Re: [Flightgear-devel] improving VOR indication (patch for navradio.cxx/hxx)
On 08/28/2008 12:04 PM, Torsten Dreyer wrote: Here is a little patch that changes the behaviour of the VOR CDI and OFF-flag for indicators like the HSI when getting outside the range of the VOR station. The benefit is: - No more jitter for flag and needles That's not a benefit. The real instrument exhibits flicker when marginally out of range. Getting rid of the flicker is a Bad Idea. - Ability to animate the OFF-Flag with a smooth transition. That's not very important, far less important than getting the previous item right. In many situations, the real flag exhibits a fast transition, faster than the blink of an eye. - CDI and GS needle deflection shows correct values when in range That's not new. That should go without saying. and show some wrong indication when the range is exceeded Pilots don't like it when instruments show some wrong indication, particularly when the flag is not clearly in the OFF state. Wrong GS indications can be fatal. - CDI and GS needle start to move, even when the OFF flag is visible OK, but there are better ways to achieve this. The existing model of random flicker is _mostly_ a good idea, albeit imperfectly implemented. The real instrument exhibits flicker. 1) Slowing down the model's rate of flicker would be an improvement in realism. Right now it flickers at frame rate, whereas a coherence time on the order of a tenth of a second would be more realistic and more esthetically attractive. The patch to do this is vastly simpler *and* results in vastly more realism than trying to get rid of the flicker entirely. 2) Putting a time-based (not position-based) low-pass filter on the needle motion would be a good idea for multiple reasons, even when in range. This by itself would remove almost all of the esthetic objections to the flicker model. 3) Flag flicker by itself is much less of a problem, but if you really want smooth animation of the flag, again a time-based low-pass filter does the job. It should be asymmetric (fast-OFF, slow-ON). Also note that many instruments do *not* just attenuate the GS signal toward zero when out of range; for very good reasons they drive the needle to a full fly-up indication when out of range. Yes, there are some old, dumb instruments that do park the needle at zero, but it is a Bad Idea to assume that all instruments are old and dumb. Code to allow the instrument designer to implement whichever parking behavior is desired -- dumb or smart -- has been in the _Sport Model_ for years. - 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 Anders, I have committed your updates. I saw the goodyear blimp put on a show at EAA Oshkosh this year. It flew down the flight light and then did a roaring 45 degree climb-out. Not quite as awesome as the F-22, but it still was fun to watch after seeing it just float around for 2 days. Best regards, Curt.

Now, if you deploy the speedbrakes the lower clamp shell acts exactly like a flap at the rear end of the wing. If it weren't for the presence of the upper clamp shell, it wouldn't even produce much drag. I can assure you; it is modeled correctly now.

Ralf !? Yes, the Zeppelins are built at EDNY. Note that they differ from blimps by the fact that Zeppelins have a rigid inner structure while blimps are held in shape by the pressure of the gas. That's one of the tricks the guys at Zeppelin have, so they can attach the engines to the body of the Zeppelin instead of the cabin, which makes flying nearly silent for the passengers. With a hull without rigid structure, there is nothing to attach the engines to. They have space for 12 or 13 passengers. The hull generates dynamic lift and most of the time the ship is actually not lighter-than-air. I was told that typically they have a mass of about 2 tons, but a weight of around 700kg. If empty or with low fuel and payload, they are lighter-than-air. IIRC the rule-of-thumb figure for the transition between dynamic flight and hovering is at about 20kts IAS. They can activate a special system, which directly puts thrust-vector-control of the aft engine on the pilot's sidestick, allowing to control the ship the same way as with elevator and rudder. The side-engines can be rotated upwards and downwards, which is used during take-off and descend. These ships are flying at EDNY all the time. They're doing several roundtrips around the Lake of Constance area each day, given appropriate weather. Just today I had just vacated the runway coming back from a short local flight, and I saw one of them taking off. One is currently doing trips in London, and is bound to be shipped to San Francisco afterwards. IIRC it will take its homebase in Moffett Field. I don't have that livery yet and I had hoped to get some more detailed information on the geometry etc. The livery takes reference to the fact that the ship will be flying in the San Francisco area for tourist attraction. I'm not sure, but somehow I seem to remember that this is our standard scenery area ;-) That's all the info I could come up with at this late time of day ;-) Cheers, Ralf - 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
[Flightgear-devel] Way, way, way off topic!
This is way way way off topic, but some of you mind find it interesting and I have a very small connection to this adventure. http://junkraft.blogspot.com/ These guys just arrived in Honolulu after sailing a raft made out of plastic junk and a Cessna 310 fuselage from Los Angeles. They left on June 1 and met adverse winds and currents, so they struggled southward trying to not get blown into the Mexico coast and eventually, after getting about a month behind schedule, caught the westward trade winds and started jetting towards Hawaii (at about 1.5 - 2.0 kts). They brought with them a satellite tracking buoy made by the same company I do UAV work for. The buoy is designed to float in the open ocean, but they just carried it on board and it worked just the same. The batteries are recharged via solar panels, and it wakes up and reports it's gps position via satellite every 12 hours (which is configurable, but works just fine at 1.5 kts.) You can see their route on the trekme.com web page: http://trekme.com/junk/trek-262-junk-across-the-pacific The other reason I identified with their quest and checked their progress just about every day was that I had a loosely similar experience in Mar/Apr when I went out for 17 days north of Hawaii in a NOAA.gov research ship. We ate a bit better and traveled a bit faster, (and went further north into the debris field where it was much colder) but I experienced first hand the amount of plastic and debris that is floating around in the north pacific. I'm not a crazy environmentalist that runs around setting SUV's on fire, but I do think we could probably work a bit harder to take care of our earth. Plastic debris in our oceans is a problem that is getting worse and worse and a rate that at least makes me a bit sad. It's one of those problems that affects some areas more than others depending on currents and such, so you might go to your own beach and say what problem? But if you go out to the north pacific, there is an area the size of Texas where plastic bits and chunks accumulate due to currents and weather patterns. It is hard to find any spot in this region where you can't see some bit of debris somewhere around your ship. It's not like a trash heap where you can step from chunk to chunk, but the concentration is now getting high enough that you can always see some bit of something from anywhere in that area if you stop and look around for a few seconds. On our voyage we would stop every couple hours to take water samples down to a depth of 500m and as we held position and the current drifted by us at about 0.5 kts, I would spot a major chunk of something every 30-60 seconds ... things like a fishing buoy, a tooth brush, part of a plastic crate, part of a plastic 1 quart oil container, once I saw a 55 gallon drum, a 5 gallon pail, fragments of fishing net, and then just endless bits and pieces of non-identifyable stuff that once was part of something larger and identifyable. The problem is that even though the plastic breaks up into smaller and smaller bits, the bits themselves don't really degrade (at least not in a timely fashion) and this stuff ends up inside fish and wild life, and blah, blah, blah, now I am starting to sound like a crazy environmentalist. ;-) My point (if I have one?) is that there is a growing problem. I'm not in a position to know the severity of the problem in the grand scheme of life on this earth, but it is a problem and it's growing, and it is at least a little bit sad when you see it first hand (and this is just one of the areas in the oceans that are developing major plastic accumulation.) But aside from that problem, it was fun to follow this crazy raft/sailing adventure from Los Angeles to Hawaii, and it was even more fun that they used a tracking device that I've worked a bit with, and even more fun for me to follow along since after my one ocean trip in my life (which sort of almost intersected the same area they traveled through), I am now an ocean and sailing expert and can nod and agree knowingly with stuff they said in their blog. :-) Curt. -- Curtis Olson: http://baron.flightgear.org/~curt/ - 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
