ATIS not understandable

Postby NicoBee » Wed Jan 20, 2016 10:44 pm

Dear pilots,

I am new to FlightGear and I have a big problem understanding ATIS messages. I think that there is something wrong with my configuration but I did not found any help searching the net.

I recorded the ATIS message as it is playbacked at KSFO. You can find it here: https://www.dropbox.com/s/hhfc6cmy81g31c2/FlightGear_ATIS_SanFran.mp3?dl=0

Is there anybody who had got the same problem and who can give me a solution?

My system specs:
- Ubuntu 14.04 LTS (64bit)
- FlightGear 3.4.0 (startet with Flight Gear Launch Control / FlightGear Wizard)
- Intel Core i5-4570
- OnBoard Intel Graphics and OnBoard sound

Thank you very much in advance!

Nico.

Yeah, that sounds like FG's automated ATIS system. Lovely, ain't it?
You get used to it. Just put it on a loop and listen to it 50 times, it'll come to you. Otherwise, just look up the METAR data online.

Hello Pinto,

am I wrong or does the voice overlay or overtake itself? That is the reason why I was so sure, that my system is misconfigured ...

Kind regards, Nico.

By “online”, do you mean on a web site? Why not use Environment -> Weather? This shows the METAR string right in FG...

Different methods, same results.
I usually have the mpmap open in the background, so I pull up METAR data through that when I need it.

I don't know if this is the case for all platforms (I suspect it is), but in the same directory as your fgfs executable, there should be an executable called "metar".

This can be run from a command prompt, or you could create some sort of shortcut, depending on your platform. Here is an example of running this on Linux:

Code: Select all
$ metar EGLL
METAR Report      (automatically generated)
============
Airport-Id:      EGLL
Report time:      2016/1/22 8:50 UTC
Visibility:      >=10 km               >=6.2 US-miles
Wind:         from the SSE (160°) at 22.2 km/h      12 kt = 13.8 mph = 6.2 m/s
Temperature:      6°C               42.8°F
Dewpoint:      5°C               41°F
Rel. Humidity:      93%
Pressure:      1015 hPa            29.97 in. Hg
Weather:      light rain
Sky condition:      sky overcast at 800 ft         240 m

This is useful if the ATIS is unintelligible, or if an ATIS frequency is not defined for a given airport but it has a weather station in real life. Note that it gives the METAR for a given station; using Environment-Weather gives the weather at your location, which could be different from the weather at your destination airport.

Here is the inbuilt help text:

Code: Select all
$ metar --help
Usage: metar [-v] [-e elevation] [-r|-c] <list of ICAO airport ids or METAR strings>
       metar -h

       -h|--help            show this help
       -v|--verbose         verbose output
       -r|--report          print report (default)
       -c|--command-line    print command line
       -e E|--elevation E   set airport elevation to E meters
                            (added to cloud bases in command line mode)
Environment:
       http_proxy           set proxy in the form "http://host:port/"

Examples:
       $ metar ksfo koak
       $ metar -c ksfo -r ksfo
       $ metar "LOWL 161500Z 19004KT 160V240 9999 FEW035 SCT300 29/23 Q1006 NOSIG"
       $ fgfs  `metar -e 183 -c loww`
       $ http_proxy=http://localhost:3128/ metar ksfo

That's a good point!

Is this generated with TTS on the fly or made with prerecorded chunks?

It's generated on the fly with the FLite engine.
