Avion Calc

Avion Calc is a calculator designed for pilots to log multi‑leg flight times and track flight duty periods (FDP). It accepts flight duration entries in the HH:MM format as shown on flight plans and can instantly convert them to decimal hours for payroll or maintenance records. Users can input take‑off and landing times, and the app computes the elapsed time automatically, applying configurable report‑time and debrief‑time buffers.

The tool includes a deterministic logic engine that handles the complexity of multiple legs within a single duty day, providing a running total of flight time and ensuring compliance with daily and monthly block‑hour limits. It also supports customizable FDP rules, allowing operators to define their own report and debrief intervals rather than relying on fixed buffers.

Avion Calc is available on Android and iOS platforms, offering a modern interface for flight‑time intelligence while maintaining precision through flexible input formats and unit certainty.
