November 7, 1990 This is the most recent version of the file, DCADCAJB.SC1 file, with several additions from the first one that was uploaded in October. I have also included a dynamic scenery file, DCADCAJB.DY1, which adds a little traffic during the first few minutes of running the scenery. I have also included two mode files which will place you in my "personalized" Cessna (If you use the N2722JB.SIM file, which is also included). One, DCARWY18.MOD (listed as "DCA Runway 18 Startup"), will place you at the take off threshold for runway 18. Before taking off right away, I'd suggest checking runway 15, off to your right, for traffic. There is a Lear that's just been cleared for takeoff, and a Cessna on about a four mile final for the same runway. There are also a couple of passenger jets on the River Visual Approach; They should both come in before the taxiing 767 gets too close to you. Check your 8 o'clock view to see them coming in. After the second one clears the numbers, you'd better assume you've been "cleared into position", and nudge out onto the runway...that 767 coming up the taxiway looks like he's in a hurry! As you take off, give the airport a look over your right shoulder; it's quite a sight! The other mode, DCARVIS.MOD, will place you at the entry point for the River Visual Approach to runway one eight. You'll be about 11 miles out, inbound at 148 degrees on the 328 radial of the DCA VOR. If you have the instrument approach plate for the River Visual Approach, you're all set up to fly it on in to DCA. If you don't have the approach plate, you can still fly the approach, with the following procedure: The River Visual Approach to runway one eight is a fairly straightforward approach. Assume you've already been given clearance and vectors for the approach from Washington Center, which have brought you to this point, which is where the approach plate description begins. You should be at 3000 MSL over the Potomac river at about 10DME on the DCA VOR (111.0) 328 radial (148 degrees inbound). You have the option of following the river on down, or following the radial to a point abeam the Georgetown Reservoir (at 4nm) and at that point start following the river to the airport. Recommended altitudes are as follows: 3000 MSL at entry; 1800 MSL at 6nm (or abeam the Dalecarlia Reservoir, or just before Chain Bridge); and 900 MSL abeam Georgetown Reservoir, at 4nm. Then it's just follow the river and establish your own descent rate on down to the runway (elevation, 13 feet). Most of the "action" in the dynamic scenery takes place in the first 6 or 8 minutes of activating the file, so you won't see much of it if you start up with the DCARVIS.MOD mode. Of course, I used that mode when I recorded one of the approach patterns followed by a 767, and you may see him suspended in the air in front of you if you start up in that mode, or restart the dynamic scenery at that point. Don't worry about passing him by...he'll catch up! Then when you land, you and he can figure out who reports whom for the separation violation! Also, be advised that he is being followed by another 767 just a couple of minutes behind him, so you may be doing some bobbing and weaving to get out of their way if you start up in this mode. I'd recommend starting up in the DCARWY18.MOD configuration, taking off after the traffic has cleared, and once airborne, make a long wide right turn out towards the north west. When you get out about 10 miles, switch modes to the DCARVIS.MOD (Listed as "DCA RWY 18-River Visual"). The DCADCAJB.SC1 file includes just about all the navaids that are used in making various instrument approaches to DCA. They are a part of the .SC1 file, so can be used even if you don't have SD-7. Even if you do, some of the navaids included in the .SC1 file are not included in the SD-7 data. The navaids included are: DCA () VOR (111.0) Andrews (ADW) VOR (113.1) Nottingham (OTT) VOR (113.7) Baltimore (BAL) VOR (115.1) Armel (AML) VOR (113.5) Oxonn (DC) NDB (332) Georgetown (GTN) NDB (323) ILS-Runway 36 (I-DCA) (109.9) Outer Marker (also Oxonn NDB) Middle Marker These are each referenced in one or more of the various approach plates used for instrument approaches to DCA, and are pretty much in the right positions, relative to each other, with the DCA VOR being used as the principle reference point in the scenery design. I touched up a few of the taxiways, but there are still a few small gaps, which you may notice while taxiing. This was my first effort at doing an airport in this detail, and I learned after having completed it that if you overlap a polygon being used to form a taxiway slightly over the runway, at its intersection with the runway, after you "Add" it, the polygon will slip under the runway, and make for a nice snug fit. I had tried to place them by lining the polygon points up along the runway edge, and it doesn't seem to work quite as well. The suggestion to overlap the polygons came from Rick Lee, Section Leader for the Flight simulator/Aviation section in GAMERS, on CompuServe.
