NavData Update Guide

Background and Introduction

Historically, up-to-date NavData has been included with the UK Controller Pack. This data is used by EuroScope to define fixes and ATS Routes. Unfortunately, as of early 2025, this data is no longer freely available to VATSIM UK. While we work on a longer-term free solution, if you have a Navigraph subscription, you can use that to update the relevant files in the UK Controller Pack by following the steps below.

Warning

A Navigraph subscription is required. This guide assumes you use Windows.

Download and Installation Instructions

Downloading the data from Navigraph

  • Go to the 🔗 Navigraph Downloads Page.
  • Ensure you are logged in to Navigraph.
  • Search for the FSNavigator download and click the blue WINDOWS button on that row. Navigraph FSNavigator Download
  • Save the .zip folder to some temporary location where you can find it shortly.
  • Unzip the downloaded folder.
  • Open it, and run the .exe, following the steps presented in the installer.
  • When met with this stage, click Browse... and select a temporary folder to install the files into, such as the one the installer was downloaded into. Navigraph FSNavigator Installer

Installing the files for EuroScope

  • These steps will override the data in the published UK Controller Pack, so first make sure you have the latest Controller Pack installed. Ensure EuroScope is closed.
  • Open the Bin folder within the temporary folder you just used to save the files from running the Navigraph downloader. There should be four files inside.
  • Select and copy the AIRWAY.txt and ISEC.txt files from that folder. FSNavigator Files
  • Navigate to your UK Controller Pack install location (e.g. C:\Users\<username>\AppData\Roaming\EuroScope\UK).
  • Open the Data\Datafiles folder, which should contain 7 files.
  • Paste the two copied files here, overwriting the exisiting files. FSNavigator Files
