109@ full flaps down.

Hi all.

Recently in an airshow a pilot of Fiesler storch showed me the effect of full flaps on the ailerons of a Storch.
At Full flaps the ailerons go both a few degrees down. 
The purpose is to increase ailerons effectiveness at low speed.

The he said me the 109 has the same feature.

I've searched a bit and i found these on the "Flying heritage" facebook page. https://www.facebook.com/flyingheritagecollection/photos/a.10152016899248666.1073741833.13883518665/10152095603113666/?type=3&theater

And on this video of the Messerschmitt foundation you can see @ 8min10 the plane wit flaps fully extended.

IMHO if the developpers implement this feature in the simulator it will be great for the historical accuracy of the simulator ant they, probably, be the first to do that.

The F & G didn't have that feature. It was the E and former models of the 109.

The E and earlier 109s flaps drooped 3 degrees at takeoff flaps and 11 degrees at full flaps.  This doesn't particularly increase effectiveness but does increase low speed lift by increasing outer wing camber.  The limit for droop is total downward deflection of aileron (full aileron travel) where stall becomes inevitable.  These ailerons are known as flaperons (A320 has a verson of them, as do many other aircraft).  They are a compromise between standard ailerons and full span flaps.

But why got the F or G in the Movie had this feature? The Ailerons were about 4 or 5 ° downward while Flaps full extended?

The 109 is taxiing with the stick not centred - the left aileron is down, but the right aileron is up. Note the very different angles of the aileron mass balances.

Uhhh, minor point of order. I flew the F-16 for a few years, and we used the term flaperon. I've been sitting in the left seat of the A319/320 for the last seven years and we have ailerons...not flaperons. There is indeed a slight aileron "droop" when the flaps are extended, but Airbus does NOT use the term flaperon.
