Whether An Airline Pilot Or A Recreational Flyer, Alcohol And Drugs Just Don’t Mix With Flying

Piloting an aircraft under the influence of alcohol or drugs is obviously a stupid thing to do, and the FAA addresses this in FAR 91.17. The rule starts by saying a pilot may not fly in less than 8 hours after consuming alcohol. Of course, 8 hours may not be enough time to “sober-up,” so the FAA adds that if the blood/alcohol concentration is .04 or greater, it is also against the rules to fly.

If a pilot is using any drug that affects the pilot’s faculties in any way contrary to safety, the FAR says to stay on the ground. The kicker here is that the rule is not simply referring to illegal drugs. Prescription medication, and many over-the-counter medications (Marijuana?) can render a pilot unfit to fly under this rule. Sport pilots…pay attention; this rule applies to all pilots whether or not they hold a medical certificate.

This regulation also affects the pilot’s decision to carry certain passengers. A pilot may not carry a passenger who “appears” (emphasis added) to be under the influence of alcohol or drugs. There are no time limits or blood/alcohol measurements in the passenger part of the rule. However, the passenger alcohol and drug rules do have certain exceptions for emergencies and the transportation of medical patients.

It is interesting to note that the violation of the passenger rule does not get the passenger in trouble; the feds go after the pilot. This is why we occasionally hear about airline captains making an emergency landing to get rid of an intoxicated passenger.

As we look at all GA accidents and the various causes it becomes apparent that alcohol and drugs are not a large factor, but they do occur. In the realm of sport aviation, the lack of a regulatory requirement for a medical certificate could lead a person to think that the rules of medications and drugs don’t apply to them. While the rules for sport pilots don’t specifically name medications or drugs that prohibit a flight, it’s clear in the regulations that the common sense of fitness for flight is regulated for everyone.
