AIM - AIR 3.11 - Alcohol

Never fly while under the influence of alcohol or drugs. It is best to allow at least 24
hours between the last drink and takeoff time, and at least 48 hours after excessive
drinking. Alcohol is selectively concentrated by the body into certain areas and
remains in the fluid of the inner ear even after all traces of alcohol in the blood have
disappeared. This accounts for the difficulty in balance that is experienced in a
hangover. Even small amounts of alcohol (0.05%) have been shown in simulators to
reduce piloting skills. The effect of alcohol and hypoxia is additive and at 6 000 feet
ASL (1 829 m), the effect of one drink is equivalent to two drinks at sea level. The
body metabolizes alcohol at a fixed rate and no amount of coffee, medication or
oxygen will alter this rate. ALCOHOL AND FLYING DO NOT MIX.
