About AirMark Aviation Services
AirMark Aviation Services is the home of a long-running, personal collection of information on aviation safety — created and maintained by a San Francisco Bay Area flight instructor for the benefit of students and pilots everywhere.
Our Story
This site began as a small set of hand-written notes shared with students. Month after month, the collection grew — safety topics, written exams, and a careful look at the regulations — until it became a free public reference for anyone learning to fly.
The guiding idea has always been simple: understand the why behind every rule, not just the numbers. That understanding is what builds real cockpit judgment.
