Does anyone have a correct manual (I say this because I've seen wrong data in some pdf articles where the vrefs for no LE/TE devices were abnormally low) with the stall speed (or Vref which is stall speed * 1.3) tables for zero flaps/slats? I've only seen correct Vref speeds for flaps between 15 and 40 vs weight, so in order to have a clue of the corresponding stall speeds, I simply divided the Vrefs to 1.3. Someone might say: why do you need stall speeds for no flaps/slats? Well, there have been occasions when cannot extend the flaps/slats from neutral (ex: flaps skew, asymmetry, other system failures), so you must land with no slats/flaps at all. I know for sure that there must be a table of stall speeds vs weight for flaps and slats retracted.
