Which parameter defines the RAT deployment maximum speed?

Explanation:
RAT deployment speed is limited by the airplane’s overall flight envelope, which is defined by the maximum operating limit speed, VMO/MMO. The Ram Air Turbine must deploy and operate within this envelope, so its maximum deployment speed cannot exceed VMO/MMO. Other speeds refer to different limits: VFE 1 is the flap-extended speed, V window is a configuration-specific speed range, and Vb is a gust/maneuvering speed—none of these set the RAT’s deployment boundary.
