The activation of the Flight Data Recorder (FDR) during the pushback procedure is indeed triggered by turning on the beacon or strobe lights. This step is critical because it initiates the recording of flight parameters prior to taxiing. The FDR is designed to capture essential flight data that can be crucial for analysis in case of incidents or for performance evaluation.

While there are other important actions in the pushback procedure, such as releasing the brakes or communicating with ground control, these do not directly engage the FDR. Setting the flaps is related to flight configurations after the aircraft has been cleared for takeoff and does not impact FDR activation during pushback. Thus, turning on the beacon or strobe lights is the definitive step that triggers the FDR, ensuring that all relevant data is collected from the outset of the flight operation.
