• the speedbrake lever moves to UP and all spoiler panels extend if both
reverse thrust levers are raised to the reverse idle detent.
• the speedbrake lever moves to UP and all spoiler panels extend if above
85 KIAS with both throttles at idle.
In the air:
• the speedbrake lever moves to DOWN and all spoiler panels retract if
either throttle is advanced to high thrust or the airplane reaches a high
