Why FS Copilot Is the Best Shared Cockpit Add-on for MSFS 2024

FS Copilot delivers smoother, more stable shared cockpit flights in MSFS 2024 — but its real strength lies in how easily you can define aircraft behavior with simpler, more powerful configurations.

Instead of complex configuration files full of technical parameters, FS Copilot introduces a clean, modern definition format where even advanced logic fits into just a couple of lines. This means fewer bugs, faster setup, and a truly synchronized cockpit experience for every pilot.

That’s why FS Copilot lets you and your friends fly together in perfect harmony — every switch, every instrument, always in sync.

What FS Copilot Does

Connects multiple players to the same aircraft.
Synchronizes controls — yoke, pedals, brakes, trim, lights, and more.
Shares instrument and system states between pilots.
Works peer-to-peer — no external servers required.
Developer interface (launch with --dev) for quick mapping tests.

Quick start

Launch FS Copilot. On first run it copies required files into your Community folder (or copy manually).
Enter your partner’s session code and press Connect.
Start Microsoft Flight Simulator, pick a supported aircraft and enjoy shared flight 🛫

Tip: both pilots should use the same FS Copilot version, the same aircraft and identical YAML definitions.

How It Works

FS Copilot keeps shared cockpit inputs synchronized in MSFS 2024, so each pilot sees the same actions — like a real multi-crew flight.

Low-latency P2P transport, resilient sessions, and a powerful configuration engine keep it stable under real-time load.

Compatibility

Built for Microsoft Flight Simulator 2024. Compatibility with MSFS 2020 has not been tested.

● No accounts required
● Peer-to-peer via NAT hole punching
● YAML definitions per aircraft

For Developers

FS Copilot uses simple YAML definitions to describe how cockpit variables and events sync between players. It’s far more flexible than legacy configs — supporting JavaScript logic, value transformations, and multiple variable types in just a few lines.

This gives aircraft creators more control with less code — and smoother, more stable synchronization for every flight.

- get: L:AS1000_PFD_SelectedNavIndex # NAV 1/2
  set: (>B:AS1000_PFD_1_NAV_Khz_Button_Push)
- get: L:PFD_CDI_Source # CDI
  set: "value < 3 ? `${value} (>K:AP_NAV_SELECT_SET)` : '(>K:TOGGLE_GPS_DRIVES_NAV1)'"
  skp: H:AS1000_PFD_SOFTKEYS_6
- get: A:KOHLSMAN SETTING MB:0, Millibars # BARO
  set: "`${value * 16} 0 (>K:KOHLSMAN_SET)`"
