When evaluating yourself as part of the ADM process, for how many hours prior to flight does the FAA require you avoid alcohol?

• A. 8 hours and enough time to be free from all the effects of alcohol
• B. 4 hours
• C. 12 hours
• D. No requirement

Answer: (A)

In the ADM process, personal factors that affect safety must be actively managed, including impairment from alcohol. Alcohol can dull judgment, slow reaction times, impair memory, and reduce situational awareness—all critical for safe UAS operation. To address this, the FAA requires you to refrain from drinking for at least 8 hours before flight and to be free from the effects of alcohol when you are operating. This 8-hour guideline helps ensure that most of the alcohol has been metabolized and that any residual effects have faded, reducing the risk of unsafe decisions or delayed reactions. Four hours could still leave impairment, while twelve hours is more restrictive than necessary for safety. If you still feel any effect of alcohol, you should not fly.
