FDD for Windows

The vNAAATS Flight Data Display as a Windows app, with everything else you need to control oceanic ready at the click of one button.
Download FDD for Windows
Free. Windows installer. No administrator rights needed.
The installer is not code-signed yet, so Windows may say "Windows protected your PC". Choose More info, then Run anyway. Why, and what is being done about it.

About four minutes: what the app does, why it is better than a browser, how to install it (including the Windows SmartScreen message), the one-time setup and how updates work.

What is it?

It is the same Flight Data Display you use in a browser, in its own window with its own icon, plus a small helper that looks after your computer's side of vNAAATS. There is nothing to configure by hand: you answer a few questions once and it remembers.

Why use it?

Always up to date
The display updates by itself, with no new download. When the EuroScope plugin, airline list or font needs updating, the app tells you and asks before it changes anything.
Opens your other programs
Choose your position and it starts EuroScope, VACS and your audio client (Audio for VATSIM or TrackAudio) for you.
One-time setup
Point it at your EuroScope folder and paste your key once. It checks the plugin, saves the key into vnaaats.cfg for you, and never asks again unless something needs attention.
Sign in once
Tick Remember me and your sign-in is kept safely in the Windows Credential Manager on your computer, never on our server.
Its own window
A taskbar icon, and a window you can put on a second monitor, separate from all your browser tabs.
VACS call alert
A headphones button in the display flashes, with a pop-up and an Accept button, when VACS is calling you. It is on already; the app shows you the one VACS setting to tick.
Help built in
The first-time setup shows the how-to video, and the app tells you plainly if a program could not be started and why.

What VACS and TrackAudio are, setting up VACS remote control, answering VACS calls, who spoke last, and the transmitting-aircraft highlight. We highly recommend TrackAudio for the full features.

What you need

  • Windows 10 or Windows 11, 64-bit. (It uses Microsoft's WebView2, which is already part of Windows 11 and up-to-date Windows 10. If yours is missing, the installer fetches it, so an internet connection is needed to install.)
  • EuroScope and the official Gander Oceanic sector package from AeroNav.
  • Your own API key, free at vnaaats.com/get-key for all oceanic controllers (Gander Oceanic controllers can also use ganderoceanic.ca/my/vnaaats). The display opens only while you are connected to VATSIM on an oceanic position. Keep your key private.
  • Optional: VACS and Audio for VATSIM or TrackAudio if you want the app to open them.

How it works

  1. Download and run the installer.
  2. On first launch, play the welcome and do the one-time setup (folder, plugin check, key, your programs).
  3. Load the plugin in EuroScope and open the vNAAATS screen once. The install guide walks you through it, with a video.
  4. From then on: open the app, sign in, choose your position. Everything else starts for you.
Prefer a browser?
The display works in any browser at vnaaats.com/fdd. You then install the EuroScope plugin yourself: see the downloads page.
