Installing the JSV Flight Logger

JSV Flight Logger Updated 3 days ago

The JSV Flight Logger is JetStream Virtual’s custom-built flight tracking application. It replaces third-party ACARS clients with a purpose-built tool that integrates directly with our website, offering advanced telemetry capture, automatic phase detection, live weather, and a real-time scoring system.

Current version: 1.0.9 — Download from the Logger page

Supported Simulators

  • Microsoft Flight Simulator 2020 — via SimConnect (requires MSFS SDK SimConnect)
  • Microsoft Flight Simulator 2024 — via SimConnect (requires MSFS SDK SimConnect)
  • X-Plane 11 — via built-in UDP DataRef protocol
  • X-Plane 12 — via built-in UDP DataRef protocol

System Requirements

Operating SystemWindows 10 or later (64-bit)
Disk Space~150 MB installed
NetworkInternet connection (offline buffering available for mid-flight interruptions)
SimConnect (MSFS)Required for MSFS 2020 and MSFS 2024. SimConnect is the official Microsoft interface that allows external applications to communicate with the simulator. See installation instructions below.
X-PlaneNo additional software needed — uses the built-in UDP DataRef protocol

SimConnect Installation (MSFS Users)

The Flight Logger uses SimConnect to communicate with Microsoft Flight Simulator. SimConnect is part of the MSFS SDK and must be installed on your system for the Logger to detect and connect to your simulator.

MSFS 2024 users: SimConnect is typically installed automatically with the simulator. If the Logger does not detect your simulator, follow the steps below.

How to install SimConnect

  1. Navigate to your MSFS installation folder. Common locations:
    • Steam: C:\Program Files (x86)\Steam\steamapps\common\MicrosoftFlightSimulator
    • MS Store: C:\Users\YourName\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages\Official
    • MSFS 2024: C:\Program Files\WindowsApps\Microsoft.Limitless_... or your custom install path
  2. Look for the SDK folder: SDK\Core\SimConnect SDK\lib
  3. Run SimConnect.msi from that folder to install the SimConnect client library.
  4. Restart the Flight Logger after installation.
Alternative: If you cannot locate the MSI installer, enable Developer Mode in MSFS (Options → General → Developers → Developer Mode: On). This installs the SDK including SimConnect automatically.

Installation Steps

  1. Visit jetstreamvirtual.com/logger and click Download for Windows.
  2. Run JSV-Flight-Logger-Setup-1.0.9.exe. Windows SmartScreen may prompt you — click More info → Run anyway.
  3. The install wizard walks you through setup:
    1. License Agreement — Read and accept the JetStream Virtual EULA.
    2. Install Location — Choose where to install (default is fine for most users).
    3. Install — Files are copied to your system.
    4. Finish — Tick “Run JSV Flight Logger” to launch immediately.
  4. A Start Menu shortcut is created automatically.

First Launch

  1. Open the Flight Logger from your Start Menu or desktop shortcut.
  2. Log in with your JetStream Virtual credentials (same email and password as the website).
  3. The Logger will automatically detect your simulator if it is running and SimConnect is installed.
  4. If the simulator is not detected, check that SimConnect is installed (MSFS) or that X-Plane’s UDP output is enabled.

Automatic Updates

The app checks for updates automatically — 10 seconds after launch and every 4 hours. When an update is available:

  • It downloads silently in the background.
  • A notification appears when the download is complete.
  • The update installs when you quit the app (or you can install immediately from the notification).

You never need to manually download a new version.

What’s New in v1.0.9

  • New: Automatic passenger and cargo loading based on your flight dispatch
  • New: Enhanced flight scoring with detailed violation tracking
  • New: Improved SimConnect stability and reconnection handling
  • Fixed: ACARS position reporting now maintains connection through network interruptions
  • Fixed: Landing rate detection accuracy improved
  • Improved: Flight phase detection with smoother transitions
