It is obvious that flying airplanes and alcohol do not mix. However, it is
common for pilots to underestimate the lasting effects of alcohol consumption. A
pilot might feel fine to fly, but be suffering from the influence or after
effects of alcohol more than a 24 hours later.
The legal requirements for pilots concerning alcohol consumption is "Eight hours
bottle to throttle", with the additional stipulation which specifies a blood
alcohol content no greater than 0.04%.
Most aviation businesses do not allow their pilots to follow these minimum legal
requirements. Instead, its common for company policy to require 12 or even 24
hours bottle to throttle, with a zero tolerance for blood alcohol content.
The private pilot has the option of what personal policies to follow. For many
people, it is advisable to follow the example of aviation business and adhere to
a higher standard than the legal minimums.
It is also illegal to carry a person under the influence of drugs or alcohol,
with the exception of an emergency or the carriage of a medical patient under

Carriage of Illegal Drugs
It is illegal to knowingly carry narcotics, marihuana, or depressant or
stimulant drugs or other substances on an airplane.
Pilots Involved with Alcohol or Drugs
If a pilot is convicted of anything related to illegal drugs, the FAA may
suspend or revoke that person's pilot's certificate. The FAA may also
impose a 1 year waiting period before that person may reapply to take the
written and practical tests to acquire pilot certification.
This is also true of a pilot who flies while under the influence or knowingly
carries illegal drugs.
If a pilot is involved in a motor vehicle action, that pilot must report the
motor vehicle action in writing to the FAA within 60 days. A motor vehicle
action is basically anything that results from drinking and driving.
Failure to report DUI related actions to the FAA can result in revocation of a
person's pilot certificate and denial for application for one year.
