Hi everyone, Just a minor request - both Saipan and Rota Intl. airports feature airport identification beacons, that currently aren't present in DCS. Saipan Here's the FAA website page on Saipan International Airport, it includes an airport diagram, with the position of the beacon marked (the 5 pointed star). The beacon is like a small lighthouse, mounted on a guyed pole, that flashes green and white and rotates at a rate of between 24-30RPM. The beacon is active between sunrise and sunset. Source. Here's a birdseye view, taken from Google Earth, I've circled the beacon in red: And here's essentially the same shot in DCS (-camera 180.413796 0.311381 101.060448 -cameradir -0.038673 -0.999246 0.003370): Note that the beacon isn't there, and the area is instead covered with trees that aren't there. Also note the multi-faceted radome in the bottom of the image, where there is in fact a small fuel tank (at least from March 2016 onwards). Fortunately Google Earth also has a very good streetview image of the beacon: And here's the same shot in DCS (-camera 180.404211 0.066700 101.085965 -cameradir -0.004077 0.080065 -0.996781): Obviously the beacon isn't there, but also notice that the area has a load of trees and foliage that shouldn't be there (the area should just be short grass). Tinian Like Saipan, Tinian also has a similar beacon, it has the same characteristics as Saipan. Source. Here's a birdseye view of the beacon, taken from Google Earth (beacon circled in red): And here's the same shot in DCS (-camera 166.321578 0.798042 90.293875 -cameradir -0.000000 -1.000000 -0.000000): Note that this area is a dirt track - in Google Earth it just looks like a grass clearing. Rota According to this, Rota also has an airport beacon, with again, the same characteristics. It can also be seen in this airport diagram: According to this it should be in the south-western corner of the apron, however I'm unsure where it is exactly (the area is cluttered with buildings and satellite imagery doesn't make it obvious where it is, there's also no streetview of the area or images readily available). Here's a satellite image sourced from Google Earth, I've circled in yellow where I think the beacon might be: And here's the same area in DCS (-camera 75.597527 0.362317 48.815373 -cameradir -0.050311 -0.998734 0.000000):

Hi everyone, I think I've found some possible geometry issues immediately to the north of Tinian international airfield. These areas comprise 2 dirt tracks that are more or less parallel, that are in turn parallel to the runway at Tinian international airfield, as well as a small clearing to the west: The small clearing to the west, should be basically flat. Going from south to north, in the centre, the clearing goes from 79m to 82m. In DCS the same area goes from 85m to 103m and is 95m at it's northern edge. Going from west to east, and again going by the centre, the elevation goes from ~80m at it's western edge, to ~81 at it's eastern. In DCS the same area goes from 88m at it's western edge to 102m at it's eastern. The southern track should also be basically flat, with only small inclines (DCS get's the locations of the inclines approximate accurate, but they are way too exaggerated in comparison). The track has 3 high areas, each separated by a low area. The high areas range from ~82 to 85m, and the low areas are only around 80m - much more level than DCS, where the high areas range around 95-100m and the low areas as low as 65m. The northern track essentially follows the same trend as the southern track, but in the middle high area, it reaches 87m - still far lower than DCS, where it reaches 96m. I realise this information might not be very useful in a practical sense, so here's a topographic map of the area: Here's the link to the Topographic map site, though for another point of reference, Google Earth also thinks the area should be fairly flat (varying between 79-82m). Here's the area as seen in ALT mode - unfortunately ALT mode isn't all that useful compared to a proper topographic map (it simply lacks the granularity and isn't a proper relief map). But you can at least the outlines of where the elevation changes. However, it doesn't appear to match the topography seen above. And here's the area as seen from above in DCS - the layout of the tracks and clearing is all spot on - just the geometry seems a little wonky, at least based on what I can dig up (camera position: -camera 167.407539 2.460112 90.088621 -cameradir 0.002876 -0.999996 -0.000007). There are other screenshots that I've taken that hopefully highlight the issue, though unfortunately I don't have RL reference shots to make a comparison. I'll put these in the spoiler below: If there's any other information I can provide, please let me know.- 1 reply

Hi everyone, Another small issue with the mesh of the Marianas map. The taxi-way/road leading to the WWII nuclear bomb pit, located to the north-west of North Field on Tinian has some geometry issues - there's a steep incline (I'd estimate ~30-35°), whereas IRL the area looks like it couldn't be more flat. Here's a Google Earth street-view of the area, looking to the south: And here's the same shot in DCS (-camera 176.207132 0.027198 91.657734 -cameradir -0.967976 -0.087994 -0.235114): Here's an overhead view in DCS, to really highlight the hill (-camera 176.250335 0.056178 91.713985 -cameradir -0.798708 -0.267452 -0.539013): And finally, here's a topographic map, sourced from here), Google Earth seems to agree with the topography (i.e the area should be almost completely flat), but deviates on the actual elevation. If I draw a straight line from the road, down in-between the 2 bomb-pits - bisecting the area, the line has a constant elevation of 29m, in Google Earth, the same line is 23m and in DCS, the same line starts off at 30m, then there's a hill at 31m, and then bomb loading pit area is 23m. It's as if the road referenced the topographic map above, but then bomb-pit was referencing Google Earth, and so there needed to be a steep hill in between the 2. In any case, flattening the area will resolve the issue.
