What is the minimum time after consuming alcohol that a crew member must wait before operating an RPAS?

The minimum time a crew member must wait after consuming alcohol before operating a Remotely Piloted Aircraft System (RPAS) is 12 hours. This guideline is in place to ensure that the individual's blood alcohol concentration (BAC) significantly decreases, reducing the risk of impaired judgment, reduced coordination, and slower reaction times, which can compromise safety while flying.

The 12-hour waiting period is established to align with aviation regulations and safety standards that emphasize the importance of maintaining a clear mind and full physical capability when operating any type of aircraft, including drones. This measure is crucial for ensuring the safety of not just the crew member but also the aircraft and any individuals or property that might be affected by its operation.
