Hello again Milt,
You have previously accepted that it is possible to have left sideslip or right sideslip with the left engine out, depending upon what combination of rudder and bank angle you are using. As stated in my pevious post, this means that there must be a combination of rudder and bank angle at which the aircraft is not slipping in either direction.
It is all very well for you to repeatedly pronounce that bank without slip is impossible. But how do you account for the situation above?
Can you describe some process whereby the aircraft changes from left sideslip to right sideslip without actually passing through a zero sideslip condition?
If on the other hand you accept that the zero sideslip condition exists, do you believe it be with wings level or with some degree of bank angle towards or away from the live engine?
