Alcohol & Flying
FAR 91.17 explained: the eight-hour “bottle to throttle” rule, blood-alcohol limits, and why hangovers are just as dangerous as intoxication.
Read the alcohol safety guide →Welcome. This site is a growing collection of information on aviation safety — practical guidance, FAR study material, written exams and accident awareness that I have gathered and written during my years as a flight instructor in the San Francisco Bay Area.

Browse the regulations guide →Most general-aviation incidents trace back to human factors — fatigue, alcohol, weather, and complacency. Identifying them is the first step to avoiding them.
FAR Part 91 rules exist for a reason. Understanding why a rule exists makes it stick far better than memorizing numbers.
Every exam and topic on this site is written from real flight-instructor experience, so the questions reflect what pilots are actually asked.
Stay aware of recent general-aviation events and accident reports. Awareness of real-world incidents builds the healthy caution every pilot needs.
Not everything here is cockpit talk. A quiet corner of the site keeps the things that live in a pilot’s pocket instead of the panel — including the wristwatch side of the hobby, where the Nautilus comes up more often than anyone here will admit.
FAR 91.17 requires at least 8 hours from “bottle to throttle”, no operating while under the influence, and a blood-alcohol level below 0.04%. On a hangover, allow far more time.
Regulatory VFR cruising altitudes apply at 3,000 feet AGL and above. Odd 500-foot altitudes (e.g. 4,500) for headings 0–179°, and even (e.g. 5,500) for headings 180–359°.
Supplemental oxygen is recommended on flights above 12,500 MSL and at night above 7,000 MSL. Never gauge your need by how you feel — hypoxia can feel comfortable.
