MakeRwys Closed Runways / Short Runways


RJP

Recommended Posts

Hi,

I've recently created a tool in Excel, using a table of ICAO ID, City, Region, Lat / Lon to produce a map of airports, coloured differently for those I've visited and those I haven't yet visited. The last logged airfield is identified along with the distance from that to each other airfield.

I decided to add some functionality which would require other data such as runway surface, runway length (& ideally runway width, ILS provision etc).  In trying to find that data I came across MakeRwys which seems to provide just what I need.

I am having an issue though......... listing closed runways. Some airports in FSX in The Bahamas (just the area I'm looking at initially, there may be others) have only closed runways.  An example being MYZ2 (Cape Eleuthera).  I'd like to include closed runways in what I'm doing, the 'ClosedLanding' and 'ClosedTakeoff' fields in Runways.xml suggests that MakeRwys has the ability to list where either is 'TRUE'.  Have a missed a command line switch to include them? Those fields are always only populated with 'FALSE'.

I understand the need for the minimum runway length field, however, on the offchance that closed runways were listed with 0 length I set the switch to />0 (i.e. "makerwys />0").  The shortest runway in the results is 1503, should that be the case? (default FSX scenery library)

Thanks and many thanks in advance for any advice

Actually, I've just found another -- VHHX.

I think the reason is that both of those have no runway "start" positions -- i.e. no entries in FS's runway list in the World - Go to airport menu. Certainly those with runway start positions (defined thresholds) do get correct CL and CT labels in the runways.csv file where appropriate, and TRUE in the fields in the XML.

Those airports with no threshold positions listed are actually excluded from all of the files except the XML one, where I think they are only there by omission on my part -- I forgot to exclude them! The files are supposed to list only usable airports, ones where the programs which use them can actually direct aircraft to and from (mainly ATC programs).

Evidently, for the ones included (in error I think) in the XML file, I bypassed the check on the open / close flagging. I could look at that and maybe fix it. It won't be for a few days though.

No, closed runways won't have zero length, but a lot of add-on sceneries use what are called "ghost" runways, which are not displayed and have short lengths and often narrow widths. One I saw recently was 9 feet x 4 feet! I'm not sure why they do this -- something to do with dealing with different AI traffic patterns I think.

I'm afraid I've no idea what the shortest runway length is in the default FS scenery. Why don't you try making one shorter (using an AFD program like Airport Design Editor) and check? In a few days, when I can get to looking at the code for your first point above, I can double check that I don't impose a "minimum minimum", It's unlikely, though, or it would (should) be mentioned. If it does it would be to eliminate those ghosts.

Hi Pete,

Many thanks for such a quick reply.

Might it be possible to have a switch to select whether or not closed runways are included?

According to a bit of googling it's TNCS (Saba, Netherlands Antilles) with 1,300 feet (evidently they're excluding the microlight fields). TNCS doesn't appear for me.....

Don't be mad at me but....... If I don't use the Water switches (makerwys />0) then I get 2 runways included (well both directions of 1) at EDCY with a surface type of Water (the other water runways at EDCY aren't listed).  If I include the Water switch (makerwys />0 /Water) then I get the same results.  If I use makerwys />0 /WaterOnly I get the same (lots of runways, only 2 water). If I use makerwys /Water then I get plenty of water runways included (including the other ones at EDCY). MakeRwys /WaterOnly includes a gravel runway at IN53. For EDCY only 2 of the 4 water runways are listed. MakeRwys />5000 gives plenty of runways, including many under 5000'.

Hope that doesn't cause grief? Thought it might be useful to list what I was / wasn't seeing.

Best regards & again, many thanks

I -think- what's written to the XML might be the issue....... using "MakeRwys />0 /Water", in the text file for (eg) AK02 I get;

whilst in the XML I get;

For the first sample airport I was looking at (MYZ2, Cape Eleuthera) the txt IDs a closed runway (without of course the start & end points):

I've made a note of all of your points and will check them when I get a moment. I'm afraid that might not be till I get back from my next travels, 20th September. I have a few days before going but will be pretty busy. Will post again if I find anything -- if you've not heard by, say, Friday 23rd, remind me, please.

Hi Pete,

I managed to manipulate the info in runways.txt to create a spreadsheet with a listing of all airports, all runways (inc length / width, surface & including closed) & all comms data.

I understand that the files that MakeRwys creates are intended for use in the like of ATC utilities so my file may be of no use but if it might be of benefit to someone please let me know & I'd be very happy to send it.

