During certification vmcg is established under which condition

VMCG (Minimum Control Speed Ground) is established during certification under the following conditions:

• Critical engine failure: One engine is assumed to fail.
• Remaining engine(s) at maximum takeoff thrust: The operating engine(s) are at the maximum available takeoff thrust.
• Aircraft on the ground: The aircraft is on the runway.
• Directional control maintained using only aerodynamic controls: The rudder is the primary control for maintaining directional control, without the use of nose wheel steering.
• Lateral control maintained: The wings are level, or the bank angle is limited to 5 degrees.
• Aircraft remains on the runway: The aircraft does not depart from the runway surface.
• Specific atmospheric conditions: Typically sea level, standard atmosphere, zero wind.
