Runway Awareness and Advisory System (RAAS)

Recommended Posts

Browsing the iFly forum yesterday I was introduced to and fascinated by this relatively new technolgy.

 

Thanks to one erase the following link was provided:-

I commend all heavy simmers research this, download and run Dongjin Shin's brilliant program which, although free, is FAR more worthy than recently released payware.

 

Blue skies. :Just Kidding:

Yes, I confirm this is a great little utility. :good:

Adds realism and fun.

Gonna give this utility a look-see tonight. The demo video on youtube convinced me. I am for anything that adds more realism to my sim experience. Thanks for the link Appliance!

Too little too late. I already bought it. :Cry: It is still good, but knowing there is a free one out there is annoying. Thanks for the heads up anyway.

Amazing! Thanks for sharing.

BTW does anybody have list of airlines currently using RAAS on which aircraft types? I have seen videos of EK 777's and LH 744's where they had it installed. But I have no clue who else uses it on what part of the fleet...

Thanks nam1394! Do you know which aircraft are equipped with RAAS at those airlines? I heard that for example Lufthansa only has it on their B744's...

Fedex also have it installed on there MD11 freighters.

I really don't know details. But these the airlines that started installing it in some of their planes. Alaska for example started in 2008.

So far I came up with:

  • Lufthansa: B747
  • Alaska Airlines: B737
  • United: ?
  • Air France: A32X, A330
  • Emirates: B777
  • SWISS: ?
  • FedEx: MD-11, B727

I have to check some more Youtube videos. Since AF has it on their A32X and A330 fleet, they might as well have it on their A340's. Probably also their 777's and 747's. I guess there are many many more operators out there. Would be cool to get a list, so one can simulate the system close to reality in FS. I'll update the list here as I get more information.

It seems these are mostly for use in extreme ground low visibility where it is difficult to see path boundaries and intersections besides taxiing in unfamiliar airports. Now that at some airports transponders are kept hot on the ground for tower based ground control (forgot the term) is there any tie in with this device emulating a TCAS for the ground? In FS as well?

Actually, there is a video of Swiss A330 at KORD and it was following another plane and visibility was good.

The RAAS has nothing to do with a "ground TCAS". It is also not limited to low vis ops. As the name states the system intends to raise the "runway awareness" around airports these days. That means even in nice weather, just look at how many incidents there were in the past where pilots tried to take off or land on a taxiway or a wrong runway. I read a report that runway incursions could be reduced by 6-10%, if all aircraft operating at an airport would be equipped with RAAS.

 

Since the Honeywell-system works through the EPGWS interface, I doubt it is possible to couple it with the TCAS. Also I am not sure if your idea about the "hot" transponders on the ground would be enough for the TCAS to work on the ground. At least not without modifications to the software and probably also to the technology. I guess in FS you would go crazy anyway with a ground TCAS, considering the amount of AI traffic at some virtual airports :biggrin:

 

Thanks nam1394 for the Swiss A330-video. So we can add this one to the list too!

Integration with transponder responses I was referring to this:

 

http://en.wikipedia.org/wiki/ASDE-X

 

if aircraft TCAS displays would see other aircraft since as stated on airport diagrams is a callout notifying aircraft to keep transponders on during taxiing.

 

I would be nice to have it combined into an integrated display.

Can confirm that this is an excellent utility. I use it all the time now. I only wish it included taxiway naming and distance to taxiways per the real RAAS, But, it's freeware and excellent too. Thanks much to the author.

The only glitch is the lady sometimes ticks me off in surprising situations.

For instance I am peacefully taxing and suddenly she shouts 'On the taxiway! On the taxiway!'

Or recently I was overflying and airport (at flight level) and heard 'Approaching runway 35 left!' Big%20Grin.gif

Other than that, I love this addon too.
