FCOM DSC 27-10-20:
Mechanical control of the THS is available from the pitch trim wheel at any time, if either the green or yellow hydraulic system is functioning. Mechanical control from the pitch trim wheel has priority over electrical control.
FCOM 27-20-20:
Mechanical backup enables the pilot to control the aircraft during a temporary complete loss of electrical power. He does this in pitch by manually applying trim to the THS. The PFDs display “MAN PITCH TRIM ONLY” in red.
FCOM 27-10-10:
Flight control surfaces are all : ‐ Electrically-controlled, and ‐ Hydraulically-activated. The stabilizer and rudder can also be mechanically-controlled.
But still
ALWAYS hydraulically activated.
Thrust is the only method.
