This freeware Ground Proximity Warning System gauge for FS2004 can be added to any aircraft that has retractable gear and flaps, and offers the following features: - Clickable switch, with Test/Inhibit function and warning light. - 8 different warning modes, with all the usual aural warnings, like "Pullup", "Sinkrate", "TerrainTerrain", "Windshear" and normal Altitude callouts. - Fully customiseable per aircraft type, by just editing the gauge parameters with Notepad. See README for extensive description. NEW in V3.3: new sound enable/disable handling, configurable sound volumes, a new MasterWarningLight gauge (that enables you using the GPWS with only a small gauge on the main panel window), and more. For users of V2.0 (rcbgp-20.zip): see include file "Upgrade Notes" for upgrade and detailled changes. By Rob Barendregt.

This FS2004 GPWS Gauging mod was recommended to a friend of mine, who had good experiences with it. Having grown frustrated with my own FS2004 experience on a laptop I use for travelling, I decided to try this freeware addition to see if it would make my FS2004 experience feel any more modernized.

Preview screenshot

What I noticed was that by using this Ground Proximity Warning System, I could get used to my bearings a lot easier than I was until now. Capable of being used with any FS2004 aircraft, this also provides a nice few extras such as retractable landing gears and flaps as well as switches, testing functions and even a warning light.

So, did it make my frequent journeys to the ground on FS2004 any less frequent?

A Useful Addition

I’d have to say that yes, yes it did. Using the various features provided across 8 unique warning modes, I was able to make sure that I stopped engaging in low-hanging aviation without realizing it. From offering me useful warnings such as “Windshear!” I was always able to prepare for what was to come before it actually took me by surprise.

One thing that I really liked about this mod, though, was how customizable that it is when compared to the aircraft type it’s used on. This makes it really easy for you to enjoy a much easier flight experience, adjusting to what you need. All you need to do is open up Notepad and start messing around with gauge parameters. It’s really easy and does just take some simple trial and error; anyone could do this.

You can even turn to the ReadMe provided to make sure you get a more thorough understanding of what and when to change factors. Also, another major change that this allows you to do si mess around with sounds volumes and playing times. This allows you to make a more bespoke experience, ensuring that you get to fly the aircraft in the way that you would have hoped for.

The developer of this, Rob Barendregt, has done a fantastic job. Make sure that you get the updates, though, as they offer some nice additions such as space minimization. This allows you to take up less space on the main panel window, reducing the time spent trying to see around this as you fly.

If you are like me and find that FS2004 lacks enough warning for when you get a little too low down, then this is a mod that you absolutely need to think about at least trying!
