- split flap
: a hinged flap attached to the upper surface of a wing of an airplane usually at the trailing edge to be raised for lateral control or to the lower surface of a wing to be deflected downward for giving increased lift and drag
* * *Aeron.1. a flap that is located on the under surface of the trailing edge of an aircraft wing and that splits away from the wing structure when rotated downward, producing an increase in lift or drag or both. Cf. landing flap.2. a flap that is located on the upper surface of the trailing edge of an aircraft wing and that acts as a spoiler when rotated upward.
