the wing panel on the down aileron side. This provides speed brake operation and lateral control simultaneously. 

## Winglets 

Winglets are the near-vertical extension of the wingtip that reduces the aerodynamic drag associated with vortices that develop at the wingtips as the airplane moves through the air. By reducing the induced drag at the tips of the wings, fuel consumption goes down and range is extended. Figure 2-17 shows an example of a Learjet 60 with winglets. 

## Canard Wings 

A canard wing aircraft is an airframe configuration of a fixed- wing aircraft in which a small wing or horizontal airfoil is ahead of the main lifting surfaces, rather than behind them as in a conventional aircraft. The canard may be fixed, movable, or designed with elevators. Good examples of aircraft with canard wings are the Rutan VariEze and Beechcraft 2000 Starship. [Figures 2-18 and  2-19]
