SINGLE ENGINE PISTON-SEP Speed Reference parameters
VR ≥ VS1 V ft = 1.2 VS1
Vref = 1.3 VSo MULTI ENGINE
PISTON-MEP VR ≥ 1.05 VMC
VR = 1.1 VS1 V ft = 1.2
VS1 V ft ≥ 1.1 VMC Vref
= 1.3 VSo Vref > VMC JET VR
≥ V1 VFTO ≥ 1.18VSR V2 >
1.08 VSR V2 > VMC Vref =
1.23 VSRO
WIND & MASS Performance parameters
MMEMOTECNIC-HW & TW are
