RAAS Professional By FS2Crew - Review

KLAX airport diagram showing the maze that hundreds of aircraft each day must safely navigate.  Given the complexity of many airports, it's amazing there are not more runway incursions

Runway incursions are a leading cause of aviation fatalities and account for approximately $1 billion annually in aircraft damages. To help prevent such losses, close calls and collisions, the industry requested a safety system that would help maintain situational awareness during taxiing and preparing for takeoff and landing. 

Honeywell stepped in to fill the gap by developing an easy-to-install heads-up advisory system with aural alerts (call-outs) to increase flight crew situational awareness during ground and air operations relative to the runway. 

This system was then further improved upon, with the collaboration of Emirates.

I previously used a shareware version of RAAS developed by PlaneMan in South Korea.  This small FS add-on worked well, however, recently it stopped working on my system for an unknown reason.  I wrote a review on FsRAAS by Planeman in 2011.  Searching for a replacement, I came across RAAS Professional developed by FS2 Crew.  

What is RAAS

RAAS is an acronym for Runways Awareness And Advisory System (RAAS).  RAAS was developed by Honeywell Aerospace as a simple to install but effective software addition to the Honeywell Enhanced Ground Proximity Warning System (EGPWS).  Although the base-line RAAS is still in operation, Honeywell has improved the software by integrating additional aural advisory call-outs; in particular, relating to stabilised approaches.  SmartRunway and SmartLanding are the next generation of RAAS.

RAAS Professional replicates the complete aural Honeywell suite (RAAS, SmartRunway and SmartLanding), however, does not simulate the visual advisory displays.

Simulator Platforms

RAAS will operate on FS9, FSX and P3D V3 simulation platforms in 32 Bit.  A 64 Bit version of the program caters towards those using P3D V4. if using MSFS-2020 another version of RAAS is required called RAAS Professional by FS2Crew. The RAAS Professional software is more or less identical to the RAAS software but installation is slightly different.

Installation

Installation is via an installer and is straightforward.  The software installs a .ddl file which is loaded automatically when you begin a new simulation flight.  Once installed, a tab (RAAS Professional) will be added to the menu bar in flight simulator; this is where the user interface is opened to configure the program.  I did not experience any issues installing this program.

RAAS uses Simconnect to connect to flight simulator and does not require the use of FSUPIC.

Be aware that problems can occur when attempting to connect any add-on software that uses Simconnect (as opposed to FSUPIC).  If a problem occurs, the easiest way to rectify it is to re-install the Simconnect module of flight Simulator.

Initial Configuration (Managing the Runway Database)

The most important task to complete prior to configuring RAAS is to download a small standalone program called MakeRunways.  This software has been developed by Peter Dowson and is available gratis from his website.  The MakeRunways utility should be placed in your main flight simulator folder where the Scenery.cfg file is located.    

When run, MakeRunways interrogates the scenery folder and generates several database files that include, amongst other things, the runways found in flight simulator.  The generated files are automatically saved to your main flight simulator folder, for programs such as RAAS, to access and read. 

Whenever you install new scenery you must run the MakeRunways utility to ensure that the database is synchronized and up-to-date, otherwise RAAS will not work with the new add-on airport scenery.

Of importance, is that the 64 Bit version of RAAS requires an additional program to be installed.  The reason for this, is that vP3D V4 use a dedicated addons folder.  The Add-on organizer enables the add-on folder in P3D V4 to be interrogated by the MakeRunways program. 

Important Point:

  • If using RAAS Professional for MSFS-2020 MakeRunways is not required.

The Lorby Prepar 3D Addon Organizer can be downloaded gratis at the developer’s website (see downloads section). 

The installation of these programs is very straightforward and instructions are provided in the supporting documentation.

Advanced Configuration

RAAS, like its real world counterpart, is highly configurable from the User Interface (UI) accessed from the Add-Ons menu bar in flight simulator.

The following aural call-outs (advisory) are available.

  • Approaching Runway (On Ground): advisory provides the flight crew with an awareness of when a runway is being approached.

  • Approaching Runway (In Air): advisory provides the flight crew with an awareness of which runway the aircraft is lined-up with during approach.

  • On Runway: advisory provides the flight crew with an awareness of which runway the aircraft is lined up with on the ground.

  • Runway End: advisory is used to improve crew awareness of the runway end during low visibility operations.

  • Taxiway Take-off: advisory alerts pilots to excessive taxi speeds or an inadvertent takeoff on a taxiway.

