Question

Aircrew members will not fly if any alcohol is consumed within ____ prior to ____

Option 1: 4 hours, flight time
Option 2: 8 hours, flight time
Option 3: 12 hours, takeoff
Option 4: 24 hours, landing

Answer 1

Aircrew members are advised to avoid alcohol consumption for a minimum of 8 hours before their flight time to allow complete metabolization of alcohol by the liver and ensure no impairment during flight operations.

Step-by-step explanation:

Aircrew members have strict guidelines when it comes to alcohol consumption and flight duties. To ensure the safety of passengers and the effectiveness of the aircrew, it's vital that they are not influenced by alcohol while performing their duties. Given the alcohol metabolism rate and the concern for alcohol toxicity, it is recommended that no alcohol be consumed within 8 hours prior to flight time. This guideline allows the liver adequate time to metabolize alcohol and reduces the risk of impairment during flight.

As a reference, the legal limit for intoxication in most areas is a blood alcohol concentration (BAC) of 0.08. Understanding that it takes the liver at least five hours to metabolize alcohol to sobriety for a legally intoxicated person, the "8 hours from bottle to throttle" rule provides an additional buffer. This safety margin is vital in aviation to maintain the highest standards of safety.
