vRAAS for MSFS

Enhance your flight simulation experience with vRAAS, a virtual Runway Awareness and Advisory System designed to replicate real-world RAAS functionality, delivering runway alerts and advisories directly within MSFS. Every feature operates exactly like its real counterpart and can be easily customized or disabled to suit your preferences.

What’s new in v1.3

Runway Overrun Prevention (ROP) — predictive stopping-distance alerts during landing. If current braking and reverse thrust won’t stop the aircraft on the remaining runway, ROP triggers a “MAX BRAKING! MAX REVERSE!” callout. See the ROP column in the Aircraft Compatibility List for supported aircraft, or watch the official trailer.

Key Features:

Full Compatibility: Works seamlessly with all airports, including add-ons, and supports all aircraft types—no configuration required.
In-Sim Text Display: Displays alerts on the PFD/ND (see limitations below).
Runway Overrun Prevention (ROP): Predictive stopping-distance alerts during landing, prompting maximum braking and reverse thrust when needed. New in v1.3.
Effortless Setup: No manual setup needed—simply install and fly.
Auto-Updating: Stay up-to-date with automatic software and configuration updates.
Automatic Aircraft-Specific Configurations: Automatically downloads aircraft-specific settings.
Multiple Voice Options: Choose from multiple male or female voice callouts for a personalized experience.
Highly Customizable: Tailor the system settings to your preferences with ease.
Convenient Automation: Includes options for auto-start, auto-close, and minimize-to-tray functionality.
No Performance Impact: Enjoy realistic alerts with no noticeable effect on FPS.
Flexible Audio: Select any Windows sound output device for audio alerts.
Built-in Self-Test: Ensure functionality with a reliable self-test feature.
In-Cockpit Controls: RAAS INHIBIT or FLAP INHIBIT switches in your cockpit are linked to vRAAS.

Known Limitations:

Experimental PFD/ND Text Display: The text display on the PFD/ND is currently experimental and may be affected by future MSFS updates.
TOO FAST Callout Limitations: Due to MSFS constraints, the TOO FAST warning is only supported on certain aircraft.

Simulator Compatibility:

vRAAS is fully compatible with MSFS 2020 + MSFS 2024.

Aircraft Compatibility List

Runway Overrun Prevention (ROP)

vRAAS ROP mirrors real-world behavior — for Airbus aircraft the callouts match the Airbus ROPS specification (see Airbus Safety First — Further preventing runway overrun), including the “Step 2” and “Step 2+” rollout alerts below.

On Approach (below ~400 ft AGL)

Advisory that the runway would be too short if wet:
“IF WET: RUNWAY TOO SHORT”
Runway Too Short — Caution (Airbus)
Dry landing distance exceeds runway length available (amber):
“RUNWAY TOO SHORT”
Runway Too Short — Warning (Airbus, below ~200 ft)
Landing distance still exceeds runway available (red):
“RUNWAY TOO SHORT”
Overrun — Go Around (Boeing)
Landing distance exceeds runway available — commands a go-around:
“OVERRUN! GO AROUND!”

On Rollout (above ~30 kt)

Max Braking (Airbus, Step 2)
Overrun risk detected without braking applied:
“BRAKE! MAX BRAKING! MAX BRAKING!”
Set Max Reverse (Airbus, Step 2+)
Braking applied but reverse thrust not yet set:
“SET MAX REVERSE!”
Keep Max Reverse (Airbus, 30–80 kt)

Autobrake Monitoring (new in v1.3)

Autobrake Off
Warns if the autobrake disengages during rollout above ~33 kt — useful to catch accidental disarming before reaching taxi speed:
“AUTOBRAKE OFF”

Why Choose vRAAS?

Compared to other RAAS add-ons on the market, vRAAS offers the following benefits:

RAAS display on PFD/ND for many aircraft
View RAAS alerts directly on your PFD/ND, enhancing in-flight awareness.
Runway Overrun Prevention (ROP) on supported aircraft
Predictive stopping-distance alerts during landing, shown directly on the PFD alongside audio callouts.
Automatic, aircraft-specific configurations
vRAAS automatically downloads and applies specific configurations for each aircraft—no setup required.
Full automation, no interaction required
Enjoy a fully automated experience from start to finish, allowing you to focus entirely on your flight.
Detects runway-specific approach angles, avoiding “TOO HIGH” alerts
Avoids false “TOO HIGH” alerts by recognizing steep approach angles at specific airports, such as London City.
Real-time altimeter calls based on flight area transition altitude
Receive accurate altimeter setting reminders tailored to the transition altitude of your flight area.
Distinct sound levels for advisory vs. caution alerts
Just like real counterpart, alerts are differentiated by volume, with cautions louder than advisories, for immediate recognition.
Integrated with in-cockpit switches for enhanced control
Directly control RAAS functionality via RAAS INHIBIT and FLAP INHIBIT switches in the cockpit.
Dynamic TOO FAST alerts based on target speed
TOO FAST alerts dynamically adjust based on your aircraft’s approach speed, providing precise feedback.

FAQ

Activation / Serial

Is an active internet connection required?
An internet connection is needed to activate the product on the first launch.

General

Do I have to launch vRAAS manually each time I want to fly?
The vRAAS process needs to be running for RAAS to function, but you can enable the auto-start option in the General Settings tab. Additionally, you can select options for Minimize to tray, Start minimized, and Auto-close so you won’t need to interact with the vRAAS window at all.
Does vRAAS reduce FPS?
We haven’t observed any noticeable impact on FPS.
Do I need Internet for vRAAS to work?
vRAAS automatically downloads aircraft-specific details at each launch. Although vRAAS generally functions well without an internet connection, some convenience features do require it.
Can I disable the self-test on startup?
Yes, go to General Settings and disable Self-Test on startup.
How can I change the unit of measurement to feet?
Go to Main Window > RAAS Features > ALL AIRCRAFT > Units and select your preferred unit.

Display

How can I disable the RAAS Display for certain displays?
Navigate to Main Window > RAAS Features > CURRENT AIRCRAFT > Display Setup. Check or uncheck the desired display, and you can also adjust the text position and size here.
I don’t see any text on my PFD/ND.
If you have just installed vRAAS, restart your Simulator.
_Ensure the community-folder plugin is installed (it should install automatically). Also, verify if your aircraft is on the supported list above. If not, go to Main Window > RAAS Features > CURRENT AIRCRAFT > Display Setup to position the text yourself or reach out on our Discord for assistance.
The real aircraft only shows RAAS text when TERR is selected on the ND. Can you add this to vRAAS?
vRAAS supports this, but many aircraft don’t provide the required data to detect if TERR is selected. If you know of a way to detect it, please share on Discord!
I get the self-test alert even when the aircraft is cold-and-dark.
vRAAS ties the self-test to the aircraft power state, but some aircraft don’t expose the required variables — in those cases the timing may be slightly off. You can also disable the self-test on the General Settings page.
