vRAAS² RAAS for Microsoft Flight Simulator 2024
Spoken runway awareness and advisory callouts for every aircraft: runway entry and approach alerts, takeoff and landing distance remaining, unstable approach warnings and runway overrun prevention, configured from an EFB app.
Requires Microsoft Flight Simulator 2024
Airliner runway callouts, in every aircraft
vRAAS² adds the runway awareness and advisory callouts of a modern airliner to every aircraft in Microsoft Flight Simulator 2024: airliners, GA, and anything in between. It runs as an in-sim module: no external program, no companion app on the desktop, nothing to alt-tab to.
What is RAAS?
RAAS, the Runway Awareness and Advisory System, is a Honeywell function of the Enhanced Ground Proximity Warning System (EGPWS) found in many modern airliners. It gives the crew spoken advisories about where the aircraft is relative to runways, to prevent runway incursions, taxiway takeoffs and landings, and runway overruns. vRAAS² brings that RAAS logic to MSFS, alongside Airbus and Boeing style Runway Overrun Prevention. Read more about RAAS.
Taxi towards a runway and it tells you which one you are approaching. Line up and it confirms the runway and the distance available. Roll out and it counts the remaining distance down. On approach it calls the runway you are lined up with, warns you when the approach is not stable, and if the landing is going long it escalates to overrun prevention advisories: max braking, reverse, or go-around.
Everything is configured from a vRAAS² app inside the EFB, in the cockpit, while you fly. Settings apply globally, per aircraft type, or per individual registration, so a heavy jet and a Cub can each have their own thresholds without touching the other.

What vRAAS² does
Runway awareness
Approaching-runway and on-runway callouts while taxiing, with runway designator, plus taxiway-takeoff and short-runway warnings.
Takeoff and landing distance
Distance remaining callouts in feet or meters, distance available on lineup.
Approach advisories
Approaching-runway in the air, unstable approach, too high, too fast.
Runway Overrun Prevention (ROP)
Continuous landing distance assessment with escalating advisories (max braking, set/keep max reverse, go-around), following Airbus and Boeing style logic.
Altimeter monitoring
Transition altitude and altimeter setting reminders.
In-cockpit configuration
An EFB app for every setting, with global / per-type / per-registration override scopes and a one-tap revert to the inherited value.
Aircraft profiles
Vendor profiles are bundled and refreshed from the cloud, so common aircraft work correctly out of the box.
Startup self-test
A spoken test on power-up (and a TEST button in the EFB) so you know the system is alive before you need it.
Voices
Multiple callout voices to choose from.
What pilots say about vRAAS
A selection of customer reviews from the Contrail Shop, quoted unedited. These reviews were written for vRAAS 1.x, the predecessor of vRAAS². vRAAS² speaks the same callouts and keeps the same core features, now running inside the simulator.
I love vRAAS and honestly can't do a flight without anymore, adds alot to the realism i want in my flights and it has 0 impact on performance. Can't be more satisfied!
Chris Exactly how a flightsim addon should work - totally automated in the background, working with every airplane without needing to setup anything.
Raphael I like the fact that there is no impact on FPS. Setup and configuration is very intuitive, which is very welcomed. The announcements are very clear and timed very well. I like vRAAS. It is now part of my system on every flight and on every aircraft that I fly.
Jay I thoroughly enjoy the immersion provided by vRAAS. Good pricing, excellent features and customization and unbeatable support. Highly recommended.
A Must Have Add-On If it's your first time launching the app, you can leave it be on default settings and run a few flights. If you want to spend 2-3 minutes fine tweaking to your liking, it is straightforward. It does not impact your PC performance or at least from what I notice. It also launches automatically with the sim.
M. Absolute awesome addition to MSFS. It just works, and is easy to configure.

Reviews and ratings are collected by the Contrail Shop. Only customers who own the product can rate or review it there, in the Contrail app. LAND3 Simulations does not check reviews beyond that and chose the quotes above from the reviews on Contrail.
Available callouts
Every callout can be customised or switched off from the EFB app. Advisories and cautions play at different volumes, just like the real system. Distances are spoken in meters or feet.
