Right ? Depends what you mean - I'm parsing the name of the marker beacon / ILS to find the matching runway. This isn't a new feature - I added that logic last year or more - so I could have a FGRunway* runway() accessor on FGNavRecord. It's the sqlite rowID of the airport record - both in the positioned table, but also the 'airports' table. Ah, indeed, the rowid - that's neat. The rowid wasn't that obvious from the SQL dump I was staring at (I simply didn't care counting the rows myself ;-) Right, by default sqlite doesn't include the rowid column in SELECT results - you need to ask for it explicitly.

Actually no, this needs some extensions to airportinfo() I think. Correct. We don't have that information available. bonus feature: a wind indicator arrow showing the wind direction and speed based on current environment. While that's useful for the current location, I don't think it's all that useful for airports elsewhere, which is a particular use-case for the dialog. If we could enhance the airportinfo() to include the actual METAR (or indeed expose a metar() call via Nasal), we could usefully display the current METAR for the selected airport, as well as show a wind arrow and the best-runway. I think I should go the full way here, and make a NasalMetar object that can be initialised as a location, and fires a Nasal callback when its data changes, i.e when it loads. We have all the pieces for this already, and glueing them together in this way would allow lots of interesting FMS and other features. I'll try to get that done in the next few days.

I may end up doing this for the route-path in the map widget, depending on performance. I don't think that Nasal is the bottleneck here, but I'll check it. I think that most time is spend with tessellation of the path but I'm also not sure about this one. Drawing multiple quads at once should be possible if putting all quads in a single path (Start a new subpath/quad use canvas.Path.moveTo() or canvas.Path.VG_MOVE_TO). I'll have a look if ShivaVG really creates just a list of quads and otherwise modify it to do so. If you need an aircraft symbol, eg. for showing the currently selected position have a look at my fgdata branch: https://gitorious.org/~tomprogs/fg/toms-fgdata/blobs/canvas/gui/dialogs/images/icon-aircraft.svg https://gitorious.org/~tomprogs/fg/toms-fgdata/blobs/canvas/gui/dialogs/map-canvas.xml#line234 It's looking really good, if we/I/Thomas could get panning and ideally smooth mouse-wheel zooming working, it would be fantastic.

Re: [Flightgear-devel] Nav-cache
would any of these changes have affected the Equipment/map performance ? I get a lot of disc activity now while panning the map ... and it takes 10 -15 seconds now before it refreshes , and thats with every mouse drag.This only used to happen when zooming out , and the refresh time was much shorter...

Re: [Flightgear-devel] Nav-cache
Yes, the map performance is 'different'. However I'm about to port the map to use the canvas, so please forgive the current performance issues for a little while.
