2 Reverse Thrust Levers
• controls engine reverse thrust
• cannot select reverse thrust unless related forward thrust lever is at
IDLE.
Note: Reverse thrust lever is blocked at reverse idle position until related thrust
reverser is more than 60% deployed.
Note: Movement of reverse thrust lever into reverse thrust engages locking pawl
preventing forward thrust lever from moving. Terminating reverse thrust
removes locking pawl and restores forward thrust lever movement ability.
