On the Avanti II these flaps automatically deploy in concert with the main wing flaps.

Typical applications include the formation of skins, wing flaps, access panels, and sections of fuselage.

This reduces the load on the tailplane, even when the flaps are deployed, by reducing the pitch-down moment created by the deployment of the main wing flaps.

The Boeing 727 Operations Manual specifies that speedbrakes are not to be operated in flight with wing flaps extended.

An actuator is operatively coupled to each of the flaps, such that each actuator can selectively vary the flap of its associated inlet guide vane.

In one embodiment, the inlet guide vanes each include a pivotably mounted flap that is variable independently of the flaps of at least some of the other inlet guide vanes.

If that’s not enough, the new Kyosho Spitfire also includes functional split flaps with the look and feel of the flaps on the full-size aircraft.

As all Standard Class sailplanes, the ASW-28 does not have flaps or other lift-enhancing devices.
