Speed Brake Lever

Ground Spoilers Landing

LANDING - Ground spoiler extension occurs automatically upon landing at touchdown of both main gear when:

  • Both thrust levers are at forward idle if the ground spoilers are armed, or
  • Reverse thrust is selected on at least one engine with the other thrust lever at idle if the ground spoilers are not armed

PARTIAL EXTENSION - Partial ground spoiler extension (10°) occurs when:

  • Reverse thrust is selected on at least one engine with the other thrust lever at idle, and
  • One main landing gear strut is compressed.

RETRACTION - The ground spoilers retract when the thrust levers are at idle and the speed brake lever is disarmed, or when at least one thrust lever is above idle.

NOTE

During an autoland, the ground spoilers extend at half speed 1 second after both main landing gear touch down.
