A flapping control system (56) for a proprotor assembly (28) of a tiltrotor aircraft (10) includes one or more sensors (46) operable to detect one or more flight parameters of the tiltrotor aircraft (10) to form sensor data. The sensors (46) include a proprotor flapping sensor (60) to detect a proprotor flapping measurement. The flapping control system (56) includes a flapping control module (58) in data communication with the sensors (46). The flapping control module (58) includes a maneuver detection module (168) to detect whether the tiltrotor aircraft is in a maneuver mode using the sensor data. The flapping control module (58) identifies a maneuver flapping threshold associated with the maneuver mode. The flapping control module (58) generates a swashplate command using the proprotor flapping measurement and the maneuver flapping threshold, and sends the swashplate command to the proprotor assembly (28) to reduce flapping of the proprotor assembly (28).
