The Hangar

The operating system for your airplane: maintenance, currency, squawks, flight log, oil trends, and checklists, all in one place that nags you before anything goes overdue.

The demo is a real Cardinal (N89SF). Poke at everything. Nothing saves to an account until you have one.

What’s inside

Requirements that nag you first

ADs, inspections, registrations, databases, and pilot currency, counted down on two clocks at once (calendar and tach or Hobbs hours), with a projected due date from how you actually fly.

Flight log built for the hangar

Quick tach + Hobbs entry, oil before/after, and a flight time that figures itself out. Spreadsheet view with every column when you want it.

Oil trends that mean something

Cumulative consumption per oil cycle with a best-fit burn rate, R², and dipstick error bars. Interactive, zoomable, and it resets at each oil change.

Squawks, ready for the annual

Track discrepancies with airworthiness flags and photos so you walk into your annual with a complete list. Fewer surprises, not a blank-check inspection.

Checklists, author once

One source of truth compiles to a byte-perfect Garmin G3X .ace, an offline phone runner, and a printable kneeboard card, with a linter that teaches good design.

The numbers you actually run

A performance & abort calculator fitted to your POH points, a conditions solver (density altitude + wind components), and an oxygen-duration planner for the flights where it matters.
