A nd to carry on from John`s visual aid, if you turn the paper upside down you can see the effect of Anhedral, Di`s Welsh sister...!
Just a couple of point`s to add; be very careful if you do any prolonged, or extreme sideslips with flap down, as you may find the nose suddenly drops, stick comes back, and the a/c may flick, as the effect of flaps may blank off the fin/rudder;;
Also, if its a twin with fuel in the wings, the fuel outlet on the inside wing may become uncovered, and it may stop the inboard engine.....This may well be somewhat eye-watering, and require a change of underwear upon recovery....!!!!
