The Caravan is a turbine and is certified with a Vmo. It does not have a Vne. Although both speeds provide a margin to Vd they should not be confused because the Vne is literally the never exceed speed whereas Vmo/Mmo is a nominal limit approved to account for the inevitability of some speed excursions whilst operating there.
