What about the hypothetical situation of
Max Angle, that actually happened in his sim?
It is a remote possibility I agree but we had a sim. scenario a while back which basically caused a go-around during a CAT3 (runway blocked I think) and the flaps stick at 3 with the WTB brakes on, slats retract as normal. Not a huge amount of fuel left so divert will leave you pretty short with all that drag. Moving the lever back to 3 runs the slats back out and you get a nice "green" conf 3 displayed.
If the capability is still there......
