left momentarily.
However the swing of the left wing may increase the lift on it & raise the left wing. And also if the float has been long the aircraft will start to drift to the right, so again you will require to dip your left wing
In the end you have applied right rudder & left dip.
hope have been of some help

my god, I can not belive the level of EU pilots here .you should really go back to basic. who taught you to fly a plane?
balanced turn is when the ball is centered...if you Xcontrol you are not in a balanced turn.
next question for you: difference between forward slip and slip?
slip is when you X control but flight straight.
forward slip is when you X control with excess of bank(you skid when excess of rudder), and you drift aways from your track.(used usually to lose altitude)
what's the right technique to enter a forward slip?
first bank the plane over 30 degree
second; apply rudder in opposite direction
how to get out?:
release pressure on rudder
level off your wing
if you can not so this, I suggest you to go with a flight instructor, so he can show you how to do a f. slip.
