BOAC,
CH - a reduction in power once the a/c has unstalled MAY be the only way to control pitch. Read the QRH.
Approach To Stall Recovery
The following is immediately accomplished at the first indication of stall,
buffet or stick shaker.
Pilot Flying
• Advance the thrust levers to
maximum thrust.
• Smoothly adjust pitch attitude*
to avoid ground contact or
obstacles.
• Level the wings (do not change
flap or landing gear configuration).
Pilot Not Flying
• Verify maximum thrust.
• Monitor altitude and airspeed.
• Call out any trend toward
terrain contact.
Note:
*At high altitudes it may be necessary to decrease pitch
attitude below the horizon to achieve acceleration.
I don't see any reference (or requirement IMHO) to reduce thrust initially but there is a reference to reducing it or even rolling the aircraft for nose high recovery. Is that what you meant?
