What is the required minimum time before a flight during which alcohol consumption is restricted according to AFI 11-202, VOL 3?

The correct minimum time for alcohol consumption restriction before a flight, as outlined in AFI 11-202, VOL 3, is 12 hours. This guideline is in place to ensure that pilots are fit for duty and capable of performing their responsibilities safely. The 12-hour rule helps mitigate the risks associated with alcohol impairment, as alcohol can affect cognitive functions, motor coordination, and decision-making abilities, which are critical for flying.

This requirement reflects an industry standard aimed at promoting safety in aviation by ensuring that personnel have enough time for the effects of alcohol to diminish, thereby minimizing the potential for impaired performance. This rule applies not only to military operations but is also echoed in commercial aviation practices, emphasizing the importance of mitigating risks associated with alcohol consumption prior to flying.
