Would anyone know the MD 11 vmca and vmcg? Kind of an obscure question but any help would be appreciated.
Thanks
Both speeds depend on Pressure Altitude and OAT, and are given for the 'One Wing Engine Inoperative'-case, VMCA additionally depends on the flap setting.
For ISA conditions (MSL, 15°C), the speeds are:
VMCG: 139kt
VMCA (flaps 15/slats ext.): 128kt
Both, VMCG and VMCA decrease with higher PA and/or OAT, VMCA increases with lower flap settings and decreases with higher settings.

For MD-11 (CF6 engines) the VMCG also changes with engine bleed setting used for takeoff (less VMCG for bleed on). That can be used to get a little more takeoff weight when you are VMCG limited (e.g. Contaminated Runway)
