DOC · Availability

A closed-source Android application.

FlySys Swiss PFD is distributed as a ready-to-install Android app. The source is not public — but the engineering principles, the signal path and the full specification are documented openly across this site.

§1 · Requirements

Before you install

The app runs on a standard Android device. The external IMU is required for the primary flight path; the internal-sensor, simulator and replay modes run without any extra hardware.

§2 · Operation

Choosing a data source

The active source is selected at runtime in Settings — not fixed at install. Switch between live hardware, the simulator and replay without reinstalling.
