The SPEED BRAKE lever automatically moves to the UP position and the
spoilers deploy.
Note: Following an all flaps up (no flap) landing, the SPEED BRAKE
lever will not move beyond the FLIGHT DETENT and the spoilers
will not fully deploy.
If a wheel spin-up signal is not detected, when the air/ground system senses
ground mode (any gear strut compresses) the SPEED BRAKE lever moves to the
UP position and flight spoiler panels deploy automatically. When the right main
landing gear strut compresses, a mechanical linkage opens the ground spoiler
interlock valve and the ground spoilers deploy.
If the SPEED BRAKE lever is in the DOWN position during landing or rejected
takeoff, the auto speed brake system operates when these conditions occur:
• main landing gear wheels spin up (more than 60 kts)
• both thrust levers are retarded to IDLE
• reverse thrust levers are positioned for reverse thrust.
The SPEED BRAKE lever automatically moves to the UP position and spoilers
deploy.
After an RTO or landing, if either thrust lever is advanced, the SPEED BRAKE
lever automatically moves to the DOWN detent and all spoiler panels retract. The
spoiler panels may also be retracted by manually moving the SPEED BRAKE
lever to the DOWN detent.
