Updating the FMS Trainer Navigation Database

Jan 15, 2018
By: Stacy Honda, Marketing Manager

The Flight Management System Trainer (FMST) Desktop Software Program provides interactive and user-friendly familiarization and training for the Universal Avionics FMS. Driven by FMS software, the FMST uses the same navigation database as your aircraft. There are two ways to obtain your navigation database; either from your Authorized Dealer/ Integrator or the UniNet Customer Portal.

The FMST automatically creates a simulated Data Transfer Unit (DTU) in the following destination on your computer: C Drive/ Users/ User Account Name/ My Documents/ FMS Trainer V3/ SBAS FMS Trainer (or GPS Trainer)/ DTU. We recommend creating a shortcut to this folder for easy access. In addition, creating a DTU folder on your desktop or a flash drive containing the navigation database used to update the FMS on your aircraft can be helpful. Be sure to change the FMST DTU location if you copy the "UASC" folder from your flash drive to your computer or use the flash drive containing your navigation database.

Changing the DTU Location

The following steps describe how to change your DTU location:

  1. Select "Configuration"
  2. Select "Application and FMS Options…" from the dropdown window
  3. This will present an options window from which you'll select the "FMS Settings" tab
  4. To set the path to the simulated DTU, either type in the path or use the browse button, and then select "OK." Note: The folder containing the navigation database must be selected and the FMS must be turned off before changing the DTU location.

These steps are demonstrated in the image below:


For each database cycle, be sure to copy the new navigation database into this folder. It's best to delete the old navigation database before copying the new one into the folder. Some file names change between cycles and the old files need to be removed from the simulated DTU. From there, you can start the FMS and load the navigation database with the same procedure as in the aircraft.
