Final answer:
The correct answer is c) 8 hours, which aligns with common aviation regulations like the FAA's 'bottle to throttle' rule, giving the liver ample time to metabolize alcohol to avoid impairment while flying.
Step-by-step explanation:
When considering how long to wait before flying a plane after consuming alcohol, it's crucial to ensure that the body has completely metabolized the ingested alcohol to avoid any impairment. Although the legal limit for intoxication is a BAC of 0.08, it is recommended to give the liver enough time to fully process the alcohol. It takes at least five hours for a legally intoxicated person (BAC of 0.08) to sober up. However, regulatory bodies like the Federal Aviation Administration (FAA) in the United States commonly enforce a "bottle to throttle" rule, which is generally 8 hours. Therefore, the correct answer to the question of how long you have to wait to fly a plane after consuming alcohol is: c) 8 hours, It's important to note that some airlines or regulatory bodies might have stricter regulations, so always check the relevant rules before considering flying.
