What you need

The simulator PC

Windows 10 or 11, running one of:
- Microsoft Flight Simulator 2020 or 2024
- X-Plane 11 or 12
The Headingstar Hub (Install the Hub). It includes everything it needs; there’s nothing else to install.
For MSFS: the small SimConnect.dll library that every external MSFS program uses. If you have MobiFlight or the MSFS SDK, the Hub finds it by itself. Otherwise see SimConnect.

iOS or iPadOS 15 or later.
On an iPad: a full panel of six instruments, or up to twenty-four cells per page (6 × 4 on a large iPad), Avionics on the whole screen, and the FlightBook with Apple Pencil.
On an iPhone, held upright: two instruments per page, the flight display, the map, the FlightBook, and the Remote, a touch controller for the navigator. Ideal beside your main screen.
The Live Activity needs iOS 18 or later; the Apple Watch app watchOS 10 or later (Apple Watch and Live Activity).

The PC and your devices must be on the same Wi-Fi network (the PC can be on a cable to the same router).

The Hub listens on TCP port 49275. Windows asks to allow it through the firewall the first time: allow it on private networks.
Guest networks and some mesh or public networks keep devices from seeing each other. Use your main home network.

An Apple Pencil for the FlightBook.
An Apple Watch paired with your iPhone.
An internet connection on the device for the base maps, the weather radar and SimBrief. Download the map ahead for a flight without it (Offline map areas).
A game controller, a button box, a keyboard or a MIDI controller, to turn the knobs and press the keys (Keys, controllers and MIDI).
