This is what I see:Navigraph SID : SID WAL2V RNW 09 FIX OVERFLY DME01 AT OR ABOVE 580 HDG 322 INTERCEPT RADIAL 277 TO FIX WAL FIX WAL AT OR BELOW 4000 AT OR ABOVE 2500Edited:RW9 is on the 090 (radial) side of VOR WAL ... Looks like PMDG magenta line is not on SID HDG 322.I have not flown it to confirm which way PMGD actually turns but the intercept heading is 322 in Navigraph.So, it looks like PMDG is trying to use INT C HDG as a radial.322 - 180 = 142142 - 90 (rwy hdg) = 52 shortest turn direction/distange (arc).

Im not quite following your maths there I must be having a dim day Why did you subtract 180 from 322? Wouldnt that be the equivalent of the a/c believing it was actually taking off from RW27? Does that mean PMDG is calculating an erroneous shortest turn direction on correct navdata and if so how can that be corrected?Kevin

I also use Aivlasoft EFB, but since SP1B you cannot load a co route into the NGX containing SID/STARS. These have to be manually entered into the NGX FMC manually.I produce a flight plan using whatever flight planner through EFB "excuding any SIDS STARS. I then save that flight plan in .rte format to my appropriate PMDG folder. After doing this i modify this flight plan in EFB to add the SID and if desired ahead of time, you can add the Star you want. Then i save this modified FP in .pln to my FSX folder.iI then fire up my NGX and load the .rte CO route file into the FMC and select my SID and if desired, STAR and then finally open up my route in the EFB display and edit if necessary, any part of the plan that differs from the EFB flight plan so that all are the same.Works for me and then NGX and your ATC (RC4/VOXATC etc.) and EFB are on the same page.Regards,

Post a screenshot of what you see (the OP's SID ref.) .. is yours correct in PMDG?

"Why did you subtract 180 from 322" ?To convert to a radial to intercept .. just for an example.See another of my post/screenshot above where I changed the SID..

Hmm, this may not make sense at all but.... looking at my original screen shot of the EFB SID track in the NGX the track appears to turn left approx 170/175 degrees towards an approx heading of 280, whereupon it intercepts the 277 WAL radial, the a/c then turning right slightly to follow it. The a/c will never intercept the 277 radial once turned to 322 because it will be too far north to do so, which necessitates the near 180 turn back to intercept the correct radial.The printed SID chart I linked to earlier shows the departure track turning left then merging straight onto the radial. Clearly in that case the a/c will be able to turn through 322 degrees to intercept the radial and the logic allows the navigraph data to conform to that.Is the NGX just being too clever by half, realising that its speed and turn radius will not allow it to make the left turn in sufficient time to intercept the 277 radial from a course of 322 and so therefore it decides to turn right where it can intercept the 277 radial from a course of 322? Of course, this track is still following the navigraph data in strict terms, just not as it was intended to do so? :oOr am I just getting far too confused!?!kevin

Kevin,Ok, I found a SID plate which shows correct HDG and radials (which are "from" a navaid) to fly.Here: http://www.nats-uk.ead-it.com/public/index.php%3Foption=com_content&task=blogcategory&id=91&Itemid=140.htmlThis is what I requested (wanted to see) in my previous post.It contains the correct narrative.Give it a try.

Kevin,Here, as a test today, I changed the Navigraph SID to use the WAL R-097 per the narrative in the SID.SID WAL2V RNW 09 FIX OVERFLY LPLNB AT OR ABOVE 580 HDG 322 INTERCEPT RADIAL 97 TO FIX WAL FIX WAL AT OR BELOW 4000 AT OR ABOVE 2500
