Assembly and Rigging Sectional and Final Practice Test

This question is about how different flaps move. A split flap is designed with its trailing edge divided into two sections: the lower portion hinges downward to increase camber, while the upper portion remains fixed to the wing. That creates the distinctive split appearance and mechanism described. The other flap types don’t feature a trailing-edge split: a plain flap deflects as a single piece; a slotted flap uses a gap between the flap and wing to improve airflow; a Fowler flap moves backward and downward along tracks to increase wing area. So the described setup—part of the trailing edge hinging down while the rest stays fixed—fits a split flap.
