In a turn (or if it makes it easier, sideslip) at an angle of bank of say 30 degrees, what would be the average rate of flow with the crossfeed valve open? What rate would this increase to if the AOB was 60 degrees?
This relates to the metro accident (loss of control at altitude) over Stratford, NZ approx 18 months ago when the autopilot disconnected whilst trying to balance (crossfeed) fuel using a sideslip technique. I am curious as to at what point (i.e how many seconds/minutes) the fuel imbalance would lead to a loss of aileron effectiveness. (hence a loss of control and inability to use normal unusual attitude recovery techniques).
Q: Having read the report, do you think it sound?
