Question 23

When are the speed brakes active?

Answer 23

When the main landing gear is compressed and the speed is more than 72kt with the spoilers armed and the thrust levers at or near idle;
If the spoilers are not armed, the speed brakes will activate when reverse is selected on at least one engine.
Speed brakes will deactivate when at least one thrust lever is at a TLA of 20°.
