viperxbr Posted November 12, 2014 Share Posted November 12, 2014 Gents, It's been a while! Hope all is going well with v2. Quick observation when flying VATSIM using vPilot. I've notice that the speeds seem to be quite a bit off using GS or IAS when viewing other online traffic. I've tested with a few pilots online and what they report to me for GS is a few hundred knots less than what I see in EFB using Ground Speed selection. When using IAS setting, their actual GS is a couple hundred knots higher than what I see. Just wondering if that is a known issue with vPilot or am I missing something? Thanks, Todd.

aivlasoft Posted November 12, 2014 Share Posted November 12, 2014 Hi Todd, there are two things to check: 1) DisplayUnit settings, tab "Charts", then tab "Traffic". There you will find an option named "Pilot client software ...". Try whether to tick that option helps. 2) DataServer, menu "Data", then "AI aircraft monitor". There you can see different speed values. Maybe you can see which one is the right one? Just let me know. Link to comment Share on other sites More sharing options...
viperxbr Posted November 13, 2014 Author Share Posted November 13, 2014 Hey Urs, I've tried what you suggested. I've noticed that it is actually much closer to the actual speed of others than originally stated. It seems both IAS and GS on EFB is averaging around 15-20kts more than what the other online pilots are doing. For example: DAL2022 was seeing a GS of 535 and on the EFB AC monitor was reading it as 553kts. Around the same difference for the IAS. So it must of been one of the patches of vPilot that may have reduced the speed differences... not sure. But it has been awhile since I really looked into it. Thanks, Todd.

aivlasoft Posted November 14, 2014 Share Posted November 14, 2014 Hi Todd, If I recall correct, then in the past we had similar issues with FSInn and Squawkbox. I'm not sure anymore but maybe these pilot clients are setting the "True airspeed" as speed value. Maybe that's now also with vPilot? Link to comment Share on other sites More sharing options...
viperxbr Posted November 14, 2014 Author Share Posted November 14, 2014 Hey Urs, I do remember, a while back, I posted an issue with a large GS variance between EFB and the latest IvAp (IVAO) client. Here are the previous posts: http://www.aivlasoft.com/support/viewtopic.php?f=5&t=1160&hilit=ground+speed http://www.aivlasoft.com/support/viewtopic.php?f=5&t=870&hilit=ground+speed I'll get back to you after doing some TAS comparisons. I never thought of obtaining those readings... ***Update: A couple of tests. Online AC #1: EFB reading= 422kts (EFB set to GS) Actually: GS 431kts TAS 447kts IAS 277kts Online AC #2: EFB = 439kts (EFB set to GS) Actual: GS 447kts IAS 292kts So far it doesn't look like it's even TAS on EFB. I'll ask for more tonight. Cheers, Todd Link to comment Share on other sites More sharing options...
aivlasoft Posted November 20, 2014 Share Posted November 20, 2014 Hi Todd, when comparing the speeds between different aircraft, don't forget the delay of the programs. EFB is reading what the Pilot Client Software is forwarding to FS, whereas VATSpy and similar programs read the "whazzup" data stream (IIRC). So in my opinion you most probably will not get a match between these two programs. Link to comment Share on other sites More sharing options...
