FS2EFB

Transform your tablet or smartphone into a fully functional, real-time Electronic Flight Bag (EFB) powered directly by Microsoft Flight Simulator (MSFS).

FS2EFB is a powerful, three-component bridge system designed to extract high-fidelity telemetry and traffic data from MSFS and deliver it seamlessly to your favorite aviation apps. Whether you are practicing real-world IFR procedures on ForeFlight, navigating VFR with SkyDemon, or soaring in XCSoar, FS2EFB translates simulator data into the exact protocols your EFB expects.

Why Choose FS2EFB? Unlike simple background utilities, FS2EFB operates via a lightweight MSFS In-Game Panel and a companion mobile app. This architecture ensures zero performance impact on your simulator while providing rock-solid, high-frequency data delivery over your local WiFi network.

Key Features

• Comprehensive Telemetry: Transmits highly accurate GPS position (to 6 decimal places), barometric and GPS altitudes, true/indicated airspeeds, attitude (pitch/bank), vertical rates, and ambient wind velocity.
• Live Traffic Injection: See MSFS AI directly on your EFB map. FS2EFB calculates real-time ground speeds, headings, and airborne states for surrounding traffic within a configurable 250 NM range using haversine distance algorithms.
• Universal Protocol Support: Automatically translates MSFS data into industry-standard formats. It features a native GDL90 emulator (ADS-B) on UDP port 4000, extensive NMEA 0183 generation (including proprietary XGPS/XATT and FLARM/PFLAA), and X-Plane DATA* binary packet support.
• One-Click EFB Presets: Forget complex network configurations. Use the built-in preset system to instantly configure ports and protocols for over 15 major EFBs.

Built for Glider & Sailplane Pilots FS2EFB isn't just for powered flight; it's a soaring pilot's dream, fully compatible with advanced glide computers like XCSoar and LK8000. Built-in audio Variometer: Experience incredibly responsive, real-world climb and sink tones directly from your device. Utilizing an advanced audio engine, the app generates dynamic pulsed beeping for lift (scaling in pitch and speed based on climb rate) and solid descending tones for sink, complete with an adjustable dead-band zone.

Zero-Configuration Preset System Stop guessing IP ports, transport modes, and NMEA strings. FS2EFB includes a massive built-in database of one-click presets. Simply select your EFB from the list, and the app automatically configures the correct TCP/UDP transport mode, ports, and data toggles.

• Supported Aviation Apps: ForeFlight, SkyDemon, Garmin Pilot, FlyQ EFB, AirMate, FltplnGO, WingX, OzRunways, Stratus Insight, Sky-Map, EasyVFR, iFly GPS, Air Navigation Pro, AvPlan EFB.
• Supported Marine Apps: Aqua Map, iNavX, iSailor, SeaNav, and i-Boating.

Technical Excellence under the Hood

• Zero FPS Impact: Data extraction is decoupled from the MSFS rendering engine. An intelligent accumulator-based loop ensures that data dispatch is independent of your frame rate. Traffic data is processed via a specialized two-phase queue, guaranteeing that bulk aircraft fetches never cause frame drops.
• High-Fidelity Output: Processes ownship data at a rapid 5Hz. To preserve network bandwidth, traffic updates utilize a skip-frame mechanism to prevent network congestion.
• Battery Friendly: The mobile app features a thread-safe architecture and an auto-stop inactivity timer that safely shuts down the bridge after 30 minutes of no MSFS data, preserving your device's battery life.

Setup Requirements

1. A PC/Xbox running Microsoft Flight Simulator with the FS2EFB In-Game Panel installed.
2. A smartphone or tablet running this companion app.
3. Both devices connected to the same local WiFi network (or using a Mobile Hotspot for the most reliable connection).
