It seems like genapts adds threshold markings (e.g. pa_threshold.rgb) to runways, which according apt.dat should have only visual markings. According to FAA AC 150/5340-1H (which is mentioned in rwy_visual.cxx), visual markings do not include threshold markings. According to that same sourcefile, you are the author of these functions. Did I miss something about that AC or is there a specific reason why threshold markings are included nevertheless in gen_visual_rwy? It's been a long time but I believe the original intent of the code is that precision and non-precision runways should have threshold markings, while visual runways should not have them. By my best recollection, this is how the code was designed and by my reading of the code, that is the way it still works. Do you have an example airport where this is broken?

Would that be 14ft in length (from 14/length)? That is only the thick painted line marking the leading edge of the runway I believe. The actual large threshold marking bars would be omitted. I haven't checked this on any specific airport, but I looked into the code due to Martin's question (top of this thread) about the markings included in the Visual marking type. Looking at Martin's question, based on what his runway includes, I would have said use non-precision markings. But then later he says that non-precision marking are not appropriate? Perhaps he could elaborate on that last point a bit? I should take a step back here and point out that the runway marking scheme is not designed to be able to handle every possible combination of marks that people might paint on their runways. There are FAA standards for the USA, and it appears that much of the world does something similar, especially for larger airports, but for other smaller airports, who knows? Some real person has to go out and paint the lines and they might not follow the FAA AC exactly as it is written. What we have is a comprimise ... a way to represent a huge proportion of the worlds runway markings using a relatively small number of embedded textures (rather than struggling with polygon overlays.)

[Flightgear-devel] Yet more aerodrome taxiways/aprons questions
Hello again, Almost ready to submit my first set of taxiways to FG/XPlane but first a few more questions. 1. Which version of TaxiDraw should I be using? I've been working with a CVS version from last week. 2. Should I submit apt.dat format 810? 3. Runway markings: The runway in question has edge, centreline and threshold (one of which is displaced) markings, plus some arrows pointing to the displaced threshold. Non-precision markings are not appropriate, will visual markings have everything I need? Martin. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

Hi Martin! Martin Fenelon wrote: 1. Which version of TaxiDraw should I be using? I've been working with a CVS version from last week. The CVS version should be pretty stable and generates v810. 2. Should I submit apt.dat format 810? AFAIK, TerraGear can handle 810. 3. Runway markings: The runway in question has edge, centreline and threshold (one of which is displaced) markings, plus some arrows pointing to the displaced threshold. Non-precision markings are not appropriate, will visual markings have everything I need? Visual markings should normally consist of the runway number, edge and centreline markings. Displaced threshold is marked using arrows. I have just looked at the genapts sourcecode, which generates additional threshold markings (see Texture/Runway/pa_threshold.rgb texture). However, from a principal point of view using Visual Markings in TaxiDraw would probably be correct. Curt, did I miss anything, or why are the threshold markings included in visual markings for genapts?