  • Insufficient Runway Length (On Ground): provides the crew of an awareness of which runway the aircraft is lined-up with and if the runway length available is less than the defined minimum takeoff length.

  • Extended Holding on Runway: alerts the crew of an extended holding period on the runway.

  • Approaching Short Runway (In Air): offers an advisory of which runway the aircraft is lined-up with and if the runway length available is sufficient as defined in the Runways section.

  • Taxiway Landing: alerts the crew if they are not lined up with a runway at low altitudes.

  • Takeoff Flap Monitor: alerts the crew if the aircraft's flaps are not in the defined takeoff range.

  • Landing Distance Remaining: provides the flight crew with an awareness of the runway length remaining during roll-out.

  • Distance Remaining (Rejected Takeoff): provides the flight crew with an awareness of the runway length remaining during a rejected takeoff.

  • Landing Flap Monitor: advisory alerts the crew if the landing flaps are not set.

  • Excessive Approach Speed: is an alert if the aircraft speed become excessive compared to the final approach speed.

  • Excessive Approach Angle: is an alert if the aircraft's approach angle becomes too steep.

  • Altimeter Setting (Above Transition): alerts the crew if the altimeter is not set to standard after climbing above the transition altitude.

  • Altimeter Setting (Below Transition): provides the flight crew with an awareness of improper corrected altitude setting while below the transition altitude.

  • Long Landing: alerts the flight crew if the aircraft has not touched down within the defined Touchdown Zone Length.

  • Caution Enabled: adds the phrase ‘Caution’ to select aural calls.

Any of the aural call-outs can be turned on or off and several parameters are configurable from the UI.  Additionally, specific parameters can be changed depending upon aircraft type or airline policy, such as:

  • Aircraft type.

  • Runway takeoff and landing length, runway length and touchdown zone. Hold times (initial hold time and repeats).

  • Flaps configuration (takeoff, landing, upper and lower altitudes).

  • Approach speeds.

  • Transition altitudes.

  •  Extended hold times and frequency of the aural call-out.

If you fly different aircraft, any number of user profiles can be created.  The profiles are associated with the aircraft type selected in flight simulator.

rAAS Professional User Interface (UI)

Comparison - RAAS Professional to the  Honeywell System

RAAS Professional by Fs2Crew replicates the real Honeywell system surprisingly well.  The aural call-outs are identical and the female voice sounds very similar to the voice used by Honeywell - which provide either a female or male voice.  If you’re keen to compare RAAS to the Honeywell system I recommend you visit the Honeywell website, search RAAS and watch the videos.

Turning RAAS On and Off (RAAS Master Switch)

RAAS can be turned on and off ‘on the fly’ from the User Interface (UI), or by assigned a hot-key (key event API) in flight simulator.  By default the on/off function has been assigned to the water rudder (R) function (from within the flight simulator control panel).  It is also possible to assign this functionality to a switch/toggle.

Sound Cards and System Test

RAAS has been designed to be used within multiple speaker environments, and changing the speaker preference is made directly in the User Interface (UI).  With a little tinkering you should be able to dedicate the RAAS aural call-outs to a separate speaker while maintaining engine noise and Air Traffic Control to other speakers and a headset.  A master volume control tab enables the sound levels to be adjusted (if the speaker does not have volume control knob).

The UI has a System Test to determine correct configuration and connection (audio test) and an error log.  The error log can be used during troubleshooting (if necessary).  

Voice Sets and Memory Use

Currently RAAS only supports English in a female voice.  I believe that additional foreign language voice sets may be released in due course.

When RAAS is running, there is no discernible effect on the computer or flight simulator.

Support

A detailed and easy to read manual is supplied with the program.  The manual, in addition to providing detailed installation instructions, also has a very good troubleshooting section in the unlikely event that you have problems during the installation process.

RAAS supports a dedicated support forum and the developer replies to questions when asked.  

Program Shortfalls

At the moment it is not possible to install RAAS on a client computer and run the program across a network.  Although RAAS does not use a lot of computer resources, some users may wish to display the UI (when required) on a client screen in association with the Instructor Station.

Another shortfall is the inconsistent operation of the key event API (that enables you to connect a switch/toggle to the on/off function / RAAS Master Switch).  Sometimes it works and at other times it does not work correctly.

Final Call

If you seek realism, RAAS is a worthwhile addition to flight simulator.   When configured to an appropriate aircraft, the aural call-outs are timely and helpful to situational awareness.  Two features I particularly like are the ability of RAAS to remind you to set the appropriate flaps detente prior to takeoff, and the aural call-out that is generated which identifies the runway you are aligned with during final approach.

