Hello Happy New Year Everyone,On the 744X "British Airways' lively, there is already a call-sign Speedbird, but the MSFSX ATC does not call it. The ATC for some reason does not call "speedbird XXX for the 744X. However, it calls it for the ai British Airways Airliners. I'm using the same "Airline.CFG" as I used for the FS9 version which was okay then. Am I doing something wrong?On unrelated issue, what does "Split IRS Program" means (FMC MSG)? This happened on a flight along the polar lines (UAL897-KIAD-ZBAA...flightaware.com....real world flight plan in real time.Is this equivalent to "IRS NAV ONLY' on the 767? Flight went on with no glitches though. ThnxGus

Gus,Locate the config file entry for your BA livery and check to see if the atc_Airline entry reads Speed Bird with a space between Speed and Bird.

>Gus,>Locate the config file entry for your BA livery and check to>see if the atc_Airline entry reads Speed Bird with a space>between Speed and Bird.Pete,I checked and it had "SPEEDBIRD". All in caps and I changed it to match my airline.cfg "Speedbird", but that did not help as ATC continues to call it without the call sign. Do you have the repaint (this is from PMDG website)? and does it do the same as mine? If yours is any different, can you post your CFG for comparison? Anyway, any idea about the FMC MSG? ThnxGus

hi Gus,change this...SPEEDBIRD to this...Speed BirdATC will recognize the call sign now. happy flyin, Tim Wheeler

>hi Gus,>>change this...SPEEDBIRD to this...Speed Bird>>ATC will recognize the call sign now.>>>> happy flyin, Tim WheelerHi Tim,I just tried that and still didn't help. ThnxGus

hi again Gus,sorry to hear that. that's rather strange. that worked with FS9 default ATC. MS must have changed something in FSX. sorry, but i don't have any other suggestions other than trying Radar Contact4 for FSX. it's a payware addon. if your interested you can find out more about it here... www.jdtllc.com and here...http://www.fsstation.com/reviews/radarcontact.html happy flyin, Tim Wheeler

S-O-L-V-E-DHello,For those interested in this discussing and was halving the same problem as mine (Not having FSX to recognize British Airway call-sign "speedbird')I have found the solution to it. The PMDG FSX version does not see the "Airlines CFG" speedbird (lower cases). I tried LVD767 and saw that on the detail section in FSX when you select your aircraft, their version had "SPEED BIRD" and FSX ATC called "Speed Bird". I then copied this (SPEED BIRD)to PMDG British Airways, but then inside FSX, it only showed as "speedbird" and still ATC did not recognize the call sign. I then right away had an idea to add 'SPEED BIRD" to the Airline CFG and behold it works. PMDG probably needs to look into this, but was anybody having the same problem? Thnx Gus
