Wino or anybody else for that matter...
Could you please explain to me why it is that below a certain speed, the roll authority of the ailerons are no longer able to oppose the secondary roll caused by the displaced rudder?
I would have thought that as the airspeed reduces, both the forces produced by the rudder and ailerons/spoilers reduce at the same rate and therefore the balance of forces is maintained.
But obviously that is not the case. So what are the aerodynamics involved? You say it has to do with the angle of attack. How so??
Thanks.
