What is going on with aviation security.

No drinking within 8 hours of flightUnited States Federal Aviation Administration regulations for commercial pilots are clear:The FAA's drug and alcohol regulations specifically prohibit pilots from performing flight crew member duties for an airline with prohibited drugs in their systems. They also restrict pilots from "flying or attempting to fly an aircraft within 8 hours of consuming alcohol or if they have an alcohol concentration of 0.04 percent or greater," according to FAA rules. Pilots may not use alcohol "while on-duty or within 8 hours of performing flight crew member duties." Tests include random drug and alcohol testing; testing for a reasonable suspicion of alcohol and/or cause; post-accident drug and alcohol testing; return-to-duty drug or alcohol testing following successful rehabilitation; and follow-up drug and/or alcohol testing. Internationally, rules around alcohol for flight crew members vary by country, with guidance from the International Civil Aviation Organization.
