Risk,
made visible.
Before every flight, ATOS checks the legal stops — an expired medical or flight review, a missing endorsement, an aircraft overdue for inspection — and cites the regulation. Then it scores the flight against your school's own risk thresholds and shows the factors behind the result. The pilot in command or dispatcher makes and signs the decision.
Check → Score → Review → Decide
Three things, kept separate: what the regulations require, what your school's limits say, and what the pilot in command decides.
Legal stops first — expired medical, expired flight review, missing endorsement, aircraft overdue for inspection. Blocked, with the regulation cited.
Pilot experience and currency, medical, fitness self-check, aircraft airworthiness and open squawks, weather against your school's minimums, and the type of flight.
Within your school's limits, needs review, or outside your school's limits — with the factors that drove the result.
The pilot in command or dispatcher makes the decision and signs it. ATOS records who decided and when.
Measured, respected, never replaced.
FRC doesn't just look at weather. It looks at the pilot — experience, currency, medical, and a private fitness self-check — alongside the aircraft and the flight. The score informs the decision. The PIC always makes it.
Every flight checked before it flies.
