The tailplane was fixed to the upper longerons and carried a single elevator surface, mounted on off-set hinges to provide aerodynamic balance.

As aerodynamic balance became more important, this overtaking method became less effective.

Both these surfaces were hinged to provide aerodynamic balance.

The deployment of thrust reversers on a single engine could throw the plane out of aerodynamic balance.

Ailerons, with back set hinges to provide aerodynamic balance were mounted on the upper planes alone.

Described as a masterpiece of aerodynamic balance in fiberglass and stainless steel.

The rudder had a trim tab, but neither it nor the elevators had aerodynamic balances.

Nonstationary flow about a wing-aileron-tab combination including aerodynamic balance (1942)

The ailerons, fitted only to the upper wing, featured aerodynamic balances that extended past the wingtips.

The results of that paper have been extended to include the effect of aerodynamic balance and the effect of adding a control tab to the aileron.