Best regards

Richard

Hi Pete,

No probs! I've been a bit tied up for a few days but once I have some time I'll tidy the file up and post it.

Hi Pete,

Just cleaned up the file for upload...... Unfortunately though it's still 11.5mb so way over the attachment limit size.  Is there any other way to upload / share it?

Some airports in FSX in The Bahamas (just the area I'm looking at initially, there may be others) have only closed runways.  An example being MYZ2 (Cape Eleuthera).  I'd like to include closed runways in what I'm doing, the 'ClosedLanding' and 'ClosedTakeoff' fields in Runways.xml suggests that MakeRwys has the ability to list where either is 'TRUE'.

I'm just starting to look at these things.

Taking this first question, I am puzzled. As far as I can see, those runways without "Start Positions" designated (i.e. no thresholds for take off or landing positively identified) are simply not included at all in the Runways.XML. For instance, here is the entry for the default MYZ2:

<ICAO id="MYZ2">
	<ICAOName>Cape Eleuthera</ICAOName>
	<Country>Bahamas, The</Country>
	<City>Cape Eleuthera</City>
	<File>Scenery\0302\scenery\APX27230.bgl</File>
	<SceneryName>0302 Base</SceneryName>
	<Longitude>-76.300003</Longitude>
	<Latitude>24.783333</Latitude>
	<Altitude>9</Altitude>
	<MagVar>-3.000</MagVar>
</ICAO>

The same applies to the VHHX I thought I'd identified as another example, and also, in fact, to your AK02 example.

I'm not really willing to make such drastic changes to the program in order to add unusable runways to the XML file. It would mean whole new structures internally, a more sorting routines. The current Runway data, included in all files, is dependent upon their having identifying thresholds for the majority of programs which use them -- for navigational information, mostly.

I know some folks who wanted more from the files instead took to reading the log file (Runways.txt) instead, though if you do that you should search for airports from the end back because the later ones usually override the earlier one (depending on the "deletion" entries).

BTW I note that in one of my previous replies I said it looked like I hadn't omitted such runways in the XML whereas I had in the other files. On checking again today I really think I must have been mistaken. Even the code shows that is impossible, as all of the runway stuff is written to all the filetypes at the same point, for each airport in turn.

I'll look at the length and water restrictions now, but could you please back-check and make sure the results you got which seemed wrong were not partly because of the sheer omission of runways with no defined thresholds?

BTW there is no option "/<", which explains why that had no effect.

MakeRwys /WaterOnly includes a gravel runway at IN53.

On this one, despite the fact that the BGL encoding for the surface type has been set to "Gravel", the nomenclature for the runway is W meaning water.  The only choice for the runway is blank, Left, Centre, Right and Water. The selection /WaterOnly" selects all those with W, no matter what the surface is encoded as.

On a similar vein to the earlier question:

On 9/2/2016 at 7:42 PM, RJP said:

For EDCY only 2 of the 4 water runways are listed.

This is the same as the previous/y answered question -- only those two runways have defined thresholds, see:

The only other one to look at is the />0 option I believe. Since I've no idea what the smallest one is, I'll start with />10000 to make sure the length check is applied.

Okay. On the length restrictions, by default I get a range of runway lengths from 1503 (shortest) up to 16568. Of course those < 1500 are eliminated by default in any case.

With />10000 I get 10001 to 16568.

With />500 I get runways from 526 (yes, 526 feet!), again up to 16568.  07VT is the example with 526 feet runways. 

Finally, with \>0, I get runways from 33 feet, up to 16568.  I'm sure the 33 foot runway is a dummy (it's for an add-on KTDW), one of those "ghost (invisible) runways thee to try and assert more control over AI traffic.  One of the shortest with a proper runway is probably this one with just 150 feet::

Hi Pete,

Hopefully the train holiday was good?

Many thanks for looking into it!

In at least some cases yes, I believe this is the case.  I wondered about AK02 but that's less than 1503 (see below).

Ah, I see (& I also see the W on the runway designator now, I really should have done so previously, sorry).

Hmmmm, I've just tried re-running (with />10) and the shortest I get is 1503, almost as though the switch is not being considered. I've just tried />500 too and the shortest I get is still (oddly!) 1503. Wonder if it can be a system related issue? FYI I'm using Win10, with command prompt run as admin.

Many thanks again Pete, yep I'm thinking now that as opposed to there being anything 'wrong' that for some reason the length switch is being ignored when I run, I wouldn't have a clue either why or how to confirm / workaround though.

Best regards

Richard
