PSA Airlines Canadair Regional Jet Systems (PSA-CRJ) Practice Exam

What activates the Flight Data Recorder?

1. Landing Gear Deployment

2. Beacon or Strobes Switch Selection

3. Engines Running

4. Cabin Lights On

The correct answer is: Beacon or Strobes Switch Selection

The Flight Data Recorder (FDR) is an essential component of an aircraft's safety and incident investigation system. It is designed to capture flight parameters and performance data, which can be critical following an accident or incident. One of the primary triggers for the FDR to begin recording data is the activation of the beacon or strobe lights. When the beacon or strobe lights are selected, it indicates that the aircraft is in a state of alert, such as during takeoff, approach, or landing. This selection provides a safety measure, ensuring that the FDR captures critical data during the most crucial phases of flight when incidents are more likely to occur. By recording data from these moments, investigators can analyze flight operations and understand the circumstances leading up to any irregularities. While other options like landing gear deployment, engines running, and cabin lights being turned on are important aspects of flight operations, they do not specifically serve as direct triggers for initiating the recording process for the Flight Data Recorder. Typically, the FDR's activation is closely tied to the operational state of the aircraft regarding its visibility and readiness for critical phases of flight, which is why selecting the beacon or strobe switch is the correct indicator of FDR activation.
