Avi Margin puts a paper trail around preflight risk
Avi Margin presents an advisory tool that combines flight, weather, terrain, NOTAM, aircraft, and pilot factors into an explainable preflight readiness brief.
- For
- General aviation pilots and flight schools
- Worth noticing
- The page says unavailable source data is marked “unknown,” never treated as a clear result.
Field notes
The described workflow starts with a route, aircraft, and departure time, then brings together several preflight factors in a brief the page says pilots can explain. A separate six-step assessment records acknowledgements and applies personal minimums; a school-facing view is presented for reviewing activity across instructors and students. The homepage also says unavailable source data remains unknown rather than counting as clear, while the pilot in command retains the decision.
