- 105–125 kt
- VREFReference landing speedTarget speed over the threshold, typical value at maximum landing weight.
- 100–120 kt
- VFEMax flaps extendedHighest speed with flaps down. Top of the white arc.
- 161–200 kt
- VMOMax operating speedSpeed limit of a turbine aircraft in knots; higher up, the Mach limit (MMO) applies instead.
