FCOM NORMAL SOP FCOM DATED 31 may 2012
Landing:
BOTH THRUST LEVERS...................................................... .......................REV MAX or REV IDLE ‐ On dry runway only and if landing performance permits, the flight crew can select and maintain REV IDLE until taxi speed is reached. For any other case, immediately select REV MAX on all reverser levers after main landing gear touches down. The flight crew must select REV MAX if the aircraft is affected by any failure that impacts the landing performance, or if required due to an emergency. A slight pitch up that can be easily controlled by the pilot, may occur when the thrust reversers are deployed before the nose landing gear touches down. ‐ After the flight crew selects reverse thrust, they should perform a full stop landing.
