Which of the following is a required preflight action for a remote pilot?

A required preflight action for a remote pilot involves ensuring safety and compliance with regulations, particularly focusing on airspace restrictions. Checking for airspace restrictions is critical because it helps remote pilots understand where they can legally operate their drones, which is essential for avoiding conflicts with manned aircraft and other airspace users. This assessment ensures that the pilot is aware of any temporary flight restrictions, controlled airspace, or other limitations that could impact the safety of their operations.

Although conducting a flight risk assessment is a best practice, and filing a flight plan can be beneficial, they are not universally required actions under the FAA's requirements for remote pilots. Thus, while they may enhance operational safety and efficiency, they do not carry the same mandatory weight as checking for airspace restrictions. Understanding airspace regulations is an essential aspect of remote pilot training and operation, ensuring that pilots maintain safe and legal flight practices.
