Wing panels that reduce lift and increase drag when deployed.

### More about Spoilers

Spoilers disturb airflow over the upper wing surface. Depending on the design and mode, they can assist speed control, descent and roll control.

After landing, ground spoilers help transfer weight onto the wheels for more effective braking. The functions available in flight and on the ground depend on the installation.
