Online Flying Networks
VATSIM and IVAO are online networks that provide live air traffic control and other virtual pilots in real-time. Flying on these networks adds a whole new dimension of realism to your flights.
What Are These Networks?
| Network | Description |
|---|---|
| VATSIM Virtual Air Traffic Simulation Network |
The largest online flying network with 100,000+ members. Volunteer controllers provide realistic ATC services worldwide. Free to join. |
| IVAO International Virtual Aviation Organisation |
Similar to VATSIM with a strong European and South American presence. Includes a built-in training and examination system. Free to join. |
Getting Started
- Register on your chosen network’s website
- Download the pilot client:
- VATSIM: vPilot (for MSFS/P3D) or xPilot (for X-Plane)
- IVAO: Altitude (unified client for all simulators)
- Configure your callsign — Use your JetStream Virtual callsign for consistency
- Review the network rules — Both networks have codes of conduct you must follow
- Practice offline first — If you’re new to ATC communication, practice your radio calls before going live
Using vmsACARS with Online Networks
vmsACARS works alongside network pilot clients without any conflicts:
- Start vmsACARS first, then connect to the network
- Both applications read simulator data independently
- vmsACARS will track your flight regardless of network connection status
- If you disconnect from the network mid-flight, vmsACARS continues tracking
Radio Communication Basics
When flying on a network with ATC, you’ll use standard phraseology. Here’s a quick reference:
Before Pushback
You: “Schiphol Delivery, JSV042, stand B24, information Alpha, requesting IFR clearance to Kennedy, flight level 350.”
ATC: “JSV042, cleared to Kennedy via BERGI 3S departure, flight level 350, squawk 4521.”
You: “Cleared to Kennedy, BERGI 3S, flight level 350, squawk 4521, JSV042.”
ATC: “JSV042, cleared to Kennedy via BERGI 3S departure, flight level 350, squawk 4521.”
You: “Cleared to Kennedy, BERGI 3S, flight level 350, squawk 4521, JSV042.”
Pushback & Taxi
You: “Schiphol Ground, JSV042, stand B24, request pushback.”
ATC: “JSV042, pushback approved, face east.”
You: “Pushback approved, facing east, JSV042.”
ATC: “JSV042, pushback approved, face east.”
You: “Pushback approved, facing east, JSV042.”
Tips for Network Flying
- File your flight plan on the network before connecting — most pilot clients let you import from SimBrief
- Listen before transmitting — when you first tune a frequency, listen for a moment to understand what’s happening
- Don’t be afraid to ask — controllers are volunteers and generally happy to help new pilots
- Use “Say again” if you didn’t understand an instruction — it’s better than guessing
- Be patient with delays — busy airports may have departure queues, just like real life
