System Description
9.20.20
MN-FLT-OH-201
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 spoilers retract. The
spoilers may also be retracted by manually moving the SPEED BRAKE lever to
the DOWN detent.
