Hello there. I am a new user of FSX and MYTRAFFIC. I am a past user of  FSLIVE for FS2004. I am using MyTraffic 5.4 PRO along with the MyTraffic Live subscription. I followed the instructions in the documentation. I am able to download the data (which as of 1042 pm pst 2/12/2012 it's 11801245) and have successfully created an ANFS.BGL. Unfortunately I am getting fights that are COMPLETELY out of date or in accurate.

Example:
I have united 1278 which is arriving into LAS, but the real world departure just happened. It's 9:03PM and the flight is about to land when per flightaware, the flight just took off from DEN and shouldn't be in Vegas for another 1 and a half. http://flightaware.c.../flight/UAL1278

I had a Southwest flight 1561 just depart LAS  to Ft Lauderdale at 9:05 PM but per flightaware it flew yesterday from DAL-STL. http://flightaware.c.../flight/SWA1561

DAL1073 is showing coming into LAS from CVG and yet per flightaware it is showing as going PDX-MSP and arrived two hours ago. http://flightaware.c.../flight/DAL1073

The only actual real flight that was close to being accurate was an American 1453 flight from KMIA that had 45 mins left. http://flightaware.c...0040Z/KMIA/KLAS

Why is the data so mix matched and inaccurate when it's downloading data that should be accurate?? I have my computer clock set to Pacific time, which is where I live so I don't think that is the issue. What can I do to make the flight schedules match up to the correct flights? I have tried it with traffic settings in FSX of 30 and 100 percent and it's still the same out of date jumbled data.

Appreciate all the work you have put in for us AI nuts. I look forward to hearing back.

David.

All MyTraffic Live can do is to interprete the latest data it gets from the AirNav server and transform them into schedules. Air Nav obtains the same data as flightaware ( which is the FAA ) plus their own radar box network that actually shows where the aircraft are in real life ( and not what the official flight plan submitted by the pilot before departure the FAA publishes ).

AirNav and Flightaware have different strategies to deal with the FAA raw data ( which are often just plain wrong, often very incomplete). I cannot comment on the quality of these data treatments, it looks to me that Flightaware tends more to use the marketing schedules as fallback if there is a data problem.
Also inside of AirNav the data from the Radar box network and the FAA differ a lot. The same flight # can show up in one data set to be parked at KLAS one moment and to be near New York 5 minutes later. That can be that the pilot has not changed the transmission code, or whatever. All this gets more complicated since more and more airlines use alphanumeric flight numbers internally to fly the scheduled numeric flight numbers, with no obvious mapping of the both.

So the situation that the two data sets show different information is frequent, and ths software as online real time software has only very little time to judge which of the two to use - AirNav always complains the software already takes too much CPU from their server. But to show both solutions doesn't help, complaints about double flights were frequent in early times of AirNav Live...

So I think the software tries to do the best thing that is possible. It cannot be free of bugs, has to make a lot of assumptions and adaptions ( FSX AI schedules have to always end at the airport they originate from, airlines rotate aircraft between bases,...) And don't trust Flightaware too much, they also can be wrong - and are completely incorrect on most airports since they only know of a tiny handful of airlines. MyTraffic X contains more than 4000 paints of airliners - less than 300 of them would ever be used by Flightaware data, AirNav at least uses about 1500.

Thanks for getting back to me. I recognize that we will never fully be able to experience 100% correctness unless we all go and start our commercial pilot careers. What you said makes sense. I guess it's just a bit of a downfall, by my own part to lookup and see if flight #'s correspond with flightaware, guess ignorance is bliss. I will continue using the product and see how it fairs. I remember seeing the thread back on Jan22 about airnav servers crashing and needing to rebuild their database.

Just to verify I have the process down- Schedules and choose my traffic live then go to download and download the ANFS.bgl? Also, I choose to disable MyTraffic MIL, global, and commercial. I seem to now have only flights that are using "live" models. Is that OK or do I need to have the commercial and global BGL's in the scenery folder along with ANFS.bgl? Thanks again!

[Burkhard]

That depends what you want. If you only want the life flights, which means:
1) Flights that have a type existing in MyTraffic, AND
2) Flights were the airline submits the data, AND
3) These data are correct or make a bit of sense at least, AND
4) These data are processed correctly by AIR NAV, AND
5) These data are processed correctly by MyTraffic Life, AND
6) These flights pass the checks by trafficdatabasebuilder to be likely, AND
7) FSX decides to show these flights, AND
The data of these flights have been confirmed by the airline or a tracking station over the last 8 hours at least once,

then only use ANFS.bgl and not another one, and set the traffic density to 25%.

I would want much more, because this requirement does not show more than 20% world wide of what happens out there in reality, but that is your choice.

I am only focusing on traffic into and out of USA. Thank you for the above clarification. If focusing on only flights in the US ( I have an FSLive 3 US edition account which is what I am using to download) will having the sliders to 100% and using only the ANFS.bgl give me 100% availability of flights based on the list you gave me?

[Burkhard]

Yes, unless I forgot another constraint. If you have set the sliders at 100%, you will see all flights that have been seen in the data once over the last 48 hours. If you go to 50%, you will see all flights that have been seen in the data once over the last 12 hours. If you go to 25%, you will see all flights that have been seen in the data once over the last 3 hours. If you go to 10%, you will see all flights that have been seen in the data once over the last 30 minutes - then you will have a very high rate of correct timings, but the lowest level of traffic.

Thank you for answering how the traffic setting works. Makes things much clearer in understanding.

If having the traffic setting to 25% to view flights within the past 3 hours does that mean it will only display flights that have been active in the past 3 hours from the time of downloading the data? If I download data at 12:00pm will the data be accurate from 9:00am-12:00pm or 12:00pm-3:00pm? Does the data downloaded hold regards for scheduled flights or does it only display  flights that have already occurred?

[Burkhard]

This three hours mean that either a Radar system has got contact to the aircraft the last three hours, or the flight plan has been submitted or changed not longer than 3 hours ago. The data contain flights that have landed, that are active or are planned, for those planned it only can use the plan and does not know the future.
