Hi RRRat,
Thanks for your reply, just getting my head round this now!! So I see what your saying about the thrust line hence the slip, but I just want to clarify my understanding...
Is the Beta target the airbus 'slip indicator' or a min drag indicator?
Not quite sure I understand why with bank into the live engine you'd have min control drag, as with neutral aileron and thus a slight lack of rudder you'd have less control deflection into the airstream, however would I be then correct in assuming you'd have a constant heading but not a constant track due to the slip? I suspect I haven't got this!
Thanks again,
A
