agree with all that (selected recommended, delta Vref...)
when i say fly VLS I mean PFD VLS (which is the same as VREF conf full plus delta vref, I think)
you are right about slats and flaps at zero: use flap 1, it says. BUt nothing happens if you select up to flap 3 on the spur of the moment, since the result is the same (nothing moves).
So if you are in a very bad scenario typical of a command training simulator where they push you to the limits (such as flaps and slats jam with an engine failure and smoke in the cockpit and incapacitade FO and...), it is most useful to know that all you have to do is fly the VLS (PFD) and land, and that normaly you will have enough runway.
