What is the FAR requirement for alcohol abstinence before duty?

• A. 4 hours
• B. 12 hours
• C. 8 hours
• D. 24 hours

Answer: (C)

Eight hours of abstinence before duty is required to reduce the risk of alcohol impairment in flight operations. This window gives the body time to metabolize alcohol, helping judgment, coordination, and reaction time be more reliable when you’re on duty. Shorter abstinence can leave you with detectable impairment, while longer periods aren’t mandated by FAR for routine duties (though some employers may have stricter rules). So, eight hours is the standard minimum to help ensure you aren’t impaired at the controls.