I must admit there was one occurrence when I was conducting a VOR approach to a parallel runway in limited visibility.  The aural call-out stated I was aligned to runway 24 Left when I was supposed to landing on runway 24 Right!  But isn’t this the reason RAAS was designed – to stop incursions and provide situation awareness to flight crews.

Runway Awareness & Advisory System (RAAS) - FS Add On

A runway incursion is an incident where an unauthorized aircraft, vehicle or person is on a runway. This adversely affects runway safety, as it creates the risk that an airplane taking off or landing will collide with the object.  Runways incursions are not uncommon.  One carrier, Alaska Airlines has introduced an additional warning system in their flight decks to counter against this potential problem.  The system is called RAAS or Runway Awareness and Advisory System.

The Runway Awareness and Advisory System developed by Honeywell in 2003, provides pilots with audible alerts when they approach and enter taxiways and runways. The system confirms runway identifications to help ensure pilots are on the correct runway with enough distance to complete takeoff, and provides an audible warning if a pilot inadvertently accelerates for takeoff while on a taxiway. 

RAAS is not compulsory in the real world, but is an option that is purchased by an airline.   The use of RAAS is a nice addition to include in your flight deck.  Dongjin Shin, a software engineer has developed RAAS for us to use in flight simulator.  His program is called FsRAAS Runway Advisory.

Software Installation and Make Runways

The program is a stand-alone program, meaning it does not need to be installed into flight simulator; it can be run from anywhere on your computer, however, I have been 'informed' the recommended place for installation of the software is in the same folder that FSUPIC is installed (FS10 root directory/modules).

Once the program has been installed, it is necessary to synchronise the runway data in your scenery file with FsRAAS.  To not do this will cause erroneous call-outs.  To synchronise the runway .bdl file you run MakeRunways 4.692 developed by Peter Dowson.  This software is stand-alone and can be downloaded for free (MakeRunways).  Follow the instructions carefully and once the software has been run, copy the generated r4.csv file found in the modules folder to the same folder that you have FsRAAS installed.  Copying this file will ensure that FsRAAS is synchronised with the airports in your scenery file.   It's important to remember that if you update your scenery, MakeRunways will need to run again and the file copied across to FsRAAS folder.

FsRAAS can be started before or after FSX; I prefer to start the program after FSX has been configured for flight.  I have a shortcut to FsRAAS on my desktop menu and after FSX is running I click the shortcut and FsRAAS immediately starts and minimises. At the moment, FsRAAS cannot be run from client computers as it does not support WideFS.  However, the computer workload of running this very small add on is not noticeable on high-end computers.  The program does require FSUPIC for correct operation.

Evaluation

My initial evaluation of FsRAAS has been excellent and I’ve incorporated this program into my flight deck.  The program will provide, at the minimum, the following audible call-outs;

  • Approaching/crossing taxiway

  • Approaching/crossing runway

  • Flaps not set call out (flaps flaps flaps)

  • Lined up on runway (ie: runway 34R call-out)

  • Runway distance remaining after take off roll (eg: 2000 feet remaining call-out)

  • Runway distance remaining after landing and roll out

  • Approaching runway on final approach (approaching 34R call-out)

The software's .ini file can be easily altered to reflect certain changes in the various call outs such as distance to a runways, approach speed, etc.  The .ini file is found in the FsRAAS folder.

My only vague criticism (if pushed) is that the call-outs are slightly delayed when approaching a runway or taxiway.  The program is currently a free program and can be downloaded directly from Shin's blog site, or search the AVSIM library for FsRAAS11-1, or the latest release FsRAAS 2.

Update

on 2012-07-03 06:16 by FLAPS 2 APPROACH

A new version of FsRAAS has been released which rectifies some of the shortcomings in the original version and adds additional functionality.  It is called, not surprisingly FsRAAS V2.

Update

on 2018-03-23 11:53 by FLAPS 2 APPROACH

Recently, FsRAAS V2 stopped working on my client.  Despite considerable fault-finding I could not establish why this occurred.  Speaking with other enthusiasts, I discovered that I was not alone as others had the identical problem.  Therefore, I did further research to determine if another RAAS add on was available.

Note that FsRAAS V2 does not operate on the Prepar 3D simulator platform.

I purchased from FS2Crew FS2Crew Professional RAAS.  The Software replicates the original callouts produced by Honeywell (the developer of the RAAS system).
