• Automatic thrust lever retard system – An auto-retarding thrust lever mechanism
ensures that the thrust lever is at idle whenever the thrust reverser is in transit. In flight,
should a thrust reverser inadvertently deploy, the affected thrust lever is automatically
retarded to IDLE, and locked to minimize asymmetric thrust.
• Emergency stow – A thrust reverser emergency stow system is installed to stow an
unlocked thrust reverser. Selecting the respective UNLK switch/light on the THRUST
REVERSER panel directs 14th-stage bleed air to the PDU to stow the unlocked
reverser.
NOTE
While the UNLK switch/light is selected, 14th-stage bleed air is
continuously applied to the PDU, even if the reverser returns to the
stowed position.
