What is the correct departure procedure at a non-controlled airport?

At a non-controlled airport, the correct departure procedure involves following the FAA-approved departure procedure for that airport. This is essential because even though air traffic control (ATC) is not present to manage traffic at a non-controlled airport, pilots are still required to adhere to established protocols to ensure safety and efficiency.

These procedures typically include information about departure routes, climb-out instructions, and any considerations regarding surrounding airspace and terrain. By following the FAA-approved departure procedures, pilots can contribute to safer operations within the vicinity of the airport and maintain situational awareness about other potential traffic.

In contrast, departing without a flight plan may overlook vital safety protocols, and relying solely on the pilot's operating handbook may not incorporate specific local procedures or airspace considerations unique to that airport. Additionally, waiting for ATC clearance is irrelevant at a non-controlled airport, as ATC is not involved in those operations. Hence, the most appropriate and safest option in this scenario is to follow the FAA-approved departure procedure.
